Kewa

Kewa is a genus of flowering plants, consisting of eight species of succulent sub-woody plants, native to eastern and southern Africa, including Saint Helena and Madagascar. These are small shrubs or herbs that form cushions and have edible, acid-tasting leaves. Kewa is the only genus in the family Kewaceae. The species were formerly included in the genus Hypertelis of the family Molluginaceae, but molecular studies have shown that most species did not belong there, but were rather distantly related to Molluginaceae, being placed in a clade comprising Aizoaceae, Gisekiaceae and Barbeuiaceae. Only the type species Hypertelis spergulacea remains in Molluginaceae; all others are transferred to the genus Kewa, which was named for Kew, where the Royal Botanic Gardens, Kew are situated....read more on Wikipedia.
