Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2d; C1 ver 3.1
Year Published: 2010
Date Assessed: 2009-10-31
Assessor(s): Donaldson, J.S.
Reviewer(s): Agenbag, L. & Bösenberg, J.D.
Based on numbers in collections and ongoing decline in the wild, it is estimated that >80% of the plants have been removed from the wild in the past 90 years (three generations). The small overall population size and ongoing decline of ca. 30% over the next 30 years (one generation). Meeting both these requirements means that this species qualifies for listing as Critically Endangered under criteria A2 and C1.
2003 Critically Endangered
