|sumac (Rhus spp.)||
sumac (Rhus spp.; CASHEW FAMILY [Anacardiaceae]) Five 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 clusters at the end of branches. Our most common species, staghorn sumac, typically occurs on shallow soils.
