description_en: Genus of about 20 species of very variable, perennial succulents from low hillsides in Saudi Arabia, Oman, Yemen, and tropical E. Africa and South Africa. They have branching, prostrate to erect, spherical to short-columnar stems, each with 6- to 20-angled, dark green ribs, usually divided into hexagonal tubercles. Tiny, grey-green leaves are short-lived, sometimes persisting as white spines on the tubercles. Saucer- to bell-shaped, 5-lobed, fleshy flowers, with whorled, cup-shaped corollas, are borne in clusters, mainly at the stem tips. In frost-prone areas, grow as houseplants or in a warm greenhouse; in warm, dry climates, grow outdoors in a border with other succulents.

hardiness_en: Frost tender.
