Ulmus americana was first described and named by Carl Linnaeus in his Species Plantarum, published in 1753. No subspecies or varieties are currently recognized within the species.

Ulmus americana, generally known as the American elm or, less commonly, as the white elm or water elm, is a species native to eastern North America, occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 °C (−44 °F). Trees in areas unaffected by Dutch elm disease can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to Dutch elm disease; when it was felled in 1968, a tree-ring count established that it had germinated in 1701.

For over 80 years, U. americana has been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a recent study by the Agricultural Research Service of the United States Department of Agriculture has found that about 20% of wild American Elms are in fact diploid, and may even constitute another species.

Ehretia anacua is medium-sized tree found in eastern Mexico and southern Texas in the United States. It is a member of the borage family, Boraginaceae. One of its common names, Anacua, is derived from the Mexican Spanish word Anacahuite, as is that of the related Cordia boissieri, the Anacahuita. That word in turn is derived from the Nahuatl words āmatl, meaning "paper," and quatitl, meaning "tree,] possibly referring to the bark. It is also known as Knockaway, a corruption of Anacua, and Sandpaper Tree.

Anacua reaches a height of 20–45 ft (6.1–13.7 m) and a diameter of 0.3 m (0.98 ft), often producing suckers or multiple trunks. The bark is reddish-brown to gray with narrow furrows and peeling scales. The dark green leaves are 3–8 cm (1.2–3.1 in) and 2–4 cm (0.79–1.57 in) wide and elliptical or ovate. Their upper surfaces are remarkably rough, feeling like low-grade sandpaper. Anacua is a partial evergreen, replacing some of the leaves in early spring. Abundant white flowers form in panicles or cymes 5–7.5 cm (2.0–3.0 in) in length at the ends of twigs, making trees appear to be covered in snow when in bloom from spring to summer. Flowers are 8 mm (0.31 in) wide and have 5 corolla lobes. The fruits are spherical drupes 8 mm in diameter and yellowish-orange. The drupes contain two stones, each with two seeds. In addition to being edible by humans, the drupes are eaten by mammals and birds such as the Clay-colored Thrush. The lifespan of an Anacua is at least 50 years.

Fraxinus velutina (velvet ash or Arizona ash or Modesto ash) is a species of Fraxinus native to southwestern North America, in the United States from southern California east to Texas, and in Mexico from northern Baja California east to Coahuila and Nuevo León.

Fraxinus velutina is a small deciduous tree growing to 10 m tall, with a trunk up to 30 cm diameter. The bark is rough gray-brown and fissured, and the shoots are velvety-downy. The leaves are 10–25 cm long, pinnately compound with five or seven (occasionally three) leaflets 4 cm or more long, with an entire or finely serrated margin. The flowers are produced in small clusters in early spring; it is dioecious, with male and female flowers on separate trees. The fruit is a samara 1.5–3 cm long, with an apical wing 4–8 mm broad.

Fraxinus velutina is closely related to Fraxinus latifolia (Oregon Ash) and Fraxinus pennsylvanica (Green Ash), replacing these species to the south of their respective ranges; it intergrades with F. latifolia in central California (around Kern County, without a clear boundary between the species.

Prunus serotina, commonly called black cherry, wild black cherry, rum cherry, or mountain black cherry, is a woody plant species belonging to the genus Prunus. This cherry is native to eastern North America: from eastern Canada through southern Quebec and Ontario; south through the eastern United States to Texas and central Florida; with disjunct populations in Arizona and New Mexico; and in the mountains of Mexico and Guatemala.

A mature black cherry can easily be identified in a forest by its very broken, dark grey to black bark, which has the appearance of very thick, burnt cornflakes. However, for about the first decade or so of its life, the bark is thin, smooth, and striped, resembling that of a birch. It can also quickly be identified by its long, shiny leaves resembling those of a sourwood, and by an almond-like odor released when a young twig is scratched and held close to the nose.

Prosopis glandulosa, commonly known as honey mesquite, is a species of small to medium-sized, thorny shrub or tree in the legume family (Fabaceae). It is native to the Southwestern United States and Mexico, growing as far north as southern Kansas and as far east as the eastern fifth of Texas, where average annual rainfall is in excess of 40 inches (100 cm). It can be part of the Mesquite Bosque plant association community.

It has been introduced to at least a half-dozen other countries. The IUCN considers it as one of the world's 100 worst invasive species outside its native habitat range.
Despite its invasive nature, this tree has an array of features that make it useful: it grows extremely rapidly, has very dense shade, produces a seed pod in abundance that is eaten by animals and humans alike, and it is also readily available firewood.

Salix nigra (black willow) is a species of willow native to eastern North America, from New Brunswick and southern Ontario west to Minnesota, and south to northern Florida and Texas.

It is a medium-sized deciduous tree, the largest North American species of willow, growing to 10–30 m (33–98 ft) tall, exceptionally up to 45 m (148 ft), with a trunk 50–80 centimetres (20–31 in) diameter. The bark is dark brown to blackish, becoming fissured in older trees, and frequently forking near the base. The shoots are slender and variable in color from green to brown, yellow or purplish; they are (like the related European Salix fragilis) brittle at the base, snapping evenly at the branch junction if bent sharply. The foliage buds are 2–4 millimetres (0.079–0.157 in) long, with a single, pointed reddish-brown bud scale. The leaves are alternate, long, thin, 5–15 centimetres (2.0–5.9 in) long and 0.5–2 centimetres (0.20–0.79 in) broad, usually somewhat falcate, dark, shiny green on both sides or with a lighter green underside, with a finely serrated margin, a short petiole and a pair of small stipules.

It is dioecious, with small, greenish yellow to yellow flowers borne on catkins 2.5–7.5 centimetres (0.98–2.95 in) long in early spring at the same time as the new leaves appear. The fruit is a 5 millimetres (0.20 in) capsule which splits open when mature to release the numerous minute, down-covered seeds. The leaves turn a lemon yellow in the fall. It is typically found along streams and in swamps.

