Sutherlandia

Sutherlandia, known as Ballonerbsen in German, is a genus of flowering plants in the family Fabaceae containing 6 known living species. The genus was once organized as having a single species, S. frutescens, but later expanded to include more based on morphological charecteristics. However, later analysis found more genetic variation between populations than between taxa.[1]

The genus Sutherlandia is sometimes included in the genus Lessertia and it is morphologically and chemically similar to Lessertia, Astragalus, and other genera of the tribe Galegeae.[2]
