Justification
A rare endemic (EOO<40 km², AOO<10 km²), from the eastern escarpment in Mpumalanga. Occurs as scattered subpopulations along three streams in the Dullstroom-Lydenburg area. All of these stream systems are invaded by alien wattles which are causing ongoing degradation of the habitat. We estimate that between 500 and 1000 mature individuals exist, no subpopulation is larger than 250 individuals.
