CL VII. GRAMINEiE (Stapf). 
[ Brcichiaria . 
slender, terete and adaxillarily channelled or more or less flattened 
upwards, terminating with a spikelet, scabrid along the angles, 
otherwise pubescent or glabrous. Racemes straight or slightly 
curved, the lowest J to over 1 in. long, gradually decreasing upwards, 
simple or very rarely slightly compound at the base with very short 
and scanty secondary racemes ; rhachis more or less triquetrous, 
J-f lin. wide, scabrid along the angles, pubescent or hirtellous, or 
glabrous ; pedicels mostly solitary or the lower paired, all very short 
and relatively stout, so that the spikelets are subsessile, or the longer 
of the lowest pairs up to lin. long, of the same vestiture as the 
rhachis, but usually with some longer stiff hairs. Spikelets secund, 
more or less 1-seriate or lower down irregularly 2-seriate, evenly 
distant by |~1 lin. and then laterally contiguous, rarely much more 
remote and spreading, except towards the base where the raceme 
may become interrupted, oblong to obovate-oblong, acute or apicu- 
late, slightly flattened on the back, 1-1 J lin. long, pale. Glumes very 
unequal ; the lower ovate, subacute, sometimes mucronulate, 
clasping, very thin, slightly less than half the length of the spikelet, 
3- to sub-5-nerved, the inner nerves anastomosing ; upper glume 
corresponding in outline and size to the spikelet, membranous, 
somewhat prominently 5-nerved, usually pubescent, often with the 
hairs more numerous, longer and white below the tip so as to form 
a small tuft, or sometimes quite glabrous. Lower floret neuter : 
valve very like the upper glume, if not slightly longer, less hairy, 
more faintly nerved and slightly depressed between the inner nerves ; 
valvule oblong, acute, delicate, more or less reduced or almost 
suppressed. Upper floret slightly shorter than the lower, or 
equalling it and then their tips frequently exposed when quite mature, 
broad-oblong, subacute, pale ; valve and valvule crustaceous, 
delicately granular. Anthers \ lin. long . — Panicum distichophyllum.
