Greyia is a genus of plant in family Melianthaceae. It contains three species: \n* Greyia flanaganii, Bolus \n* Greyia radlkoferi \n* Greyia sutherlandii Unlike other members of the Melianthaceae, Greyia has simple (undivided) 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 of classification, it is included in the Melianthaceae.
