Sours Arrica: without locality, cultivated specimens! 
Described from living plants. A specimen (Watermeyer in Herb, Pillans, 
1306) collected near Tsomo, in the Transkei, of which I have not seen flowers, 
may belong to this species.

teeth 14-2 lin. long, spreading, acute, slightly recurved at the 
tips; flowers from near the base of the young stems ; pedicels 
short, glabrous ; sepals 3-34 lin. long, narrowly lanceolate-attenuate, 
glabrous ; corolla apparently somewhat turbinate and flat- or broad- 
topped, with a short acute point, when expanded about 1} in. in
