 sessile or subsessile spikelets.

Stem 1-2 ft., nsnally very slender, simple or branched below. Leaves 1^-6 by 

 J-1 in., from ovnte to narrow lanceolate, finely acuminate, glabrous or sparsely 

 hairy ; sheaths glabrous or hirsute. Spilce 2-5 in. ; rachis glabrous or pilose with 

 spreading hairs ; lower clusters of spikelets rarely produced into a very short spik*"* 

 Spikelets i~\ in. (excl. awns), solitary with a second reduced to an awn, or clustere<l» 

 glabrous or nearly so. Gl. I 3-nerved, eiliate; awn f in. or less; II usually

 as observed under the genus, this grass is only a form of compositusy it keeps its 

 characters of the inflorescence throughout its distribution, and may hence be regarded 

 as distinct. The Nilghiri form {acuminatus, Nees) has very narrow leaves, 3-4 *>/ 

 J-i in. It is remarkable that no specimen of this species should exist in tbtf 

 Wallichian Herbarium.

 decumbent base, leaves 2-7 in, lanceolate, spikes 4-10 1-6 in. long or more,
