almost glabrous. Leaf -sheaths somewhat loose, pale, striate, 
densely ciliate upwards, more or less (sometimes very sparingly) 
shortly hirsute with the hairs tubercle-based, nodes pubescent to 
subvillous ; ligules reduced to a densely ciliate rim ; blades lanceolate 
to linear-lanceolate from a wider and semi-amplexicaul base. 
1J-6 in. by 4-6 lin., rarely much longer (to 10 in.) and then linear and 
narrowed towards the base, soft, flat, pale or yellowish-green, loosely 
and often finely hirsute with tubercle-based hairs, rarely almost 
glabrous, margins usually crisped or wavy and more or less ciliate, 
midrib slender, primary lateral nerves about 5 on each side, usually 
obscure on the upper side. Inflorescence of mostly 4-7 (rarely 
fewer or more) erect or at length more or less spreading stiff or 
slightly flexuous sessile or subsessile spiciform secund racemes ; 
common axis J-2 (rarely 3) in. long, subsemiterete below, much 
flattened upwards, pubescent. Racemes moderately dense, 2- 
seriate, simple, 1-2 in. long, solitary or here and there approximate 
and then unevenly distributed ; rhachis straight or slightly wavy, 
triquetrous, flat on the back, about \ lin. wide, villous at the base, 
glabrous upwards, rarely sparingly hairy, angles scabrid ; internodes 
lin. long ; pedicels solitary, reduced to short stout stumps with 
discoid tips, frequently bearing some long spreading hairs. Spikelets 
laterally contiguous or subcontiguous, ovate- to elliptic-oblong, very 
acute, 2-2J lin. long, greenish, glabrous or pubescent. Glumes 
dissimilar ; lower broad-ovate, subobtuse to acute, clasping at the 
base, f-1 lin. long, glabrous or sparingly and minutely pubescent, 
about 5-nerved, nerves slightly raised and anastomosing ; upper 
glume corresponding in size and outline to the spikelet, prominently 
7-11- (mostly 9-) nerved, glabrous or pubescent. Lower floret £ or 
barren : valve very similar to the upper glume, but flat or slightly 
depressed, 5-7-nerved with the inner side-nerves distant, glabrous or 
pubescent, very rarely with a lateral appressed fringe ; valvule 
oblong, acute, slightly shorter than the valve ; anthers 1 lin. long. 
Upper floret rotundate-elliptic, greenish to pale brown, 1J-1 J lin. 
long ; valve finely transversely rugose or granular, mucro up to J lin. 
long, sparingly barbellate. Grain rotundate-elliptic in outline, much 
compressed, about 1 lin. long, yellowish or greenish ; scutellum 
three-quarters the length of the grain —U. pubescens, Kunth, Rev.