Maclura pomifera, commonly called Osage orange, hedge apple, horse apple, monkey ball, bois d'arc, bodark, or bodock is a small deciduous tree or large shrub, typically growing to 8–15 metres (26–49 ft) tall. It is a Carolinian species. It is dioecious, with male and female flowers on different plants. The fruit, from a multiple fruit family, is roughly spherical, but bumpy, and 7.6–15.2 centimetres (3–6 in) in diameter. It is filled with a sticky white latex. In fall, its color turns a bright yellow-green. Despite the name "Osage orange," it is not closely related to the orange.

Maclura is closely related to the genus Cudrania, and hybrids between the two genera have been produced. In fact, some botanists recognize a more broadly defined Maclura that includes species previously included in Cudrania and other genera of Moraceae.

Osajin and pomiferin are flavonoid pigments present in the wood and fruit, comprising about 10% of the fruit's dry weight. The plant also contains the flavonol morin. The Osage orange is commonly used as a tree row windbreak in prairie states, which gives it one of its colloquial names, "hedge apple".

Acer negundo is a species of maple native to North America. Box elder, boxelder maple, ash-leaved Maple, and maple ash are its most common names in the United States; in Britain and Ireland it is also known as ashleaf maple.

Other variant names, some of which are regional, include: In Canada it is commonly known as Manitoba Maple and occasionally as Elf Maple. Other names include Ash Maple, Ash-leaf Maple, Black Ash, California Boxelder, Cutleaf Maple, Cut-leaved Maple, Negundo Maple, Red River Maple, Stinking Ash, Sugar Ash, Three-leaved Maple, and Western Boxelder. In Russia it is called American Maple (Russian: американский клён) as well as Ash-leaf Maple (Russian: клён ясенелистный).

Acer negundo is a small, usually fast-growing and fairly short-lived tree that grows up to 10–25 metres (33–82 ft) tall, with a trunk diameter of 30–50 centimetres (12–20 in), rarely up to 1 metre (3.3 ft) diameter. It often has several trunks and can form impenetrable thickets.

The shoots are green, often with a whitish to pink or violet waxy coating when young. Branches are smooth, somewhat brittle, and tend to retain a fresh green colour rather than forming a bark of dead, protective tissue. The bark on its trunks is pale gray or light brown, deeply cleft into broad ridges, and scaly.

Unlike most other maples (which usually have simple, palmately lobed leaves), Acer negundo has pinnately compound leaves that usually have three to seven leaflets. Simple leaves are also occasionally present; technically, these are single-leaflet compound leaves. Although some other maples (such as Acer griseum, Acer mandshuricum and the closely related A. cissifolium) have trifoliate leaves, only A. negundo regularly displays more than three leaflets.

Cinnamomum camphora (commonly known as camphor tree, camphorwood or camphor laurel) is a large evergreen tree that grows up to 20–30 m (66–98 ft) tall. The leaves have a glossy, waxy appearance and smell of camphor when crushed. In spring, it produces bright green foliage with masses of small white flowers. It produces clusters of black, berry-like fruit around 1 cm (0.39 in) in diameter. Its pale bark is very rough and fissured vertically.

Cinnamomum camphora is native to China south of the Yangtze River, Taiwan, southern Japan, Korea, and Vietnam, and has been introduced to many other countries.

In Japan, where the tree is called kusunoki, five camphor trees are known with a trunk circumference above 20 m, with the largest tree (Kamou no Ohkusu) reaching the circumference of 24.22 m.

Catalpa bignonioides is a species of Catalpa that is native to the southeastern United States in Alabama, Florida, Georgia, Louisiana, and Mississippi. Common names include southern catalpa, cigar tree, and Indian bean tree. It is a medium-sized deciduous tree growing to 15–18 metres (49–59 ft) tall, with a trunk up to 1 metre (3 ft 3 in) diameter, with brown to gray bark, maturing into hard plates or ridges. The short thick trunk supports long and straggling branches which form a broad and irregular head. The roots are fibrous and branches are brittle. Its juices are watery and bitter.

The leaves are large and heart shaped, being 20–30 cm long and 15–20 cm broad. The bright green leaves appear late and as they are full grown before the flower clusters open, add much to the beauty of the blossoming tree. They secrete nectar, a most unusual characteristic for leaves, by means of groups of tiny glands in the axils of the primary veins.

The flowers are 2.5–4 cm across, trumpet shaped, white with yellow spots inside; they grow in panicles of 20-40. In the northern states of the USA, it is a late bloomer, putting forth great panicles of white flowers in June or early in July when the flowers of other trees have mostly faded. These cover the tree so thickly as almost to conceal the full grown leaves.

Ulmus crassifolia Nutt., the Texas Cedar Elm or simply Cedar Elm, is a deciduous tree native to south central North America, mainly in southern and eastern Texas, eastern Oklahoma, Arkansas and Louisiana, with small populations in western Mississippi, southwest Tennessee and northwestern Florida; it also occurs in northeastern Mexico. The tree typically grows well in flat valley bottom areas referred to as 'Cedar Elm Flats'. The common name 'Cedar Elm' is derived from the trees' association with juniper trees, locally known as cedars.

The Cedar Elm is a medium-sized to large deciduous tree growing to 24 – 27 m tall with a rounded crown. The leaves are small, 2.5 – 5 cm long by 1.3 – 2 cm broad, with an oblique base, and distinguish it from Ulmus serotina with which it readily hybridizes in the wild. Leaf fall is late in the year, often in early winter. The wind-pollinated apetalous perfect flowers are produced in the late summer or early fall; they are small and inconspicuous, with a reddish-purple color. The fruit is a small winged samara 8 – 10 mm long, maturing quickly after the flowering in late fall.

Prunus caroliniana, known as the Carolina Cherry Laurel, with syns. Cherry Laurel, Carolina Cherry, Laurelcherry or Wild Mock Orange, is a flowering tree native to the Southeastern United States, from North Carolina south to Florida and westward to eastern Texas. It was once classified as Laurocerasus caroliniana. It is not to be confused with its European relative Prunus laurocerasus, which is also called Cherry Laurel, though mainly known as English Laurel in the U.S.

