Ipomoea acanthocarpa (Choisy) Asch. & Schweinf.

Beitr. Fl. Aethiop.: 277, 1867

A species widely distributed in South America, where it extends in an arc from Bolivia through Peru to southern Colombia and then eastwards to Guyana and north east Brazil where it is especially common. There is an isolated record from Costa Rica. In the Old World it follows an essentially Sahara-Sindian distribution. Ipomoea piurensis, previously considered a different species, is now treated as part of I. acanthocarpa.

Our molecular studies indicate that the species is most likely of American origin and it would have subsequently travelled across the Atlantic by natural means.
