Assessor(s) | D. Raimondo & T. Patel |
Justification | This is a poorly known species recorded from old collections. In 2010, one new subpopulation was discovered. Old herbarium records indicate that it occurs in heavily populated areas of the former Transkei in the Eastern Cape and is highly likely to be threatened by afforestation, livestock overgrazing and associated soil erosion. It is listed as Data Deficient - Insufficient Information, as not much is known about this species in recent records. More fieldwork is required to determine this species' distribution, habitat and population structure and trends. |
