18 ANNALS OF THE ROYAL BOTANIC. GARDEN, CALCUTTA. 
long, straw-coloured, striate, ciliate on one edge, truncate at top in а narrow eiliate 
callus and bearing short auricles furnished with few long purple bristles ; ligule long, 
dark-coloured, ciliate. Zm/forescenee usually on separate leafless culms, but sometimes with 
flowers and leaves intermixed, branches many, fascicled, drooping, paniculately racemose ; 
rachis very slender, much jointed, bearing at the joints papery, straw-coloured, narrow 
(9 to 3 іш) sheaths 15 to 3 in. long, truncate or ending in a small leafy, 
subulate, imperfect blade, which enclose 2 to 3  pedicellate (or one sessile) spikelets. 
Spikelets loose, compressed, 1 to 22 in. long, bearing 2 empty glumes and 4 to 
8 fertile (or the last imperfect) flowers; rachille long-clavate, white—hairy at tip; 
empty glumes 2, linear-lanceolate; one rather blunt, short, the other long, mucronate, 
membranous, striate, glabrous; flowering glumes ovate, long-acuminate, mucronate, "6 to 
1 in. long, scabrous, striate; palea much shorter than flowering glume, 2-keeled, ciliate 
on the keels, sometimes bifid, l- to 2-nerved outside, l-nerved between the keels. 
Lodicules 8, ovate-faleate or ovate-acute, 3—5-nerved, fimbriate. Stamens long exserted, 
anthers blunt. Ovary glabrous, ovoid, elongate, surmounted by а short style which at 
once divides into 3 long, plumose, recurved stigmas. | Caryopsis linear-oblong, glabrous,

Mountains of the North-West Himalaya from the Sutlej to Nepal, above 7,000 
feet, first collected in flower by Wallich in 1821, and since then by Brandis in 1879 (2), 
by W. R. Fisher in Jaunsar in 1882, and by myself at Deoban, 9,000 ft., in 1892, 
and on Kedarkanta in Tehri-Garhwal, 9,000 ft., in 1893. | 
This is the common high level ringal of the North-West Himalaya, common in 
the undergrowth of the deodar and fir forests in moist localities, It usually flowers 
gregariously as it did in 1882 (see А. Е. Broun in Ind. Forester, vol. xii. p. 414, 
fig. 1) the seedlings from which flowering are now (1893) growing up. But isolated 
old. lowering clumps. may ђе occasionally .met with, such as those Г found in 1892 
and 1893. It is at once distinguished from A. fulcata by its prominent transverse 
veinlets; from A. jaunsarensis by its short rhizomes and cespitose growth; and from 
А. aristata, (to which I refer all the Eastern Himalayan specimens hitherto assigned 
to this, and which is very nearly allied to it,) by the narrower bracts with fewer 
spikelets, the absence of a hairy callus to the leaf-sheath, and other minor points. 
The culms are used for pipe-stems, basket-work, pea-sticks and other purposes.
