Justification:
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.
