Justification
Ceropegia stentiae is a rare and very poorly known species. Its EOO is estimated <1000 km², plants at two known locations continue to decline due to ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Limpopo
Range
Polokwane to Mookgophong.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Springbokvlakte Thornveld, Central Sandy Bushveld, Polokwane Plateau Bushveld
Description
Rocky outcrops and hill slopes in short, open sparse woodland.
Threats
This species is threatened by habitat loss to crop cultivation at Mookgophong, and urban expansion around Polokwane. Dyer (1980) states that Galpin indicated that the species was extremely rare due to the edible tubers being collected. It has possibly declined in rural areas due to plants being used for food.
Population

This species is known from only two disjunct subpopulations, and was last observed in 1993. There is ongoing habitat loss at both locations, and field surveys are urgently needed to relocate this species in the wild.


Population trend
Decreasing
Notes
Hahn (2013) reports this species as occurring near Wolmaransstad. It is possibly a misplaced locality, as the farm has the same name as the type locality near Mookgophong. The habitat at Wolmaransstad is very different from the habitat at Mookgophong and Polokwane, and Hahn's distribution is doubtful.
