CL VII. GRAMINEiE (Stapf). 
[ Brachiaria . 
terminating with a short barren point, overtopped by the uppermost 
raceme ; racemes lj-f in. long, rather stiff, sessile or subsessile, 
simple ; rhachis almost straight, triquetrous, up to J lin. wide, 
scaberulous along the angles ; pedicels mostly solitary or the lower 
paired, usually all (except the terminal) very short and relatively 
stout, so that the spikelets become subsessile, pubescent with some 
longer hairs near the tips. Spikelets strictly secund, more or less 
1 -seriate or 2-seriate at the base, very close and laterally contiguous 
or the uppermost more distant, obovate-oblong in outline, apiculate, 
slightly turgid, 1 \ to almost 1| lin. long, pale. Glumes very unequal ; 
the lower broad-ovate, subacute, clasping at the base, about one-third 
the length of the spikelet, very thin, 5-7-nerved, the faint side- 
nerves more or less distinctly anastomosing ; upper corresponding 
in shape and size to the spikelet, membranous, finely pubescent, 
5-nerved, with few transverse veins below the tip. Lower floret 
neuter : valve very similar to the upper glume, if not less pubescent 
between the inner side-nerves ; valvule delicate, oblong, § lin. long. 
Upper floret oblong to elliptic-oblong, subapiculate, 1 lin. long, 
pale ; valve and valvule thinly crustaceous, smooth or almost so.

39. B. glauca, Staff. Perennial (always ?), 1 to almost 2 ft. high, 
very glaucous in all its parts, densely tufted on a short rhizome, 
innovations intra vaginal (always ?), cataphylls thin, submembranous, 
whitish-pubescent. Culms slender, geniculately ascending, terete 
or the lower internodes compressed, particularly when they are 
elongated and arching, simple or sparingly branched, up to 7-noded, 
glabrous or more or less pubescent or the lowest internodes almost 
villous. Leaves delicately pubescent to almost villous or the 
uppermost sometimes glabrescent ; sheaths thin, the lower loose 
and sometimes slipping off the culm, or like the upper rather tight ; 
ligules a dense fringe of hairs, about J lin. long ; blades linear 
from an equally wide or attenuated base, long-tapering to a fine 
somewhat callous point, 3-6 in. by 1|— 3 lin., flat, flaccid, margins 
scaberulous, not or very finely cartilaginous, primary lateral nerves 
3-d on each side, slightly raised below, midrib slender, whitish, 
shallowly channelled above, somewhat raised below. Panicle at 
length exserted, 3-5 in. long, subsecund, of 3-9 mostly solitary 
(rarely the lowest 2-nate) distant oblique spike-like racemes ; common 
axis very slender, angular, channelled adaxillarilv, scabrid along the 
angles, more or less pubescent or glabrous. Racemes slender, the 
lower 1-1 J in. long, the upper gradually shorter, straight or slightly 
flexuous, sessile or subsessile with a marked villosulous pulvinus at 
the base, or the lowest on a peduncle up to 4 lin. long, simple, rarely 
with 1 or 2 short 3-spiCulate secondary racemes at the base, loose ;
