Corpuscularia

About

Delosperma is a genus of around 170 species of succulent plants, formerly included in Mesembryanthemum in the family Aizoaceae. It was defined by English botanist N. E. Brown in 1925. The genus is common in southern and eastern Africa, with a few species in Madagascar, Reunion island, Yemen and Saudi Arabia. Delosperma species, as do most Aizoaceae, have hygrochastic capsules, opening and closing as they wet and dry.
