Kunth refers Drége’s n. 75 doubtfully to R. vilis. I have pre- 
ferred to follow Nees’s indication, and to constitute it a new 
species under the name assigned to it by him in Dr. Sonder’s 
herbarium, but nowhere published. The male plant differs from 
R. vilis, Kunth, in its more robust habit, larger size of all its parts, 
in the more branched and spreading panicle, the curved spikelets, 
&c.; the female plant differs in the larger number and different 
form of the spikelets and in the more acutely pointed glumes.

In one of the specimens examined by me, the pyramidal tuft of 
leaf-bearing branchlets was borne on a long erect culm like the 
fertile one.
