Description

Poison sumac is a shrub or small tree, growing up to nearly 9 metres (30 feet) in height. Each pinnate leaf has 7–13 leaflets, each of which is 5–10 centimetres (2–4 inches) long. These are oval-to-oblong; acuminate (tapering to a sharp point); cuneate (wedge-shaped) at the base; undulate (wavy-edged); with an underside that is glabrous (hairless) or slightly pubescent (down-like hair) beneath. The stems along the leaflets are red and the leaves can have a reddish tint to them, particularly at the top of the plant. New bark for a poison sumac tree is lightish gray, and as the bark ages, it becomes darker.
