Dogbane

Dogbane (Apocynum), a small north temperate genus of Apocynaceæ, perennial herbs or undershrubs. The Dogbane of North America (A. androsaemifolium), often called Fly-trap, from the throat appendages of its corolla closing upon the flies which enter it, is of medicinal repute; similarly also its congener A. cannabinum, or Canadian Hemp. See APOCYNACEÆ.