Prunus caroliniana is a small to medium-sized evergreen tree which grows to about 8–13 m tall, with a spread of about 6–9 m. The leaves are dark green, alternate, glossy, coriaceous, elliptic to oblanceolate, 5–12 cm long, usually with an entire (smooth) margin, but occasionally serrulate (having subtle serrations), and with cuneate bases. The twigs are red to grayish brown, slender, and glabrous. (Reproductively mature trees have entire margins, whereas immature ones often have serrations.)

The white to cream-colored flowers are produced in racemes (stalked bunches) 5–8 cm long in the late winter to early spring. The fruits are tiny black cherries about 1 cm in diameter, which persist through winter and are primarily consumed by birds (February - April).

The leaves and branches contain high amounts of cyanogenic glycosides that break down into hydrogen cyanide when damaged, making it a potential toxic hazard to grazing livestock and children. Due to this, it is considered highly deer-resistant. When crushed, its leaves and green twigs emit a fragrance described as resembling maraschino cherries or almond extract.

Quercus pagoda, the cherrybark oak, is one of the most highly valued red oaks in the southern United States. It is larger and better formed than southern red oak and commonly grows on more moist sites. Its strong wood and straight form make it an excellent timber tree. Many wildlife species use its acorns as food, and cherrybark oak makes a fine shade tree. Cherrybark oak was formerly considered to be a subspecies of southern red oak, Quercus falcata, subsp pagodafolia.

The name pagoda refers to the regularly tiered shape of cherrybark's leaves, which are reminiscent of the shape of a pagoda. Its simple, alternate leaves generally have V-shaped bases, uniformly shaped and deeply incised lobes (5 to 11), and short, broad, uncurved tips. Leaves are 7 to 10 inches long and up to 7 inches wide. Leaves are dark green, smooth, and shiny on the surface; undersides are paler and pubescent.

The name 'cherrybark' comes from its similarity to the bark of black cherry. The bark is gray and has scaly, narrow ridges.

Pistacia chinensis (English: Chinese pistache; Chinese: 黄连木; pinyin: huángliánmù) is a small to medium-sized tree in the genus Pistacia in the cashew family, Anacardiaceae, native to central and western China. It is hardy, can withstand harsh conditions and poor quality soils, and grows up to 20 m. The leaves are deciduous, alternate, pinnate, 20-25 cm long, with 10 or 12 leaflets, the terminal leaflet usually absent. The flowers are produced in panicles 15-20 cm long at the ends of the branches; it is dioecious, with separate male and female plants. The fruit is a small red drupe, turning blue when ripe, containing a single seed. This species is planted as a street tree in temperate areas worldwide due to its attractive fruit and autumn foliage.

Horticulturally, it is a popular choice for street trees in urban settings because it is very drought tolerant and can survive harsh environments. It is also used as an understock for Pistacia vera. In China, the oil from the seeds is used for biodiesel production. The wood is used for production of furniture and yields a yellow dye.

Citrus is a common term and genus (Citrus) of flowering plants in the rue family, Rutaceae.

The most recent research indicates an origin in Australia, New Caledonia and New Guinea. Some researchers believe that the origin is in the part of Southeast Asia bordered by Northeast India, Burma (Myanmar) and the Yunnan province of China, and it is in this region that some commercial species such as oranges, mandarins, and lemons originated. Citrus fruit has been cultivated in an ever-widening area since ancient times; the best-known examples are the oranges, lemons, grapefruit, and limes.

These plants are large shrubs or small to moderate-sized trees, reaching 5–15 m (16–49 ft) tall, with spiny shoots and alternately arranged evergreen leaves with an entire margin. The flowers are solitary or in small corymbs, each flower 2–4 cm (0.79–1.57 in) diameter, with five (rarely four) white petals and numerous stamens; they are often very strongly scented.

Citrus fruits are notable for their fragrance, partly due to flavonoids and limonoids (which in turn are terpenes) contained in the rind, and most are juice-laden. The juice contains a high quantity of citric acid giving them their characteristic sharp flavour. The genus is commercially important as many species are cultivated for their fruit, which is eaten fresh, pressed for juice, or preserved in marmalades and pickles.

They are also good sources of vitamin C and flavonoids. The flavonoids include various flavanones and flavones.

Populus deltoides, the eastern cottonwood, is a cottonwood poplar native to North America, growing throughout the eastern, central, and southwestern United States, the southernmost part of eastern Canada, and northeastern Mexico. It is a dicot.

The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. The twigs are grayish-yellow and stout, with large triangular leaf scars. The winter buds are slender, pointed, 1–2 cm long (.039–0.79 inches), yellowish brown, and resinous. It is one of the fastest growing trees in North America. In Mississippi River bottoms, height growth of 10-15 ft per year for a few years are possible. Sustained height growth of 5 feet height growth and 1 inch diameter growth per year for 25 years is common.

The leaves are large, deltoid (triangular), 4–10 cm (1.6–3.9 inches) long and 4–11 cm (1.6–4.3 inches) broad with a truncated (flattened) base and a petiole 3–12 cm (1.2–4.7 inches) long. The leaf is very coarsely toothed, the teeth are curved and gland tipped, and the petiole is flat; they are dark green in the summer and turn yellow in the fall (but many cottonwoods in dry locations drop their leaves early from the combination of drought and leaf rust, making their fall color dull or absent). Due to the flat stem of the leaf, the leaf has the tendency to shake from even the slightest breeze. This is one of the identifying characteristics.

It is dioecious, with the flowers (catkins) produced on single-sex trees in early spring. The male (pollen) catkins are reddish-purple and 8–10 cm (2.1–3.9 inches) long; the female catkins are green, 7–13 cm (2.8–5.1 inches) long at pollination, maturing 15–20 cm (6.9–7.9 inches) long with several 6–15 mm (0.24–0.59 inch) seed capsules in early summer, which split open to release the numerous small seeds attached to cotton-like strands.

Juniperus virginiana — its common names include red cedar, eastern red-cedar, eastern redcedar, eastern juniper, red juniper, pencil cedar, and aromatic cedar — is a species of juniper native to eastern North America from southeastern Canada to the Gulf of Mexico and east of the Great Plains. Further west it is replaced by the related Juniperus scopulorum (Rocky Mountain Juniper) and to the southwest by Juniperus ashei (Ashe Juniper).

