Greyia is a genus of plant in family Melianthaceae.

Unlike other members of the Melianthaceae, Greyia has simple (undivided) leaves, flowers with ten stamens, and ovaries with parietal placentation.[1] 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.


Standard Cyclopedia of Horticulture

Greyia (after Sir George Grey, once Governor of Cape Colony). Often spelled Greya. Melianthacea. A small tree from Natal, which bears large spikes of pendulous, five-petaled, scarlet flowers, and is cultivated outdoors in southern California and abroad under glass in many botanic gardens.

Species probably 3, but only 1 appears to be in cult. in R.H. 1894:252 this plant is shown at its best, with a spike 6 in. long and 2-3 in. wide, containing probably over 100 fls., each ¾ in. across. In France this tree flowered from the end of autumn throughput the winter. The long-exserted stamens with reddish purple anthers make a striking feature. The structure of the fls. is so peculiar that Harvey referred the genus doubtfully to the saxifrage family. In European greenhouses, Greyia is a shrub requiring full sunlight, thorough ripening of the wood and a season of rest before flowering. In Natal it flowers in Aug. or Sept.. which is early spring there. Europeans recommend a sandy loam. Prop, by seeds or by cuttings from half- ripened wood. CH
