Greyia

Greyia is a genus of plant in family Francoaceae.
It contains three species native to South Africa, Eswatini, and Lesotho:

Unlike other plants sometimes included in the family Melianthaceae, Greyia has simple leaves, flowers with ten stamens, and ovaries with parietal placentation. Because of this, the genus has sometimes been placed in a separate family Greyiaceae, but under the APG [II system] and APG [III system] of classification, it was included in the Melianthaceae. Under the APG [IV system], it is included in the Francoaceae.
