This plant is a rhizomatous vine with climbing, branching stems that grow up to 8 meters long. Many of the branches are covered in prickles up to 9 millimeters long. The evergreen leaves are pale green, sometimes with white blotches, and are variable in shape. The inflorescence is an umbel of up to 15 or more pale green flowers. The fruit is a black berry just under a centimeter in length. It contains one seed. The plant reproduces by seed and by sprouting from its rhizome.

The leaves are alternate, 30–50 cm long, compound with 11-31 leaflets, each leaflet 5–11 cm long, with a serrated margin. The leaves turn scarlet in the fall. The flowers are tiny, green, produced in dense erect panicles 10–25 centimetres (3.9–9.8 in) tall, in the spring, later followed by large panicles of edible crimson berries that remain throughout the winter. The buds are small, covered with brown hair and borne on fat, hairless twigs. The bark on older wood is smooth and grey to brown.

Ulmus alata is most easily recognized by the very broad, thin pair of corky wings that form along the branchlets after a couple of years. The leaves are comparatively small for the genus, < 6.5 cm (2.5 in) long and < 2.0 cm (0.8 in) broad, oblong-lanceolate to narrowly elliptic, thin in texture, and smooth above.

The deciduous leaves of T. radicans are trifoliate with three almond-shaped leaflets. Leaf color ranges from light green (usually the younger leaves) to dark green (mature leaves), turning bright red in fall; though other sources say leaves are reddish when expanding, turn green through maturity, then back to red, orange, or yellow in the fall. The leaflets of mature leaves are somewhat shiny. The leaflets are 3–12 cm (1.2–4.7 in) long, rarely up to 30 cm (12 in). Each leaflet has a few or no teeth along its edge, and the leaf surface is smooth. Leaflet clusters are alternate on the vine, and the plant has no thorns. Vines growing on the trunk of a tree become firmly attached through numerous aerial rootlets. The vines develop adventitious roots, or the plant can spread from rhizomes or root crowns. The milky sap of poison ivy darkens after exposure to the air.

The bark is variable, usually dark gray-brown to pinkish-brown and scaly, but in some individuals, smooth and creamy pinkish-white, exfoliating in curly papery sheets. The twigs are glabrous or thinly hairy. The leaves are alternate, ovate, 4–8 cm (1.5–3 in) long and 3–6 cm (1.2–2.4 in) broad, with a serrated margin and five to twelve pairs of veins.

It is a medium-sized, deciduous tree growing to 15–30 meters tall and 12 meters wide. It has a trunk up to 1 m diameter, with brown to gray bark maturing into hard plates or ridges. The leaves are deciduous, opposite (or whorled), large, heart shaped, 20–30 cm long and 15–20 cm broad, pointed at the tip and softly hairy beneath. The flowers are 3–6 cm across, trumpet shaped, white with yellow stripes and purple spots inside; they grow in panicles of 10-30. The fruit is a long, thin legume-like pod, 20–40 cm long and 10–12 mm diameter; it often stays attached to tree during winter (and can be mistaken for brown icicles). The pod contains numerous flat, light brown seeds with two papery wings.

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 centimeters (20–31 in) diameter. The bark is dark brown to blackish, becoming fissured in older trees, and frequently forking near the base.[3] The shoots are slender and variable in color from green to brown, yellow or purplish.

Invasive species growing all along the bank Gin Creek. The leaves are opposite, 2–7 cm long and 1–3 cm broad, rarely larger, with an entire margin and a 2–8 mm petiole. The fruit is subglobose, 5–8 mm diameter.

The bark is mottled exfoliating which flakes off in great irregular masses, leaving the surface mottled, and greenish-white, gray and brown. The leaves are alternate, palmately nerved, broadly-ovate or orbicular.

The bark is dark in color, smooth, later scaly with ridges somewhat apparent, sometimes with maroon patches. Fruit is a legume. The leaves are Alternate, simple, heart-shaped or broadly ovate. Tree height approximately 12-15 ft. tall.

Fruit blue berries. Bark is reddish-brown, somewhat shaggy, and peels off in narrow strips. Tree is a coniferous evergreen. Leaves are arranged in opposite decussate pairs or occasionally whorls of three. Tree approximately 15-20 feet high.