Juniperus virginiana is a dense slow-growing coniferous evergreen tree that may never become more than a bush on poor soil, but is ordinarily from 5–20 m or 16–66 ft (rarely to 27 m or 89 ft) tall, with a short trunk 30–100 cm or 12–39 in (rarely 170 cm or 67 in) diameter. The oldest tree reported, from Missouri, was 795 years old. The bark is reddish-brown, fibrous, and peels off in narrow strips. The leaves are of two types; sharp, spreading needle-like juvenile leaves 5–10 cm (2.0–3.9 in) long, and tightly adpressed scale-like adult leaves 2–4 mm (0.079–0.157 in) long; they are arranged in opposite decussate pairs or occasionally whorls of three. The juvenile leaves are found on young plants up to 3 years old, and as scattered shoots on adult trees, usually in shade.

The seed cones are 3–7 mm (0.12–0.28 in) long, berry-like, dark purple-blue with a white wax cover giving an overall sky-blue color (though the wax often rubs off); they contain one to three (rarely up to four) seeds, and are mature in 6–8 months from pollination. The Juniper berry is an important winter food for many birds, which disperse the wingless seeds. The pollen cones are 2–3 mm (0.079–0.118 in) long and 1.5 mm (0.059 in) broad, shedding pollen in late winter or early spring. The trees are usually dioecious, with pollen and seed cones on separate trees.

Fraxinus pennsylvanica (green ash or red ash) is a species of ash native to eastern and central North America, from Nova Scotia west to southeastern Alberta and eastern Colorado, south to northern Florida, and southwest to eastern Texas. It has spread and become naturalized in much of the western United States and also in central Europe from Spain to Russia.

It is a medium-sized deciduous tree reaching 12–25 m (rarely to 45 m) tall with a trunk up to 60 cm in diameter. The bark is smooth and gray on young trees, becoming thick and fissured with age. The winter buds are reddish-brown, with a velvety texture. The leaves are 15–30 cm long, pinnately compound with seven to nine (occasionally five or eleven) leaflets, these 5–15 cm (rarely 18 cm) long and 1.2–9 cm broad, with serrated margins and short but distinct, downy petiolules a few millimeters long. They are green both above and below. The autumn color is golden-yellow and depending on the climate, Green Ash's leaves may begin changing color the first week of September. The flowers are produced in spring at the same time as the new leaves, in compact panicles; they are inconspicuous with no petals, and are wind-pollinated. The fruit is a samara 2.5-7.5 cm long comprising a single seed 1.5–3 cm long with an elongated apical wing 2–4 cm long and 3–7 mm broad.

It is sometimes divided into two varieties, Fraxinus pennsylvanica var. pennsylvanica (red ash) and Fraxinus pennsylvanica var. lanceolata (Borkh.) Sarg. (syn. var. subintegerrima (Vahl) Fern.; green ash) on the basis of the hairless leaves with narrower leaflets of the latter, but the two intergrade completely, and the distinction is no longer upheld by most botanists.

Ulmus parvifolia, commonly known as the Chinese elm or Lacebark Elm, is a species native to China, India, Taiwan, Japan, North Korea, and Vietnam. It has been described as "one of the most splendid elms, having the poise of a graceful Nothofagus.

A small to medium deciduous, semi-deciduous (rarely semi-evergreen) tree growing to 10–18 m (30–60 ft) tall and 15-20 m (50-70 ft) wide with a slender trunk and crown. The leathery, lustrous green single-toothed leaves are small, 2–5 cm long by 1–3 cm broad, and often retained as late as December or even January in Europe and North America. The apetalous wind-pollinated perfect flowers are produced in early autumn, small and inconspicuous. The fruit is a samara, elliptic to ovate-elliptic, 10–13 mm long by 6–8 mm broad. The samara is mostly glabrous, the seed at the centre or toward the apex, borne on a stalk 1–3 mm in length; it matures rapidly and disperses by late autumn. The trunk has a handsome, flaking bark of mottled greys with tans and reds, giving rise to its other common name, the Lacebark Elm, although scarring from major branch loss can lead to large canker-like wounds.

Leucaena retusa is a species of flowering plant in the legume family known by the common names littleleaf leadtree, goldenball leadtree, wahoo tree, and lemonball. It is native to Chihuahua and Coahuila in Mexico and Texas in the United States. It also occurs in New Mexico.

This plant is a small tree that can reach 25 feet in height. The leaves are bright green to blue-green in color and each is divided into several leaflets. The spherical flowers are yellow to white in color. The trees flower in April through October and they tend to flower profusely after rain. The fruit is a legume pod up to 10 inches in length. The wood is weak and breaks easily.

This tree grows in dry habitat and it is drought-tolerant. It is adapted to alkaline soils and full sunlight. It is often cultivated as an ornamental plant for its attractive appearance. It is easily grown from seed and it will reseed itself. It can even become weedy. It is not considered useful as a honey plant or for its wood. Animals such as livestock and white-tailed deer find the herbage palatable. The seeds are also high in protein.

Ligustrum japonicum (Japanese privet or wax-leaf privet; Japanese: ネズミモチ) is a species of Ligustrum (privet) native to central and southern Japan (Honshū, Shikoku, Kyūshū, Okinawa) and Korea. It is widely cultivated in other regions, and is naturalized in California and in the southeastern United States from Texas to Virginia.

It is an evergreen shrub or small tree growing to 2–5 m (rarely 6 m) tall, with smooth, pale grey-brown bark on the stems. The leaves are opposite, 5–10 cm long and 2–5 cm broad, glossy dark green above, paler glaucous to yellowish green below, thick and leathery textured, and with an entire margin. The flowers are white, with a four-lobed corolla 5–6 mm long; they are borne in clusters 7–15 cm long in early summer.

The fruit is an oval drupe, 10 mm long, ripening purple-black with a glaucous waxy bloom in early winter; in Japan they are popularly likened to mouse or rat droppings. The species is closely related to the Chinese Ligustrum lucidum, differing in its smaller size (L. lucidum making a tree to over 10 m tall), and elongated oval (not subglobose) fruit.

Quercus virginiana, also known as the southern live oak, is a normally evergreen oak tree native to the southeastern United States. Though many other species are loosely called live oak, the southern live oak is particularly iconic of the Old South.

