Justification:
Although still relatively abundant in some parts of its range, some of the subpopulations have been almost entirely eliminated (e.g. at Elizabethville in Zimbabwe). The uncertain taxonomic status of these subpopulations raises the risk associated with local extinction of some subpopulations due to the impacts of collectors who are keen to have these potentially "new" species in their collections. Listed as Vulnerable on the basis of at least a 30% population decline in the past three generations (mostly in the last 50 years).
History:
2003 Vulnerable (IUCN 2003)
2003 Vulnerable
1997 Rare (Walter and Gillett 1998)

Geographic Range [top]

Range Description: This species occurs in Zimbabwe and Mozambique, where most of the plants are found in the highlands of the Mapande Range. In the south from Mount Selinda in Zimbabwe northwards through the Chipinge area , near Mount Nyanyadzi, along the Odzi and Garezi rivers and on to Mount Gorongo (incorrectly named Mount Gorongowe in the literature) and further north to Mount Darwin (Pfura/Fura). The type locality is the Numkwarara (Nyamkwarara) Valley near Mount Gorongo. In Mozambique plants are found near Garuso, Mount Bandula, Mount Chicamba, near Vanduzi and Mount Chinhazanza (Chinyayadze/Chinyazange) near the Pungwe (Pungoe/Pungue) river. Recorded from 600 to 1,400 m asl.

There is considerable variation between populations from different sites and this has raised questions about the taxonomy of these populations. Capela (2006) argues that there could be as many as five species but taxonomists have not been able to discern consistent characters to define these possible species.
