to be the most distinct, for undulatifoUus, though constant over wide areas, is only a 

 form of compositus with the branches of the panicle represented by one or a few 

 sessile or subsessile spikelets.

Tempeeate Himaiata, alt. 6-9000 ft., from Kashmir to Sikkim. Khasia 

 Hills, alt. 4-5000 ft., NiLfiHiBi Hills. — Distkib. Central and S. Europe, warm 

 regions generally. 



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

 ^1 in., from ovate to narrow lanceolate, finely acuminate, glabrous or sparsely 

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

 spreading hairs ; lower clusters of spikelets rarely produced into a very short spike. 

 Spikelets J-i in. (excl. awns), solitary with a second reduced to an awn, or clustered, 

 glabrous or nearly so. O-l. I 3-nerVed, ciliate; awn f in. or less; II usually 

 awned, 5-nerved ; III acute or shortly awned, 7-nerved, palea narrow or 0. — Though 

 as observed under the genus, this grass is only a form of compositus, 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 hy 

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

 Wallichian Herbarium. 



2. O. compositus, Beauv. Agrost. 54; stem usually tall from a 

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

 spikelets usually loosely imbricate, awns rather stout pale or dark. Kunth
