238 CLXXiii. GRAMiNE^. (J. D. Hooker.) {Alopeeurus. 



* Perennials. Panicle ovoid, or oblong. 



1. A. blmalalcuS; HooJc. f. ; npper leaf-sheaths inflated, panicle 

 oblong or subcapitate, spikelets -1-:^ in., gls. I and II lanceolate sub- 

 aristatelj acnminate hirsute with spreading hairs longer than the spikelet 

 is broad, III much shorter than I and II, awn twice as long as the spikelet 

 or more. 



Kashmib and Dbas, alt. 10-14,500 ft., Falconer, &c. 



Stem 6-18 in., subsolitary, erect from a creeping base, rather stoat. Leaves 

 3-5 in., erect or spreading, upper shorter lanceolate acuminate ; upper sheaths 3-5 in., 

 ower appressed ; ligale large, scarions, toothed. Panicle l-lj in., grey-greea or 

 purplish. Spikelets membranous, hairs flaccid ; gls. I and I [ connate belotr, tips 

 dark ; III i shorter than I or II, obtuse, apicnlate. — Most nearly allied to A. phala- 

 roides, Schur, of Hungary, which is hardly distinguishable from A. hrachyatachyus. 

 Bieb., of Siberia ; but the spikelets of A. himalaicus are much larger than iu those 

 species, from which its acuminate gls. I and II and short III at once dis- 

 tinguish it.

 soft. Spikelets suhsilky ; gl. I and II lanceolate, acuminate, more or less connate

 being more than a form of A. pratensis, L.
