Cajanus kerstingii

About

Cajanus kerstingii is a widely ignored shrub found mostly in open savannah conditions across western Africa. It is closely related to the widely utilised Cajanus cajan, otherwise known as pigeon pea. Cajanus kerstingii can be consumed by humans as a cereal, pulse, fibre or forage. Unfortunately, very little data exists for this plant, but "one may reasonably expect it to be of value".
