Caralluma Nebrownii is one of the largest-flowered species 
in the genus, and is most nearly related to C. lateritia, 
N. E. Br., a native of the northern Kalahari desert, from 
which the plant now figured differs in having much longer 
_ pedicels, a more rugose corolla of a blackish-crimson colour 
~ flecked with very small yellowish spots on the disk and at the 
base of the lobes instead of a uniform brick red ; the corona 
in the present plant is also larger than that of C. lateritia. 
C. Nebrownii is allied also to C. huillensis, Hiern, an 
Angolan species, and to C. lutea, N. E. Br., a species from 
South Africa. In both of these plants the pedicels are 
shorter than in the subject of our plate; C. huillensis has 
moreover pubescent stems, while in C. lutea the flowers are 
yellow and the stems have a different facies,
