Etymology: barbatus (lat.) - bearded
Distribution: South Africa (Eastern Cape, Western Cape, Northern Cape, Free State), Lesotho.
History: Huernia barbata was discovered by Francis Masson and described in 1796 as Stapelia barbata and Stapelia campanulata. Adrian Haworth transfered both to the genus Huernia and described new Huernia crispa in 1812. Stapelia clavigera, Stapelia tubata and Stapelia duodecimfida were described by Nicolaas Jacquin (1806). Haworth transfered S. tubata (1812) and S. clavigera (1819) to genus Huernia. S. duodecimfida was transfered to Huernia by Sweet (1830).
Alain White and Boyd Sloane recognized H. clavigera with var. maritima, H. barbata with var. griquensis and var. tubata and H. campanulata with var. denticoronata in 1937.
