Caralluma keithii R.A.Dyer
Keith's Caralluma
A species described by Robert Allen Dyer from material collected in the former South African Transvaal (now Gauteng and Limpopo provinces). Named in honour of Keith, probably a collector or botanist associated with exploration of the region. A medium-sized quadrangular-stemmed succulent typical of arid scrublands and rocky areas of the South African bushveld. Flowers follow the typical southern African caralluma pattern: five dark-coloured lobes with fetid odour.