A large number of common names are used for this tree, including "Virginia live oak", "bay live oak", "scrub live oak", "plateau oak", "plateau live oak", "escarpment live oak", and (in Spanish) "encino". It is also often just called "live oak" within its native area, but the full name "southern live oak" helps to distinguish it from other live oaks, a general term for any evergreen species of oak.

This profusion of common names partly reflects an ongoing controversy about the classification of various live oaks, in particular its near relatives among the white oaks (Quercus subgenus Quercus, section Quercus). Some authors recognize as distinct species the forms others consider to be varieties of Quercus virginiana. Notably, the following two taxa, treated as species in the Flora of North America, are treated as varieties of southern live oak by the United States Forest Service: the Texas live oak, Quercus fusiformis (Q. virginiana var. fusiformis) and the sand live oak, Quercus geminata (Q. virginiana var. geminata).

Matters are further complicated by southern live oaks hybridizing with both the above two species, and also with dwarf live oak (Q. minima), swamp white oak (Q. bicolor), Durand oak (Q. durandii), overcup oak (Q. lyrata), bur oak (Q. macrocarpa), and post oak (Q. stellata).

Pinus taeda, commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from central Texas east to Florida, and north to Delaware and southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in Southeastern US.

The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas. Loblolly pine is the first among over 100 species of Pinus to have its complete genome sequenced. As of March 2014 it is the organism having the largest sequenced genome size. Its genome with 20.15 billion base pairs is seven times larger than that of humans.

Loblolly pine can reach a height of 30–35 m (98–115 ft) with a diameter of 0.4–1.5 m (1.3–4.9 ft). Exceptional specimens may reach 50 m (160 ft) tall, the largest of the southern pines. Its needles are in bundles of three, sometimes twisted, and measure 12–22 cm (4.7–8.7 in) long; an intermediate length for southern pines, shorter than those of the longleaf pine or slash pine, but longer than those of the shortleaf pine and spruce pine. The needles usually last up to two years before they fall, which gives the species its evergreen character. Although some needles fall throughout the year due to severe weather, insect damage, and drought, most needles fall during the autumn and winter of their second year. The seed cones are green, ripening pale buff-brown, 7–13 cm (2.8–5.1 in) in length, 2–3 cm (0.79–1.18 in) broad when closed, opening to 4–6 cm (1.6–2.4 in) wide, each scale bearing a sharp 3–6 mm spine.

The tallest loblolly pine currently known, which is 51.4 m (169 ft) tall, and the largest, which measures 42 cubic meters in volume, are in Congaree National Park.

Morus rubra, commonly known as the Red Mulberry, is a species of mulberry native to eastern North America. It is found from Ontario and Vermont in the north down to southern Florida, and west to southeast South Dakota and central Texas.

Common in the United States, it is listed as an endangered species in Canada, and is susceptible to hybridization with the invasive White Mulberry (M. alba), introduced from Asia.

Red Mulberry is a deciduous tree, growing to 10–15 m tall, rarely 20 m, with a trunk up to 50 cm diameter. The leaves are alternate, 7–14 cm long and 6–12 cm broad, simple, broadly cordate, with a shallow notch at the base, typically unlobed on mature trees although often with 2-3 lobes, particularly on young trees, and with a finely serrated margin. The upper surface of the leaves is noticeably rough, similar in texture to fine sandpaper, and unlike the lustrous upper surface of the leaves of White Mulberry (M. alba). The underside of the leaves is covered with soft hairs. The leaf petiole exudes milky sap when severed. Red Mulberry is hardy to subzero temperatures, relatively hardy to drought, pollution, and poor soil, though the White Mulberry is hardier. The flowers are relatively inconspicuous: small, yellowish green or reddish green, and opening as leaves emerge. Male and female flowers are usually on separate trees although they may occur on the same tree.

The fruit is a compound cluster of several small drupes, similar in appearance to a blackberry, 2–3 cm long, when it is ripening it is red or dark purple, edible and very sweet with a good flavor.

The pecan (Carya illinoinensis) is a species of hickory native to Mexico and the southcentral and southeastern regions of the United States.

"Pecan" is from an Algonquian word meaning a nut requiring a stone to crack.

The pecan tree is a large deciduous tree, growing to 20–40 m (66–131 ft) in height, rarely to 44 m (144 ft).[2] It typically has a spread of 12–23 m (39–75 ft) with a trunk up to 2 m (6.6 ft) diameter. A 10-year-old sapling will stand about 5 m (16 ft) tall. The leaves are alternate, 30–45 cm (12–18 in) long, and pinnate with 9–17 leaflets, each leaflet 5–12 cm (2.0–4.7 in) long and 2–6 cm (0.79–2.36 in) broad.

A pecan, like the fruit of all other members of the hickory genus, is not truly a nut, but is technically a drupe, a fruit with a single stone or pit, surrounded by a husk. The husks are produced from the exocarp tissue of the flower, while the part known as the nut develops from the endocarp and contains the seed. The husk itself is aeneous, oval to oblong, 2.6–6 cm (1.0–2.4 in) long and 1.5–3 cm (0.59–1.18 in) broad. The outer husk is 3–4 mm (0.12–0.16 in) thick, starts out green and turns brown at maturity, at which time it splits off in four sections to release the thin-shelled nut.

The seeds of the pecan are edible, with a rich, buttery flavor. They can be eaten fresh or used in cooking, particularly in sweet desserts. One of the most common desserts with the pecan as a central ingredient is the pecan pie, a traditional Southern U.S. dish. Pecans are also a major ingredient in praline candy.

In addition to the pecan seed, the wood is also used in making furniture and wood flooring as well as flavoring fuel for smoking meats.

Quercus stellata (Post oak) is an oak in the white oak section. It is a small tree, typically 10–15 m tall and 30–60 cm trunk diameter, though occasional specimens reach 30 m tall and 140 cm diameter. It is native to the eastern United States, from Connecticut in the northeast, west to southern Iowa, southwest to central Texas, and southeast to northern Florida. It is one of the most common oaks in the southern part of the eastern prairies, such as in the Cross Timbers.

