Diffusely branched and rooting below, stems often almost filiform. Leaves 

 always small, sheaths glabrous or hairy. Ponicie 1-4 in., inclined or nodding; 

 spikes rarely 1 in., very pale, racbis glabrous or pubescent. Spikelets -rtj-J in. 

 (excl. awns) ; gl. I ciliate, 1-3-nerved, awn J in. or less j II 3-5-nerved, awned j III 

 6-9-nerved, shortly awned, palea 0. — Usually very distinct from 0. compositus, but 

 I have found specimens growing in the Jheels, with spikes nearly two inches long 

 and stouter awns, forming a transition to that plant. Wall. Cat. 8678 is a very 

 small Silbet form, with ovate leaves i— J in. Clarke found it also in Silhet. — 0. 

 africanus is the earliest name for the species under Oplismenus, but Burmannii is of 

 universal adoption, and is the earliest specific name ; both were given by Beauvois, 

 0. africanus in 1807, 0. Surmannii in 1812.
