[ Urochloa . 
flat or wavy, frequently somewhat rigid, green, quite glabrous or 
more frequently ciliate downwards, with long stiff hairs or sometimes 
also pubescent or softly hirsute, margins cartilaginous, scabrid, 
midrib very slender, lateral nerves numerous, close, very fine, the 
primary hardly differentiated. Inflorescence at length usually long- 
exserted, ovate to obovate-oblong in outline, from 1 to over 3 in. 
long, of few to over 12 obliquely erect or spreading slender secund 
spiciform racemes ; common axis slender, semiterete and adaxially 
channelled below, angular upwards, scaberulous along the angles. 
Racemes solitary, upwards gradually approximate or irregularly 
crowded into false whorls, 6-15 lin. long, sessile or subsessile, simple 
or subcomposite at the base with very short secondary racemes, 
2- or irregularly pluriseriate, dense to somewhat loose ; rhachis 
slender, slightly wavy, triquetrous, ~ lin. wide, pubescent or 
villosulous at the base, scabrid along the angles, internodes J-l lin. 
long ; pedicels paired (or the lower in clusters of 3), unequal, the 
longer up to J lin. long, slender, angular, the other very short to 
rudimentary, or solitary, usually with some long spreading white 
hairs and small discoid tips. Spikelets or their pairs or clusters sub- 
contiguous or discontiguous or crowded downwards, elliptic-oblong, 
acute, up to 1 lin. long, glabrous or greyish-pubescent, greenish, 
rarely tinged with purple. Glumes very dissimilar ; lower reduced 
to a small rounded or truncate and sometimes apiculate nerveless 
scale, 6~5 lin. long, upper corresponding in size and outline to the 
spikelet, distinctly 7-nerved, glabrous or densely pubescent. Lower 
floret barren, with or without rudimentary stamens ; valve very 
similar to the upper glume, 5-nerved ; valvule oblong, subacute, 
shorter than the valve. Upper floret elliptic, pale, finely trans- 
versely rugulose, over f lin. long ; valve with a minute mucro.
