Ptelea trifoliata
Rutaceae

Leaves are trifoliately compound, alternate and deciduous with ovate, glandular leaflets that stink when crushed. Twigs are red-brown with lenticels. Bark is brown-gray and smooth with lenticels, becoming scaly on larger trees. Flowers are in white terminal clusters (this species is dioecious). Fruit is a round hop-like samara. Form is a shrub or a small tree that grows up to 8 m (25 ft) in height and is found on a variety of sites in the southeast and central U.S. The fruits were reported to have been used as a substitute for hops in beer-making.