The leaves have a very distinctive shape, with three perpendicular terminal lobes, shaped much like a Maltese Cross. They are leathery, and tomentose (densely short-hairy) beneath. The branching pattern of this tree often gives it a rugged appearance. The acorns are 1.5–2 cm long, and are mature in their first summer.

The name refers to the use of the wood of this tree for fence posts. Its wood, like that of the other white oaks, is hard, tough and rot-resistant. This tree tends to be smaller than most other members of the group, with lower, more diffuse branching, largely reflecting its tendency to grow in the open on poor sites, so its wood is of relatively low value as sawn lumber. It is also a popular wood for smoking Texas barbecue.

Koelreuteria paniculata is a species of flowering plant in the family Sapindaceae, native to eastern Asia, in China and Korea. Common names include goldenrain tree, pride of India, China tree, or varnish tree.

It is a small to medium-sized deciduous tree growing to 7 m (23 ft) tall, with a broad, dome-shaped crown. The leaves are pinnate, 15–40 cm (6–16 in) long, rarely to 50 cm (20 in), with 7-15 leaflets 3–8 cm long, with a deeply serrated margin; the larger leaflets at the midpoint of the leaf are sometimes themselves pinnate but the leaves are not consistently fully bipinnate as in the related Koelreuteria bipinnata.

The flowers are yellow, with four petals, growing in large terminal panicles 20–40 cm (8–16 in) long. The fruit is a three-parted inflated bladderlike pod 3–6 cm long and 2–4 cm broad, green ripening orange to pink in autumn, containing several dark brown to black seeds 5–8 mm diameter.

Platanus occidentalis, also known as American sycamore, American planetree, occidental plane, and buttonwood, is one of the species of Platanus native to North America. It is usually called sycamore in North America, a name which can refer to other types of tree in other parts of the world.

An American sycamore tree can often be easily distinguished from other trees by its mottled exfoliating bark which flakes off in great irregular masses, leaving the surface mottled, and greenish-white, gray and brown. The bark of all trees has to yield to a growing trunk by stretching, splitting, or infilling; the sycamore shows the process more openly than many other trees. The explanation is found in the rigid texture of the bark tissue which lacks the elasticity of the bark of some other trees, so it is incapable of stretching to accommodate the growth of the wood underneath, so the tree sloughs it off.

The sycamore tree is often divided near the ground into several secondary trunks, very free from branches. Spreading limbs at the top make an irregular, open head. Roots are fibrous. The trunks of large trees are often hollow.

Another peculiarity is the way the leaves grow sticky, green buds. In early August, most trees in general will have—nestled in the axils of their leaves—the tiny forming bud which will produce the leaves of the coming year. The sycamore branch apparently has no such buds. Instead there is an enlargement of the petiole which encloses the bud in a tight-fitting case at the base of the petiole.

Cornus drummondii, commonly known as the Roughleaf Dogwood, is a small deciduous tree that is native primarily to the Great Plains and Midwestern regions of the United States. It is also found around the Mississippi River. It is uncommon in the wild, and is mostly found around forest borders. The roughleaf dogwood is used as a buffer strip around parking lots, in the median of highways and near the decks and patios of homes. It can grow to a height of 15 to 25 feet (4.6 - 7.6 m) with a spread of 10 to 15 feet (3.1 - 4.6 m).

The roughleaf dogwood flowers during the summer months. It produces off-white four-petaled open flowers that are followed by small white fruits that ripen from August to October. These dogwoods can form a dense thicket that is used as a hedge, border or cover for wildlife. At least forty species of birds are known to feed on the fruits of the Roughleaf Dogwood.

Viburnum prunifolium (known as blackhaw or black haw, blackhaw viburnum, sweet haw, and stag bush) is a species of Viburnum native to northeastern North America, from Connecticut west to eastern Kansas, and south to Alabama and Texas.

It is a deciduous shrub or small tree growing to 2–9 m tall with a short crooked trunk and stout spreading branches; in the northern parts of its range, it is a shrub, becoming a small tree in the southern parts of its range. The bark is reddish-brown, very rough on old stems. The branchlets are red at first, then green, finally dark brown tinged with red. The winter buds are coated with rusty tomentum. The flower buds ovate, 1 cm long, much larger than the axillary buds. The leaves are simple, up to 9 cm long and 6 cm broad, oval, ovate or orbicular, wedge-shaped or rounded at base, serrate, acute, with serrated edges with a grooved and slightly winged red petiole 1.5 cm long; they turn red in fall. The leaves are superficially similar to some species of Prunus (thus "prunifolium"); they come out of the bud involute, shining, green, tinged with red, sometimes smooth, or clothed with rusty tomentum; when full grown dark green and smooth above, pale, smooth or tomentose beneath.

The flowers are creamy white, 9 mm diameter; the calyx is urn-shaped, five-toothed, persistent; the corolla is five-lobed, with rounded lobes, imbricate in bud; the five stamens alternate with the corolla lobes, the filaments slender, the anthers pale yellow, oblong, two-celled, the cells opening longitudinally; the ovary is inferior, one-celled, with a thick, pale green style and a flat stigma and a single ovule. The flowers are borne in flat-topped cymes 10 cm in diameter in mid to late spring. The fruit is a drupe 1 cm long, dark blue-black with glaucous bloom, hangs until winter, becomes edible after being frosted, then eaten by birds; the stone is flat and even, broadly oval. Wherever it lives, black haw prefers sunny woodland with well-drained soil and adequate water.

Quercus shumardii, the Shumard oak, spotted oak, Schneck oak, Shumard red oak, or swamp red oak, is one of the largest of the oak species in the red oak group (Quercus section Lobatae). It is closely related to Texas red oak (Quercus buckleyi), Nuttall's oak (Quercus texana), and Chisos red oak (Quercus gravesii).

Mature Shumard oak typically reach heights of 25 to 35 meters (82 to 115 ft), trunk diameter is typically 60 to 100 centimeters (24 to 39 in), and crown width typically reaches 12 to 18 meters (39 to 59 ft) in width. Typical size varies according to region, with larger specimens occurring in the southern portions of its native range in the United States. Record Shumard oaks have been measured at up to 42 meters (138 ft) tall, with crowns up to 27.5 meters (90 ft) in width. Young specimens generally exhibit conic or ovate crowns, with the upper crown filling in as the tree reaches maturity. Trunks are relatively straight and vertical. Trunks may have deeply fluted buttresses near the ground. Shumard oak is typically found in lowland areas and is able to survive where the soils experience flooding for six weeks of the year.

