Deciduous shrubs and woody vines that often bear male and female flowers on separate plants, and have well-developed resin canals in the bark and often elsewhere; includes Sumac and Poison Ivy, as well as some familiar tropical food plants like Cashew. The The resin is clear when fresh but drying black, and, in some species, can cause dermatitis.
Flowers in clusters, small, regular, often unisexual. Flowers upright and crowded at the tips or sides of branches, or more loosely arranged where the leaves join the stem (axils). Petals 5, usually separate, smooth to hairy. Sepals 5, generally fused below. Stamens 5 to 10, if 5, then usually alternating with the petals. Carpels 3; styles separate or united; ovary chambered but usually with only one chamber developed. A prominent nectar ring that sometimes has 5 lobes is located between the stamens and ovary. Plants produce berry-like stone fruits (drupes), that may be red and hairy, or greenish-white to yellowish and smooth.
Leaves alternate and spiral, usually with saw-toothed edges, turning vivid colours (red, orange and or yellow) in the Fall. Compound leaves with 3 or more leaflets, protruding from both sides of the main leaf stem. Stipules absent.
Plants upright, or climbing or trailing without tendrils; climb by roots on the stems.

Roadsides, open areas on sandy or rocky soils

Root system shallow, wide-spreading. Aggressively spreads by suckers. Flowers small, greenish-yellow in large, dense erect clusters at the tip of a shoot. Pollen flowers in clusters about 30 cm long; seed flowers in smaller clusters, generally on separate trees. Appear in July after the leaves are fully developed.

Remain on tree throughout most of the winter. Compound leaves are divided into 11-31 lance-shaped leaflets on a a central stalk. Each leaflet 5-12 cm long; central ones largest, curved, long-pointed, sharply toothed, almost stalkless; upper surface dark green; paler beneath, with fine hairs on the midvein and lateral veins; bright scarlet or orange in autumn. No terminal bud. Lateral buds rounded, 5-7 mm long, covered with long pale brown hairs. Leaf scars crescent-shaped, almost encircling the bud with 3 groups of vein scars. Bark thin, smooth, dark yellowish-brown with prominent lenticels, becomes scaly with age. Twigs densely covered with dark velvety hairs, exude a milky sap if broken. Growth resumes each year from 1-3 lateral buds some distance below the dead tip creating a distinctive branching effect. Pith large, yellowish-brown.
