Ceropegia insignis R.A.Dyer
Status and Criteria
|N. Hahn & L. von Staden|
|A range-restricted species (EOO 164 km²), occurring at two to three locations and declining due to ongoing habitat loss and degradation.|
|South African endemic|
|Limpopo, North West|
|Northern North West province and adjacent areas in Limpopo between Ramotswa and Dwaalboom. It possibly also occurs in adjacent areas in Botswana.|
Habitat and Ecology
|Dwarsberg-Swartruggens Mountain Bushveld, Dwaalboom Thornveld|
|Stony slopes and sandy soils in grassland and open savanna.|
|Field observations at the type locality indicate that the habitat is severely degraded due to overgrazing, erosion and bush encroachment (Hahn 2013). In Limpopo Province it is threatened by ongoing habitat loss to crop cultivation.|
This species is known from only a few collections, and was last recorded in 1995. There are two disjunct subpopulations, and it is possible that others may exist in the area in between, which is remote and botanically poorly explored. Surveys of the type locality failed to relocate the subpopulation (Hahn 2013). The habitat is very degraded and it may be locally extinct in this area.
