Population

This species was recently rediscovered at one of only two known localities in the Richtersveld, where it was last recorded in 1962. A small subpopulation of fewer than 100 mature individuals occurs on Cornells Kop. It also still occurs on the mountains above Numees Mine, where it is also localized (P.C.V. van Wyk pers. comm.).
