11. S. Jeffrey sii^ Stapf. Perennial; rhizome creeping, wiry; 
stolons short, covered with tough glabrous prominently striate 
cataphylls. Culms loosely tufted, up to 1J ft. high, ascending, 
subcompressed below, about 8-noded, wiry, glabrous, simple or more 
often with short barren branches below and 2-5 distant flowering 
branches from above the middle. Leaf-sheaths slightly longer or 
shorter than the internodes, rather firm, faintly striate, glabrous, 
the lower compressed, keeled, the upper subterete, all dull pale green 
like the blades except the basal, which are yellow to brown ; ligules 
very short, truncate, ciliolate; blades folded or involute upwards 
when young, at length flat, linear, long attenuated to an acute 
point, very slightly constricted at the base, 3-6 in. long, or those of 
the barren shoots much shorter, 1J to almost 2 lin. wide, firm, more, 
or less hairy towards the junction with the sheath (hairs very fine, 
white, spreading, 1-1 A lin. long), or glabrous, smooth on both faces, 
rough on the margins, midrib very slender, prominent below, lateral 
nerves numerous, fine ; spathes very narrow, up to 2 in. long, with 
or without a rudimentary blade, dull purplish or reddish. Eacemes 
on slender peduncles which are slightly thicker towards the tips and 
terminate in an oblique cu pule, at length mostly long-exserted from 
the spathe, fragile, 2J-3 in. long, 8-12-jointed, silkv-villous ; joints 
3|- lin. long, narrowly linear-cuneate with an asymmetrical toothed 
appendage, greenish, tinged or mottled with purple, loosely hairy 
on the back, ciliate, uppermost cilia up to 2 lin . long ; pedicels 
similar, but more slender, with a very oblique appendage. Sessile 
spikelet linear-lanceolate, including the obtuse bearded callus 3J-4J 
lin. long, loosely hairy on the back. Glumes subequal ; lower 
chartaceous, 2-mucronulate, dull green or tinged with red, rather 
flat on the back, scaberulous on the keels, intracarinal nerves about 
6, obscure ; upper glume slightly shorter, membranous, acute, 3- 
nerved, keels scaberulous upwards, margins obscurely ciliolate. 
Lower floret reduced to an oblong valve up to 3J lin. long, 2-nerved, 
hyaline, tinged with carmine below. Upper floret 9 • valve over 
3 lin. long, 2-fid to one-quarter or one-third of its length ; lobes 
lanceolate, acute, ciliolate ; awn about 7-10 lin. long, column 
dark, slender, bristle white, usually much longer than the column. 
Valvule 0. Stamens 3, anthers 1J lin. long. Grain lanceolate
