Assessment Information [top]

Red List Category & Criteria: Critically Endangered A4acd; B2ab(iii,iv,v); C1 ver 3.1
Year Published: 2010
Date Assessed: 2009-10-31
Assessor(s): Donaldson, J.S.
Reviewer(s): Agenbag, L. & Bösenberg, J.D.
Justification:
The original population (at the time of description) was estimated at 400-500 plants. In 2004, only 219 plants were found in two localities as part of helicopter surveys, with most of the plants occurring in one site. Stan Rogers (pers. comm.) from the Limpopo Provincial government reported in 2006 that ground rangers could not locate these plants and that they may also be gone. This has yet to be confirmed. The area of occupancy for the remaining plants was small - estimated to be only about 5 km².
History:
2003 Critically Endangered (IUCN 2003)
2003 Critically Endangered
1997 Vulnerable (Walter and Gillett 1998)
