which is stout and obtuse on the back and very slender on the 
face, over 1 lin. wide, slightly rough on the angles, internodes up 
to 1 lin. long ; pedicels solitary, slender, very short, glabrous. 
Spikelets dense, but those of one rank hardly contiguous, although 
incumbent on those of the other, oblong, subacute, somewhat flat 
on the back, 2J-2| lin. long, drying brown. Glumes very dis- 
similar, separated by an internode, J lin. long, thinly membranous ; 
lower very broadly ovate, shortly and acutely acuminate, broadly 
clasping, one-third to almost half as long as the spikelet, 11- 
nerved, the nerves anastomosing ; upper corresponding in outline 
and size to the spikelet, hispidulous towards the tip, 5-nerved, the 
nerves more or less raised. Lower floret as long as the spikelet : 
valve very similar to the upper glume ; valvule almost as long as 
the valve. Upper floret 2-2J lin. long, oblong, subapiculate, 
brownish ; valve and valvule crustaceous. Anthers 1| lin. long, 
purple. Stigmas purplish -black. — Panicum inter stipitatum, Stapf

15. B. platytsenia, Stapf Perennial and apparently tall (base 
not known). Culms somewhat stout, upper internodes terete, 
glabrous and smooth, 7-8 in. long. Leaf-sheaths (upper) terete, 
tight, strongly nerved, glabrous except for some fine tubercle- 
based hairs in the upper part ; ligules a dense fringe of rigid hairs, 
4 lin. long ; blades lanceolate-linear to linear from a broader 
rounded base, long-tapering to a slender point, 4-7 in. by J-l in., 
flat, thin, quite glabrous, midrib slender, prominent below, lateral 
primary nerves 5-7 on each side, fine. Inflorescence erect, over 
6 in. long, subsecund, of 10-12 spreading and usually arching 
sessile or (owing to the arrest of the spikelets) shorty peduncled 
(the lowest) spiciform secund racemes ; common axis ending 
abruptly or with a short point above the uppermost raceme, terete 
or subterete and slightly channelled below, subtriquetrous or 
flattened towards the top, finely pubescent on the concave or flat 
face, otherwise glabrous, smooth. Racemes dense, 2-seriate, 
simple, 24-1J in. long, with the uppermost spikelets arrested and 
minute, unequally distant (the lowest by up to 2 in., the following 
by 1-f in.), or here and there approximate or opposite or 2-nate ; 
rhachis ribbon-shaped, subherbaceous, up to 1J lin. wide, with 
a slender midrib slightly raised on the face, glabrous except at 
the villosulous base, margins minutely ciliolate, internodes about 
| lin. long ; pedicels solitary, extremely short, slightly flattened, 
alternately to the right and the left of the midrib. Spikelets 
laterally subcontiguous or those of one rank subimbricate, ovate- 
oblong to broad-oblong, acute, somewhat flat on the back, 2-2J 
lin. long, pale greenish, Glumes very dissimilar, membranous ;
