floret : valve somewhat shorter than the glumes, lanceolate, acute, 
2-nerved, ciliate upwards ; valvule similar but narrower and gla- 
brous. IJpper floret : valve almost as long as that of the lower 
floret, hyaline, very acute, 3-nerved, minutely ciliate; valvule 
slightly shorter, faintly 2-nerved. Anthers almost 2 lin. long. 
Stigmas over J lin. long. Grain narrowly oblong, 2 lin. long, terete 
at the middle, scutellum not quite reaching to the middle, hilum 
obovate, basal. Pedicelled spikelet : lower glume lanceolate, pro- 
duced into a ciliolate awn, which is twisted below and passes into a 
horizontally spreading bristle, about 1 in. or more long, frequently 
all the awns of the racemes pointing one way, flat, 3-nerved, pubes- 
cent or glabrous ; upper glume broadly lanceolate with an eccentric 
acute keel, with the broader side concave, otherwise as in the sessile 
spikelet ; florets as in the sessile if not smaller, the upper $ .

3. U. agropyroides, Hack, in DC. Monogr. Phan. vi. 272. Peren- 
nial. Culms up to over 2J ft. high, rather robust, straight, terete, 
simple, smooth, or slightly rough below the raceme, few-noded. 
Leaf -sheaths glabrous or sparingly hairy upwards, the low'er strongly 
striate, with their bases persistent ; ligules membranous, truncate, 
about 1 lin. long ; blades linear, tapering to a short setaceous point, 
about J ft. long and 2-3 lin. wide, flat, hirsute on both sides, rough 
along the margin, midrib slender. Raceme solitary, 6-8 in. long, 
dull purplish-brown, erect, glabrous except at the calli ; joints 
linear, compressed, slightly concave on the inner face, about 4 lin. 
long, more or less rough, ciliate along the inner angle, disarticu- 
lating very obliquely, scar with a membranous toothed ciliate appen- 
dage, exceeding the joint by up to 1 lin. ; pedicels similar to the 
joints but flatter and with a smaller membranous appendage, con- 
tiguous with them. Sessile spikelet with an obconical bearded 
callus, up to 1| lin. long, separated from it by a deep transverse 
groove, oblong-lanceolate, 4 lin. long. Glumes equal, lower acute, 
cartilaginous, slightly convex, glabrous, almost smooth with the 
exception of the keels which are rigidly ciliolate upwards, keel- 
nerves 2, intracarinal nerves about 4, slightly prominent ; upper 
glume of about the same length, thinly chartaceous, boat-shaped, 
obliquely linear -lanceolate in profile, acute, 3-nerved, the keels 
ciliolate above. Lower floret : valve slightly shorter than the 
glume, subhyaline, lanceolate, subacute, 2-nerved, obscurely ciliate 
near the tip, otherwise glabrous, with a similar valvule. Upper 
floret : valve hyaline, oblong-lanceolate, acute, finely 3-nerved, 
glabrous, with a shorter faintly 2-nerved valvule. Lodicules 
glabrous. Anthers 2J lin. long. Stigmas 1J lin. long. Pedicelled 
spikelets consisting of two reduced glumes and a small hyaline valve,
