²). This species is known from a small area on the northern section of the summit of Vyftienmyl-se-Berg, an inselberg that is home to many local endemics. As there are no severe threats, the population is not likely to be declining. As its habitat is well-protected and the species is not in danger of extinction, it is given a status of Critically Rare (L. von Staden, pers. comm.).
