Gonolobus Michaux. Subfamily: Asclepiadoideae. Common name: Anglepod.
A genus of about 120-140 species, herbaceous vines and lianas, primarily tropical. Liede (1997a), Lipow & Wyatt (1998), and others recognize Gonolobus as separate from Matelea.
ID notes: Matelea and Gonolobus are difficult to distinguish without flowers or fruits. Fresh Matelea leaves do not have a strong odor when crushed; Gonolobus leaves have a disagreeable odor of peanut butter or burnt-and-buttered popcorn. Gonolobus typically exhibits (at least some) leaves more drawn out in length with margins more or less parallel for some length before curving toward the tip (vs. in Matelea usually more rounded/ovate, curved throughout, and somewhat Ipomoea-like).
