The species are very variable, and great as is dissimilarity between the average 

 states of the following, apparent intermediates between them occur. 



1. O. lateralis, Stapf; very slender, leaves short filiform convolnte, 

 panicle very narrow strict, branches short erect few-fld., spikelets \-^ in. 

 ovoid snbrostrately acuminate, gl. I longer than II, awn of III To~i i". 

 very caducous. Piptatherum laterale, Munro ex Regel in Act. Mart,

Westeen Himalaya ; from Kashmir to Konawur and Western Tibet, alt. 

 12-14,000 ft.— DiSTBiB. Affghanist. ? 



SterA^s densely tufted, forming a stout branching base, very slender, smooth. 

 Leaves 2-4 in., smooth or nearly so, acuminate, strict or flexnons ; lignle oblong, 

 hyaline. Panicle 4-10 in., thin, racliis smooth, branches and pedicels scaberulous. 

 Spikelets ovoid or ovate-lanceolate, green or tipped with red-purple ; gls. I and II 

 subrostrately acuminate, faintly 5-nerved, pair next the midrib arching and anasto- 

 mosing with the median, outer pair similarly arching the last lower down ; II more 

 obscurely 3— 5-nerved ; III about i shorter than II, lanceolate, finely subsilkily 

 pubescent, tip minutely 2-toothed; awn usually very short, very slender, not twisted. 

 Lodicules 2, ovate, hyaline. Anther-cells minutely bearded. Grain oblong. 



Var. effusa, lower branches of panicle larger J-1 in. long. O. effusa. Rack, ex 

 Serb. Duthie. — Hazara and Baltistan, alt. 9-10,000 ft., DutHe, Karakoram, alt. 

 10,000 ft., Clarice. 



2. O. Munrol; Stapf; tall, stem stout or slender, leaves narrow flat, 

 panicle efEuse lower branches long many-fld. towards the ends, gpikelets 

 >— i in. ovoid rostrately acuminate, gls. I and II equal, awn of III i-|^ in.

Westeen Himalaya ; fi-om Kashmir to Garwhal, alt. 7-11,000 ft. Wbstebn 

 Tibet ; Ladak, Nubra and Zanskar, alt. 10-13,000 ft.— Disteib. Affghan. 



Stem 2-4 ft., about as thick as a crow-quill. Leaves 4r-10 by ^^-} in., finely 

 acuminate, hardly scaberulous; margins nearly smooth ; ligule oblong, hyaline. 

 Panicle 6-12 in., branches in' distant pairs, filiform, nearly smooth ; lower 

 naked for 1-3 in., then branching shortly and bearing shortly pedicelled spikelets. 

 Spikelets variable, from ovate to lanceolate ; gls. I and II green or tipped with 

 purple or wholly purple ; III and its palea pubescent. Lodicules, stamens and grain 

 aa in lateralis, but larger. — The larger broader glumes longer awn and great size 

 of the plant distingnish this from var. effusa of lateralis. 



3. O. sequig'luinis, Duthie Grass. N.W. Ind. 27; tall, rather stout, 

 leaves long flat, panicle long effuse or contracted, lower branches long 

 many-fld. towards the ends, spikelets 5— |- in. ovoid acuminate, gl. I and 

 II equal, awn ^-i in. PO. ccernlescens, Duthie Grass. N.W. Ind. 28

Tbupbeate Himalaya ; from Kashmir to Sikkim, alt. 6-10,000 ft. 



Very closely allied to 0. Munroi, but usually a stouter plant, and taller, 

 spikelets larger often of a dark or dull green mixed with purple, gls. I and it 

 not so beaked, leaves longer, awn and anthers longer. It may be a state of that 

 plant from moister or warmer localities. I have seen no specimen of 0. coemles- 

 cens, Duthie, which was collected at Gungotri, alt. 9-10,000 ft.
