Brachiaria . ] clyii. Gramine^i (Stapf). 527 
terete to semiterete and more or less deeply channelled or tri- 
quetrous upwards, scabrid along the angles, glabrous. Racemes 
numerous, solitary or irregularly approximate, sometimes paired or 
in false whorls, shortly peduncled (the lowest) or subsessile, obliquely 
spreading, usually more or less flexuous, 2- or irregularly pluri- 
seriate, 3 (rarely 5) to 1 in. long, mostly compound and then fre- 
quently interrupted or the upper, rarely all, simple and more or 
less dense, glabrous, greenish or tinged with purple ; rhachis flat, 
herbaceous with a slender raised midrib up to J lin. wide, with pro- 
jecting scabrid angles, villosulous at the base, otherwise glabrous, 
internodes of the more evenly dense racemes J-l lin. long ; secondary 
racemes usually very short and 6-3-spiculate, or of the lowest racemes 
occasionally up to 1 in. long ; pedicels solitary or paired, all very 
short, or if paired then the longer up to | lin. long, scaberulous with 
smooth discoid tips, frequently with a few set riles. Spikelets late- 
rally contiguous or discontiguous, those of the secondary racemes 
frequently imbricate, oblong to lanceolate-oblong, acute, somewhat 
flat on the back, 14-lf lin. long, glabrous. Glumes dissimilar ; 
the lower broad-ovate, acute to subacute, from less than a third to 
not quite half the length of the spikelet, membranous, fai ntly 3- 5- 
nerved, often tinged with purple ; upper corresponding in outline 
and size to the spikelet, 5-7-nerved with few faint cross-nerves 
towards the tips. Lower floret g valve as long as the upper glume 
and similar to it, but 5-nerved and more or less depressed on the 
back ; valvule narrowly oblong, subacute, almost as long as the 
valve, with narrow flaps ; anthers 1 lin. long. Upper floret 
slightly shorter than the spikelet (mostly 1| lin. long), oblong, sub- 
acute or very minutely apiculate, pale yellowish ; valve and valvule 
crustaceous, very finely transversely wrinkled or almost smooth ; 
stigmas blackish-purple,- very conspicuous . — Panicum muticum,
