Status and Criteria
Data Deficient - Insufficient Information
Assessment Date
L. von Staden
A rare, range-restricted and very poorly known species last recorded in the wild in 1940. It is too poorly known to assess its risk of extinction, but is possibly threatened or even extinct.
South African endemic
Provincial distribution
Western Cape
Mountains between Villiersdorp and Genadendal.
Habitat and Ecology
Major system
Major habitats
Sandstone slopes above 1000 m.
This species appears to be extremely rare, and it has not been recorded in the wild in more than 70 years. The population has possibly declined - Hall et al. (1980) thought that it is extinct - but the reasons for decline is not known. Montane fynbos habitat is still intact across this species' range. Possibly it may have been affected by too frequent fire.

This species is known from only a few collections and was last recorded in the wild in 1940. Wildepaardeberg on the northern slopes of Jonaskop in the Riviersonderend Mountains is botanically very well explored, but there has been no recent collections. Staavia is taxonomically problematic, and it is possible that this species may be overlooked and misidentified as other species. It is also likely that subpopulations are very small, localized and easily overlooked.