The young bark of the Shumard oak is light grey, very smooth, and very reflective. Shumard oak bark darkens and develops ridges and furrows as it ages. There are occasionally white splotches on the bark.

Shumard oak twigs terminate in a cluster of buds. The buds are lighter in color than the olive-green twigs. The young twig is highly reflective. Shumard oak bears relatively large acorns, which typically reach up to 3 centimeters (1 in) in diameter. Acorns take between 1.5 and 3 years to fully mature, and may go unnoticed during their early stages of development.

The acorns of the Shumard oak provide food for various songbirds, game birds such as wild turkey and quail, waterfowl, white-tail deer, feral hogs, and various rodents such as squirrels. The leaves and twigs can also provide browse for white-tail deer.

Quercus falcata, commonly known as the southern red oak or Spanish oak, is a tree in the red oak section (Lobatae) of the genus Quercus native to the southeastern United States.

It is a medium-sized deciduous tree reaching 25–30 m tall, rarely 35–38 m (forest grown specimens on highly productive sites), with a trunk up to 11⁄2 meters in diameter, the crown with a broad, round-topped head. The leaves are 10–30 cm long and 6–16 cm wide, with 3 to 5 sharply pointed, often curved, bristle-tipped lobes, the central lobe long and narrow; the small number of long, narrow lobes is diagnostic, readily distinguishing Southern Red Oak from other red oaks. The base of the leaf is distinctly rounded into an inverted bell shape and often lopsided. They are dark green and shiny above, and rusty and hairy below, particularly along the midrib and veins. The seed is a short acorn 9–16 mm long, bright orange-brown, enclosed for one-third to half of its length in a flat cup. The acorn matures at the end of its second season. The bark is dark brownish gray with narrow, shallow ridges.

Southern red oak has been reported to form occasional hybrids with several other red oaks in the region.

Celtis laevigata is a medium-sized tree native to North America. Common names include Sugarberry, Southern Hackberry, or in the southern U.S. Sugar Hackberry or just Hackberry.

Sugarberry is easily confused with Common Hackberry, (C. occidentalis) where the range overlaps. Sugarberry has narrower leaves which are smoother above. The species can also be distinguished by habitat: where the ranges overlap, Common Hackberry occurs primarily in upland areas, whereas Sugarberry occurs mainly in bottomland areas.

Sugarberry's range extends from the Eastern United States west to Texas and south to northeastern Mexico. It is also found on the island of Bermuda. Sugarberry mixed with hackberry supplies the lumber known as hackberry. Small amounts are used for dimension stock, veneer, and containers, but the main use of sugarberry wood is for furniture. The light-colored wood can be given a light- to medium-brown finish that in other woods must be achieved by bleaching. The wood is also used to produce sporting goods and plywood.

Sugarberry is frequently planted as a shade-tree within its range. It is well-adapted to urban areas; its elm-like shape and warty bark make it an attractive landscape tree.

Liquidambar styraciflua, commonly called American sweetgum, sweetgum, sweet gum, sweet-gum (sweet gum in the UK), hazel pine, American-storax, bilsted, red-gum, satin-walnut, star-leaved gum, or alligator-wood is a deciduous tree in the genus Liquidambar native to warm temperate areas of eastern North America and tropical montane regions of Mexico and Central America. Sweet gum is one of the main valuable forest trees in the southeastern United States, and is a popular ornamental tree in temperate climates. It is recognizable by the combination of its five-pointed star-shaped leaves and its hard, spiked fruits. It is currently classified in the plant family Altingiaceae, but was formerly considered a member of the Hamamelidaceae.

Liquidambar styraciflua is a medium-sized to large tree, growing anywhere from 33–50 feet (10–15 m) in cultivation and up to 150 feet (46 m) in the wild, with a trunk up 2–3 feet (0.61–0.91 m) in diameter, on average. Trees may live to 400 years. The tree is a symmetrical shape and crowns into an egg shape when the branches get too heavy after its first two years of cultivation.

Another distinctive feature of the tree is the peculiar appearance of its small branches and twigs. The bark attaches itself to these in plates edgewise instead of laterally, and a piece of the leafless branch with the aid of a little imagination readily takes on a reptilian form; indeed, the tree is sometimes called Alligator-wood. The bark is a light brown tinged with red and sometimes gray with dark streaks and weighs 37 lbs. per cubic foot. It is deeply fissured with scaly ridges. The branches carry layers of cork. The branchlets are pithy, many-angled, winged, and at first covered with rusty hairs, finally becoming red brown, gray or dark brown. As an ornamental tree, the species has a drawback—the branches may have ridges or "wings" that cause more surface area, increasing weight of snow and ice accumulation on the tree. However, the wood is heavy and hard with an interlocking grain, but is difficult to season.

The leaves usually have five (but sometimes three or seven) sharply pointed palmate lobes. They are 3-5 inches wide on average and have three distinct bundle scars.

The flowers typically appear in March to May and persist into Autumn, sometimes persisting into the Winter. They are typically about 1–1.5 inches in diameter and are covered with rusty hairs. The flowers are unisexual and greenish in color. Staminate flowers in terminal racemes two to three inches long, the pistillate in a solitary head on a slender peduncle borne in the axil of an upper leaf. Staminate flowers destitute of calyx and corolla, but are surrounded by hairy bracts. Stamens indefinite; filaments short; anthers introrse. Pistillate flowers with a two-celled, two-beaked ovary, the carpels produced into a long, recurved, persistent style. The ovaries all more or less cohere and harden in fruit. There are many ovules but few mature.

The distinctive compound fruit is hard, dry, and globose, 1–1.5 inches in diameter, composed of numerous (40-60) capsules. Each capsule, containing one to two small seeds, has a pair of terminal spikes (for a total of 80-120 spikes). When the fruit opens and the seeds are released, each capsule is associated with a small hole (40-60 of these) in the compound fruit.

