Rhus spp.; sumac
[Anacardiaceae]
Seven species of tall shrubs or small, short lived trees with stout,
hairy stems bearing long (12-24"), alternate, compound leaves with odd
numbers (11-31) of lance shaped toothed leaflets.
The foliage turns bright scarlet in the fall.
Enormous numbers of tiny flowers produce tiny fruits (1/8" in
diameter) in conspicuous, dense, reddish clusters at the end of
branches. Our most common
species,
R. hirta (staghorn sumac),
typically occurs on shallow soils.
