CL VII. GRAMINEiE (Btapf). 
[ Panicum . 
from a suddenly contracted and rounded base, tapering to a long 
fine point, 1J-6 in. by 3-7 lin., thin, flat, green, more or less softly 
and shortly hairy, sometimes almost velvety, rarely quite glabrous, 
midrib very slender, whitish ; primary lateral nerves 3-4 on each side, 
usually inconspicuous, margins scabrid to minutely spinulose, some- 
times crisped. Panicle soon expanding and then usually permanently 
open and extremely loose, broad-oblong to ovate in outline, 2-6 in. 
by 2-3 in., divided to the second or third or low down to the fourth 
degree, all the divisions sub capillary to capillary, flexuous or wavy, 
finely scaberulous, like the very slender primary axis more or less 
beset with long fine spreading white hairs, or at least the principal 
towards their bases and the pedicels below their tips, hairs of the 
axis usually tubercle-based, primary branches solitary or irregularly 
approximate, the lower mostly divided from 3-4 lin. (rarely up to 
1 in.) above the base ; pedicels very slightly thickened upwards, 
frequently paired, those of a pair very unequal, the shorter from 
\ (rarely) to 3 lin., the longer up to 8 lin. long. Spikelets oblong, 
obtuse, somewhat turgid, 1J to over 1J lin., pale green or flushed with 
purple, glabrous. Glumes very dissimilar, faintly nerved ; lower very 
small, rounded, very obtuse, one-seventh to one-fifth (rarely one-third) 
the length of the lower floret, hyaline, nerveless ; upper corresponding 
in size and shape to the spikelet, membranous, broadly rounded on the 
back, 5-nerved. Lower floret $ : valve very like the upper glume, 
5-6-nerved ; valvule almost as long, oblong, subacute, with broad 
flaps throughout ; anthers almost 1 lin. long. Upper floret <8, 
oblong, acute, almost as long as the lower, whitish, smooth, slightly 
glossy ; valve and valvule thinly crustaceous. — Durand & Schinz,

9. P. transvenulosum, Stapf. Evidently perennial. Culms 
geniculate, terete, smooth, glabrous, more than 6-noded, branched 
from the lower and intermediate nodes, branches obliquely erect 
or almost in continuation of the preceding internode, pushing the 
main culm aside. Leaf-sheaths tight, terete, glabrous except along 
the ciliolate or pubescent margins, shorter than the internodes, 
strongly striate ; ligule a ciliolate rim ; blades linear-lanceolate 
from a slightly rounded base, long and finely acuminate, 3-4 in. by 
4-7 lin., spreading, green, rather thickly herbaceous, sparingly and
