254 DR. M. T. MASTERS ON THE SOUTH AFRICAN SPECIES 
This species varies considerably in stature, number of spikelets, 
&e. ; moreover the aspect of the immature spikelets is often consi- 
derably different from that pertaining to their fully developed 
condition. The bluntish, white-edged scales are useful guides in 
the discrimination of this species. The variety d is subject to 
the same diversities of size, &c.,as the species. Kunth has given 
the name R. oligostachyus to a form with elongated flexuose culms 
and large solitary spikelets. Steudel (in herb. Fielding.) gave the 
name A. monostachyus to a starved form of the species with 
slender, slightly flexuose culms and small spikelets. Some of the 
forms much resemble R. Garnottianus, but in that species the 
spikelets are more numerous, and the bracts are more acutely 
pointed, while their membranous edge is not so well marked, and 
their mucros are less abrupt than those of R. bifidus.

In Dr. Sonder’s herbarium some specimens of this plant are 
labelled as R. dichotomus by Nees. It is closely allied to R. bifidus, 
and may, indeed, be merely a form of that variable species.
