C. glandulosa belongs to the group ofC. pyracanthoides Engl. s. lat., as pointed out byJ. P. M. Brenan, Kew Bull.1953, 104. This author regardsC. lugardae N. E. Br.,C. seineri Engl. andC. berberidifolia Engl. as synonyms ofC. glandulosa. The species seems to be distributed over a wide area of Southern Africa, from Mozambique through the Rhodesias to Bechuanaland, Transvaal, and South-West Africa. — It is noteworthy that we found the resins ofC. roxburghii (Stocks) Engl. (=C. mukul) and ofC. viminea Burtt-Davy, a species still somewhat related toC. pyracanthoides (Brenan), to be completely devoid of triterpene acids both free and combined as glycosides.
