Scientific Name | Xerophyta purpurascens Behnke |
Higher Classification | Monocotyledons |
Family | VELLOZIACEAE |
National Status |
Status and Criteria | Data Deficient - Taxonomically Problematic |
Assessment Date | 2014/05/19 |
Assessor(s) | L. von Staden & J.E. Burrows |
Justification | A poorly known species that is difficult to distinguish from Xerophyta villosa. More surveys are needed to better delineate the extent of the population as well as its relationship with X. villosa, and until then, its risk of extinction cannot be assessed. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Limpopo, Mpumalanga |
Range | Mountains north of Tzaneen, and the Drakensberg Escarpment south-east of Lydenburg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Grassland |
Description | Rocky, quartzite derived soils in montane grassland. |
Threats |
At both known locations, montane grasslands have been extensively modified to commercial timber plantations, and it is likely that this species has declined due to habitat loss in the past, and may continue to do so. One recent collection is from a well-managed private nature reserve, and this subpopulation is not threatened. The only other location is known from a very old record about 180 km further north, with imprecise locality information, and which may already be locally extinct due to habitat loss to plantations. |
Population |
This species is known from only two, highly disjunct locations. More surveys are needed to determine whether there are any subpopulations in the intervening areas, particularly in the Wolkberg Mountain range, where similar suitable habitat occurs. In the absence of good survey data on the size and extent of the population, this species' risk of extinction is difficult to assess.

Population trend | Unknown |
Notes |
This species is difficult to distinguish from X. villosa. Within Buffelskloof Nature Reserve, there are intermediate forms that cannot be easily assigned to either taxon (J.E. Burrows pers. comm. 2014). |
