Cape Province: probably on the Matroosberg, R. Marloth, 7949. 
This description is based on five specimens in Dr Marloth’s 
Herbarium, without exact particulars as to place or date of collection. 
Its nearest ally appears to be D. obtusifolia, Sonder (based on Drege, 
7144, Herb. Sonder, also without particulars as to place of collection, 
and not represented in S.A. Herbaria), from which it differs in its 
sparingly branching habit, the fleshy (never ovate) leaves without the 
rigid eiliolation of their margins and keels, the flowers often in pairs 
and threes, and the larger calyces and petals. (PL I, d.)

tibus, foliis magis ellipticis, minus coriaceis, saepissime perpaucis

differt. 
Frutex unimetralis vel altior, parceramosus, ramis ascendentibus,
