The genus Dinteranthus occurs in the northwestern parts of the Northern Cape Provice, South Africa and the southeastern parts of Namibia. The small sphaeroid bodies of these plants resemble other rock-like mesembs such as Lithops. The leaf pairs are separated by a deep cleft from which the flower arises. Unlike other sphaeroids, however, the leaves often have a distinct keel along the lower leaf surface. The plants are popular among collectors. They need excellent drainage and a good deal of light. They should be treated like Lithops, though they require less water. They are propagated by seed.
