Centrosema, the butterfly peas,[1] is a genus of (mainly tropical) American vines in the legume family (Fabaceae). Species include:
- Centrosema angustifolium Benth.
- Centrosema arenarium Benth.
- Centrosema brasilianum (L.) Benth.
- Centrosema dasyanthum Benth.
- Centrosema macranthum Hoehne
- Centrosema macrocarpum
- Centrosema plumerii (Turp. ex Pres.) Benth.
- Centrosema pubescens Benth.
- Centrosema sagittatum (Willd.) Brad.
- Centrosema vexillatum Benth.
- Centrosema virginianum
Lepidopteran caterpillars that feed on butterfly peas include the Two-barred Flasher (Astraptes fulgerator), occasionally recorded on C. macrocarpum and C. plumieri at least.[2]
Another plant referred to as butterfly pea from the same subtribe Clitoriinae is the related Clitoria ternatea. However it doesn't belong to the genus Centrosema.
