[Brack iaria. 
lateral more or less distinctly differentiated below, midrib channelled 
above, somewhat prominent underneath. Inflorescences secund, 
of 2-8 very rarely solitary distant sessile straight or more often 
arching or falcate spike-like racemes ; common axis 7-1 in. long, 
triquetrous or semiterete, glabrous, with scabrid or ciliolate rarely 
setnlose angles. Racemes secund, dense, 2 to over 6 in^long, some- 
times with one or more arrested spikelets at the apex, simple, usually 
1-seriate with the spikelets superposed, occasionally partly 2-seriate ; 
rhachis straight or wavy upwards, rather flat or convex on the back, 
concave on the face, up to over | lin. wide, scabrid and loosely ciliate 
along the angles, cilia rising from small tubercles along the margins, 
villosulous at the base, internodes 1-1-2 lin. long ; pedicels solitary, 
very short, stout, usually sparingly setulose. Spikelets closely 
contiguous, oblong to elliptic-oblong, rather obtuse or subacute, 
turgid, 2-3 lin. long, glabrous rarely sparingly hairy upwards, pallid, 
frequently with purple tops or variously tinged with purple. Glumes 
very unequal, membranous to subchartaceous ; the lower broad- 
ovate, obtuse, clasping, half the length of the spikelet or almost so, 
7-11 -nerved, often purple, glabrous, the upper glume corresponding 
in outline and size to the spikelet or slightly shorter, very convex, 
sometimes minutely apiculate, 7-9-nerved, with a few cross-veins 
near the tip, usually glabrous. Lower floret as long as the spikelet, 
similar to the lower glume, but flattened or depressed on the back, 
5-nerved , valvule oblong, subobtuse, finely keeled, flaps rather broad ; 
anthers 1J lin. long. Upper floret equalling the upper glume or 
as long as the spikelet, oblong' in outline, sometimes with a short 
blunt incurved point, pale or slightly greenish ; valve and valvule 
crustaceous, very delicately pitted, flaps of valvule very broad above 
the base. — Panicum brizanthum, Hochst. in Flora, 1841, Intell. i. 19
