 blades linear, tapering to an acute point, 3 to 7 inches, by 2-3 lines, rigidly erect, 

 flat or convolute, with scattered stiff hairs, particularly near the base, rough on 

 both sides, glaucous. 



PANICLE contracted, obovate to linear-oblong, 2 to 6 inches long, glaucous,

 flexuous, bearing spikelets from the base or almost so, lowest up to 2 inches long.

 internodes, upper closer, shortly but distinctly pedicelled, about 2i lines long. 



GLUMES subequal, lanceolate, acute, 2 to 2j lines long, minutely scabrid ; 

 margins and tips hyaline ; valves up to 2| lines long, entire, acute or very minutely 

 2-toothed, very shortly awned from below the readily splitting pruinose tips,

Drawn from Buchanan's 282, the only specimen in the Herbarium. 



A note in the Flora Capensis says : " Rather different from the other species 

 of the genus, and perhaps not a true Diplachne." 



Also in Transvaal and Basutoland.
