Ptelea (tele a)

[NL. (Linnæus, 1737), so called from the similarity of the fruit to that of the elm; two or three cells, each one-seeded. The 8 species are all natives of North America. They are shrubs or small trees, with bitter bark, bearing alternate compound leaves of two or rarely five leaflets, which are broad and punctate with pellucid dots. The yellowish-green flowers are followed by rather large clusters of dry and flat disk-like fruit, with veiny wings. P. trifoliata is the hop-tree, known also as wingseed (from the fruit), wafer - ash, and shrubby Ptenoglo a (te-no-glos'ä), n. pl. [NL., row.
