238 OLXXIII. GRAMINEJ;. (J. D. Hooker.) [Alopecurus. 



* Perennials. Panicle ovoid or oblong. 



1. A. himalaicus, Hook. f. ; upper leaf-sheaths inflated, panicle 

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

 aristately acuminate 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. 



KASHMIR and DBAS, alb. 10-14,500 ft., Falconer, &c. 



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

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

 ower appressed ; ligule large, scarions, toothed. Panicle 1-1 in., grey-green or 

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

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

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

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

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

 tinguish it. 



2. A* arundinaceus, Poir. Enm/cL viii. 766 ; rootstock creeping, 

 panicle cylindric, spikelets 1 in., gl. I and II connate below acute keel 

 ciliate with long hairs, awn short. Boiss. Fl. Orient, v. 487 ; Steud. Syn.

WESTERN HIMALAYA, alt. 8-12,000 ft., from Kashmir to Garwhal. DISTRIB. 

 Westward to Europe, N. Asia. 



Stem 2-4 ft., erect, slender. Leaves 6-10 in., acuminate ; upper sheaths slightly 

 inflated, 4-6 in. long ; ligule rounded. Panicle 1-3 in. by %-\ in. diam., green, 

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

 at the base or to above it ; III acute, tip scaberulous ; awn subbasal. I doubt this 

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



** Annuals or subperennials. Panicle cylindric. 



3. A. aristulatus, Michx. Fl. J3or. Am. i. 43 ; stems slender genicu- 

 lately ascending, leaves glaucous, panicle slender, spikelets T V-ro ^ n - 

 oblong, gls. I and II hyaline obtuse softly ciliate, III truncate, awn 

 median-dorsal short, anthers oblong bright yellow. A. fulvus, Sm. Engl.

WESTERN HIMALAYA; Kashmir, in marshes, alt. 6-14,000 ft., Clarke, Duthie. 

 DISTRIB. Europe, N. Asia, N. America. 



Stem 6-18 in., creeping below, flaccid. Leaves 4-8 in., linear, flat; upper sheaths 

 somewhat inflated ; ligule elongate. Panicle 1-2 in. by | in. diam., green. Gls. 

 I and II free or connate at the very base, elliptic, obtuse. Regarded by various 

 authors as a variety of A. geniculatus, L.
