CL VII. GRAMINEiE (Stapf). 
[Sacciolepis. 
oblong in profile, curved x with a slender recurved acumen, mem- 
branous, finely 7-nerved, with a longer or shorter fringe of tubercle- 
based hairs along the margin and along each side of the keel. Lower 
floret barren : valve similar to the upper glume and of about the 
same length, but less curved on the back, 7-nerved on each side, with 
a large triangular hyaline window-like area at the base and an 
oblique fringe of tubercle-based hairs (up to f lin. long) ascending 
from the middle of the keel, the tips of the valves hyaline above the 
fringe ; valvule narrowly linear, somewhat shorter than the valve, 
finely 2-keeled, with very narrow flaps from the middle downwards. 
Upper floret oblong, acute, 1 lin. by J lin., white, polished. 
Grain oblong-elliptic in outline, § lin. by | lin. ; scutellum elliptic- 
oblong, exceeding the middle of the grain ; hilum suprabasal, puncti- 
form. — Panicum ciliocinctum , Pilger in Engl. Jahrb. xxxiii. 48.

2. S. cingularis, Stapf Annual (?), probably up to 2 ft. high. 
Culms geniculately ascending from a decumbent rooting base with 
the roots partly aerial, terete, up to 2 lin. diam., smooth and glabrous, 
branched with the branches in scanty tiers, all flowering, internodes 
3-4 in. long, the lower laid bare by the slipping off of the sheaths ; 
branches of a tier unequal, the outermost up to 1 ft. long, the inner 
gradually shorter, all branches of 2 internodes, the upper about 
double the length of the lower. Leaf-sheaths coarsely striate, 
shortly hirsute, the lower wide and almost papery, about 3 in. long, 
upper tight and more herbaceous ; ligules membranous, whitish, 
truncate, up to 1 lin. long ; blades linear, mostly imperceptibly 
passing into the sheaths, long-tapering to a callous point, of lower 
leaves flat and up to 6 by 2J- lin., or those of the branches very short 
and subulate-convolute, rather plump, very loosely and finely hairy, 
densely papillose above on all the nerves, otherwise quite smooth, 
midrib and primary lateral nerves (2 on each side) slender, more or 
less differentiated from the very fine prominent secondary nerves. 
False spikes at length long-exserted on slender flexuous peduncles, 
cylindrical, 1-| in. by 3-4 lin., very compact ; pedicels very short, 
somewhat stout, very sparingly puberulous, closely appressed to and 
rising direct singly or in pairs from the common axis, tips discoid. 
Spikelets lanceolate, acuminate, symmetrical or more or less oblique, 
2 lin. by f lin., pale greyish-green, bearded. Lower glume lanceolate, 
acute to subacute, over three-quarters the length of the spikelet, 
with a firm narrow finely 3-nerved back, on each side with a row of 
fine rigid hairs inside the wide hyaline margin ; upper ovate 
(when flattened out), acuminate, membranous, 9-nerved, shortly 
and loosely hairy all over, often with some long hairs on the sides. 
Lower floret $ : valve very similar to the upper glume, if not more 
abruptly acuminate and of equal length, 9-nerved, glabrous or almost
