234 CLXXIII. GEAMINE^:. (J. D. Hooker.) [Oryzopsi8. 



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 convolute, 

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

 ovoid subrostrately acuminate, gl. I longer than II, awn of III y^-l in. 

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

WESTERN HIMALAYA ; from Kashmir to Kunawur and WESTERN TIBET, alt. 

 12-14,000 ft. DISTRIB. Affghanist. ? 



Stems densely tufted, forming a stout branching base, very slender, smooth. 

 Leaves 2-4 in., smooth or nearly so, acuminate, strict or flexnous ; ligule 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 -1 in. long. 0. effusa, Hack, ex 

 Herl. Duthie. Hazara and Baltistan, alt. 9-10,000 ft., Duthie. Karakorain, alt. 

 10,000 ft., Clarice. 



2. O. IVXunroi, Stapf \ tall, stem stout or slender, leaves narrow flat, 

 panicle effuse lower branches long many-fid, towards the ends, spikelets 

 : -i in. ovoid rostrately acuminate, gls. I and II equal, awn of III \- in.

 Piptatherum soongaricum, Duthie in Atkins. Gaz. N.W. Ind. 626 (naftie).

WESTERN HIMALAYA ; from Kashmir to Garwhal, alt. 7-11,000 ft. WESTERN 

 TIBET ; Ladak, Nubra and Zanskar, alt. 10-13,000 ft. DISTRIB. Affghan. 



Stem 2-4 ft., about as thick as a crow-quill. Leaves 4-10 by -j^-i 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 

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

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



3. O. aequigrlumis, Duthie Grass. N.W. Ind. 27; tall, rather stout, 

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

 many- fid. towards the ends, spikelets - in. ovoid acuminate, gl. I and 

 II equal, awn y-^ in. ?0. ccerulescens, Duthie Grass. N.W. Ind. 28 

 (name). O. Duthiei, Hack, ex Herb. Duthie. Piptatherum aequiglume, 

 Munro ex Duthie in Atkins. Gaz. N. W. Ind. 626 (name). Pipt. n.sp. Herb. 

 Strach. $ Wint. n. 2. 



TEMPERATE 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 IE 

 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. coerules- 

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