Kalanchoe waterbergensis is described from the western Waterberg margin, just east of Thabazimbi and south of the Kransberg and Marakele National Park (Limpopo Province). Kalanchoe waterbergensis is a distinct succulent from the quartzitic sandstone soils growing on gravelly slopes and rocky terrain in savanna. It differs from Kalanchoe rotundifolia by its glaucous leaves which are auriculate at the base and leaf orientation as well as floral features.
