Thunberg found this species in Oudshorn Diy.; in the Karoo behind Attaqu 
Kloof, in Vanrhynsdorp Div., between Olifants River and the Bokke Velde ‘i 
Calvinia Div., at Hantam, and in Sutherland Div., on the Rogge Veldt Nek 
Thunberg’s plant may have been D. radicans, Nees, or one of the other closely 
allied species. The example of Wood, 4967, at the British Museum is Asystasia
