So7ne New South African Succulents and other Plants. Part IV. 239 
lutea sed carina et vexilli apex sericese. Ovarium bi-ovulatum. Legumen 
lineare, acuminatum, seminibus duobus. 
This plant has the appearance of a Rafnia, but on account of the 
structure of the ovary and the silky corolla it must be placed into the 
genus Borhonia. Here it does not fit into either of the tv^o groups formed 
by Harvey in the Flora Capensis, for only the alae are glabrous. 
The plant is of special interest, as it supplies the " Vooibosh-tea,' 
which is now so largely used in South Africa either under this name or as 
naald-thee " or " koopmans-thee." The shrublet occurs apparently only 
-on the Cedar Mountains near Clanv^illiam and Wupperthal.
