somewhat rigid, glabrous or with a few hairs towards the base, 
rough along the margins and the slender almost keeled midrib 
below, spinulously ciliate towards the tips, lateral primary nerves 
4-5 on each side, slender and more or less prominent. Racemes on 
shortly or long exserted peduncles, 2J to over 3 in. long, flexuous, 
more or less silvery-hairy ; joints linear, 1J lin. long, villous, with 
the hairs 1 lin. long ; pedicels similar but shorter and more slender. 
Sessile spikelet lanceolate, including the downwards bearded callus 
3J-4 lin. long. Glumes unequal ; lower acuminate with a slender 
more or less 2-fid acumen, rigidly ciliolate from the middle upwards, 
otherwise glabrous and smooth, intracarinal nerves very faint, 5-7, 
balsam-ducts distinct ; upper lanceolate, acute, 2 J lin. long, glabrous, 
1-3-nerved. Lower floret almost 2J lin. long : valve linear-lanceo- 
late, acute, glabrous, obscurely 2-nerved. Upper floret not quite 2 
lin. long : valve obscurely 3-nerved ; valvule 0. Anthers 1-1 J lin. long. 
Pedicelled spikelet linear-lanceolate, 2-2 \ lin. long, acute. Glumes 
entire, subequal ; lower rigidly ciliolate and keeled on one side, with 
a balsam-duct close to the keel, ecarinate and glabrous on the other, 
glabrous on the back, about 5-nerved apart from the keel. Florets 
similar to those in the sessile spikelet, but the upper — Hack, in

rently a fairly tall grass, smooth, glabrous, much-branched upwards 
with the branches flowering (only the upper parts known). Leaf- 
sheaths smooth, glabrous, striate ; ligules reduced to a very short and 
densely hairy rim ; blades long-tapering from the base, where they 
are 1-1J lin. wflde, narrow, convolute, glabrous, smooth, nerves 
prominent below. Racemes numerous, 2 to over 3 in. long, on 
slender peduncles which are 2-5 in. long and enclosed up to or 
beyond the middle in a narrow sheath, more or less hairy, straw- 
coloured. Rhachis fragile ; joints up to 1J lin. long, densely ciliate 
along the outer angle, minutely puberulous on the back, disarticu- 
lating very obliquely ; pedicels similar, about the same length but 
more slender. Sessile spikelet oblong-lanceolate, including the 
small bearded callus 3J-4 lin. long. Glumes unequal ; lower charta- 
ceous-herbaceous, long-acuminate, with the acumen 2-fid to the 
base into 2 subulse, pectinate-ciliate from the base upwards, glabrous 
and smooth or more or less hairy on the back, obscurely 5-nerved, 
balsam-ducts distinct ; upper lanceolate, acute, up to 2 lin. long, 
with a few minute hairs, ciliate upwards, faintly 3-nerved. Lower 
floret about 2 lin. long ; valve lanceolate, ciliolate, faintly 2-nerved ;
