Description of the genus

Dwarf tufted succulents, forming compact clumps, rarely slightly rhizomatous. Stems decumbent, obtusely angled, softly fleshy, smooth, glabrous to the naked eye. Leaves caducous leaving a whitish scar, subtended by a patch of stipular hairs. Inflorescence glabrous, 1 per stem, arising near base of the stem with 1-5 flowers developing in gradual succession on a stout gradually lengthening peduncle. Calyx 5-lobed. Corolla rotate to campanulate, usually lobed. Corona 2-seriate arising from the staminal column. Follicles slender, mottled with purple.

Comment: More recent phylogenetic evidence has led to the forming of a very broad concept of the genus Ceropegia including the genus Brachystelma and all known genera within the Stapeliae (Bruyns, P.V., Klak, C. & Hanáček, P., 2017). However we follow Goyder et Al. in Flora Zambesiaca 7(2), 2020 where the inclusion of the Stapeliad genera has not been accepted.
