Calotesta is a monotypic genus of flowering plants in the family Asteraceae, containing the single species Calotesta alba. It is endemic to the Western Cape of South Africa , where it is limited to the Klein Swartberge Mountains.[1]
This plant is characterized by the thick, cutinized coating on its seeds.[2] When the species was described in 1990, it fit into no existing genera, so the new genus Calotesta was erected to house it.[3]
The plant grows on steep sandstone cliff faces in the fynbos.[1]
It is designated a critically rare taxon in South Africa because it is limited to a single mountain range, but it is not considered to be a threatened species.[1]
