Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Haevermans, T.
Reviewer(s): Rajeriarison, C., Labat, J.N., Lowry, P. & Randrianjohany, E. (Madagascar Plants RLA)
Justification:
Both varieties are listed as threatened, and although var ankaratrae is listed as Vulnerable (this is probably an under lisiting), the species as a whole is considered Endangered. This is because the combined extent of occurrence is < 5,000 km² and the combined area of occupancy is < 500 km². The number of locations is certainly less than five and the range is severely fragmented. There is continuing decline due to habitat loss and degradation.