Triadica sebifera, also known as Sapium sebiferum, is commonly known as the Chinese tallow tree, Florida aspen, chicken tree, gray popcorn tree, and candleberry tree. The tree is native to eastern Asia, and is most commonly associated with eastern China, Taiwan, and Japan. In these regions, the waxy coating of the seeds is used for candle and soap making, and the leaves are used as herbal medicine to treat boils. The plant sap and leaves are reputed to be toxic, and decaying leaves from the plant are toxic to other species of plant. The specific epithets sebifera and sebiferum mean "wax-bearing" and refer to the vegetable tallow that coats the seeds.

It is useful in the production of biodiesel because it is the third most productive vegetable oil producing crop in the world, after algae and oil palm. This species is considered to be a noxious invader in parts of the southern U.S.

The simple, deciduous leaves of this tree are alternate, broad rhombic to ovate in shape and have smooth edges, heart shaped and sometimes with an extended tail often resembling the bo tree, Ficus religiosa. The leaves are bright green in color and slightly paler underneath. They become bright yellows, oranges, purples and reds in the autumn. The tree is monoecious, producing male and female flowers on the same plant.

The waxy green leaves set off the clusters of greenish-yellow and white flowers at bloom time. The flowers occur in terminal spike-like inflorescences up to 20 cm long. Light green in color, these flowers are very conspicuous in the spring. Each pistillate (female) flower is solitary and has a three-lobed ovary, three styles, and no petals. They are located on short branches at the base of the spike. The staminate (male) flowers occur in clusters at the upper nodes of the inflorescence.

Fruits are three-lobed, three-valved capsules. As the capsules mature, their color changes from green to a brown-black. The capsule walls fall away and release three globose seeds with a white, tallow-containing covering. Seeds usually hang on the plants for several weeks. In North America, the flowers typically mature from April to June and the fruit ripens from September to October.

Quercus nigra, the water oak, is an oak in the red oak group (Quercus sect. Lobatae), native to the southeastern United States, from southern Delaware and south to the coastal areas of Maryland, Virginia, the piedmont of North Carolina, all of South Carolina, most of Georgia (with the exception of the Appalachian Mountains), all of Alabama, Mississippi, central Florida, and westward to Louisiana and eastern Texas. From there, northward to southeastern Missouri including Arkansas, eastern Oklahoma, parts of Tennessee, and extreme southwestern Kentucky. It occurs in lowlands and up to 450 m (1500 ft) altitude.

It is a medium-sized deciduous tree, growing to 30 m (100 ft) tall with a trunk up to 1 m (3 ft) in diameter. Young trees have a smooth, brown bark that becomes gray-black with rough scaly ridges as the tree matures. The leaves are alternate, simple and tardily deciduous, only falling well into winter; they are 3–12 cm (1–5 in) long and 2–6 cm (1/2–2 in) broad, variable in shape, most commonly shaped like a spatula being broad and rounded at the top and narrow and wedged at the base. The margins vary usually being smooth to shallowly lobed, with a bristle at the apex and lobe tips. The tree is easy to identify by the leaves, which have a lobe that looks as if a drop of water is hanging from the end of the leaf. The top of each leaf is a dull green to bluish green and the bottom is a paler bluish-green. On the bottom portion of the leaves, rusty colored hairs run along the veins. The acorns are arranged singly or in pairs, 10–14 mm (1/3-1/2 in) long and broad, with a shallow cupule; they mature about 18 months after pollination in fall of second year.

Fraxinus americana (white ash or American ash) is a species of ash tree native to eastern and central North America. It is found in mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas. Isolated populations have also been found in western Texas, Wyoming and Colorado, and the species is reportedly naturalized in Hawaii.

The name White Ash derives from the glaucous undersides of the leaves. It is similar in appearance to the Green Ash, making identification difficult. The lower sides of the leaves of White Ash are lighter in color than their upper sides, and the outer surface of the twigs of White Ash may be flaky or peeling. Green Ash leaves are similar in color on upper and lower sides, and twigs are smoother. Despite some overlap, the two species tend to grow in different locations as well; White Ash is a forest tree that commonly occurs alongside Sugar Maple while Green Ash is a pioneer species that inhabits riparian zones and disturbed areas.

White ash is one of the most used trees for everyday purposes and, to keep up with high demand, is cultivated almost everywhere it can be. The wood is white and quite dense (within 20% of 670 kg/m3), strong, and straight-grained. It is the timber of choice for production of baseball bats and tool handles. The wood is also favorable for furniture and flooring. Woodworkers use the timber mainly for internal uses due to high perishability in contact with ground soil. It is also used to make lobster traps. Recently, it has also become a popular choice for solidbody electric guitar wood as well. It makes a very servicable longbow if properly worked. The wood was used in ceiling fan blades from the 1970s through the mid-1980s, though cane was sometimes simulated with plastic then. It is no longer used for ceiling fan blades in most countries.

Quercus phellos (willow oak) is a deciduous tree in the red oak group of oaks. It is native to eastern North America from southern New York (Long Island) south to northern Florida, and west to southernmost Illinois and eastern Texas. It is most commonly found growing on lowland floodplains, often along streams, but rarely also in uplands with poor drainage, up to 400 m altitude.

It is a medium-sized tree growing to 20–30 m (65–98 ft) tall (exceptionally to 39 m/128 ft), with a trunk up to 1–1.5 m (3.3–4.9 ft) diameter (exceptionally 2 m/6.6 ft). It is distinguished from most other oaks by its leaves, which are shaped like willow leaves, 5–12 cm long and 1–2.5 cm broad with an entire margin; they are bright green above, paler beneath, usually hairless but sometimes downy beneath. The fruit is an acorn, 8–12 mm long, and almost as wide as long, with a shallow cup; it is one of the most prolific producers of acorns, an important food tree for squirrels, birds, and other animals in the forest. The tree starts acorn production around 15 years of age, earlier than many oak species.

Willow oaks can grow moderately fast (height growth up to 60 cm / 2 feet a year), and tend to be conic to oblong when young, rounding out and gaining girth at maturity (i.e. more than 50 years).
