Boeckeler, which is a bifid-styled variety of C. pustulatus, Vahl, and it is by no means 
rare among Carices. 
С. obtusiflorus, Vahl, is widely scattered over Tropical and South Africa and Madagascar, 
the variety flavissimus having nearly the same distribution.

Var. MINOR, spiculis minus compressis, Huilla, in pascuis dumetosis incendio vexatis, 
prope Nene, no. 6906. 
This form differs from the typical plant in being very stunted, with less-compressed 
spikelets rather crowded together, and dull reddish in colour. It has probably been 
affected by the grass-burning. The same form occurs in South Africa. 
The plant is a native of the west coast of Africa and Madagascar.

This species is closely related to C. margaritaceus, Vahl, but differs in the narrow strict 
rush-like leaves, more than a foot in length, the dilated base of the involucral leaves, 
the narrower more acute glumes, and the general habit. Тһе glumes are, like those of 
C. margaritaceus, of a beautiful silvery colour.
