CL VII. GRAMINE2E (Stapf). 
[. Panicum - 
rooting from the lower nodes, simple or sparingly branched, terete, 
whitish, sparsely and very finely hairy, internodes mostly long- 
exserted and the intermediate 1-1J in. long. Leaf-sheaths thin, 
tight or at length involute and slipping off the stem, finely and 
loosely hairy, finely striate ; ligules very short, membranous, truncate, 
ciliolate ; blades linear-lanceolate from a shortly attenuated and 
constricted base, finely acuminate, 1-2J in. by 1J-4 lin. (the lower 
small), flat, very thin, flaccid, green, sparingly hairy on both sides 
with long extremely fine hairs, margins scaberulous, midrib very fine, 
whitish below, primary lateral nerves 1 on each side, very slightly 
differentiated from the other nerves. Panicles exserted, at least the 
terminal, flaccid and contracted, 1J-2J in. long, divided to the third 
degree ; common rhachis filiform, terete, striate, like its principal 
divisions smooth or slightly rough upwards and beset with scattered 
long and very fine hairs, lower and intermediate internodes 3-4 lin. 
long, upper decreasing very gradually ; lower primary branches 
flexuous, up to 1J in. long, finely filiform to almost capillary, loosely 
branched from the base, the branchlets divided in the same way, 
the latter distant by 2-3 lin. and up to 6 lin. long or the lowest much 
longer, divisions of all grades fascicled at the lower nodes ; pedicels 
capillary, 1-3 lin. long, tips very obscurely widened. Spikelets 
ovate-lanceolate, finely caudate, including the tail f-J- lin. long, pale 
greyish-green, very finely pubescent froni the glumes and lower valve. 
Glumes very dissimilar ; lower a minute roundish hyaline scale, 
one-fifth the length of the lower valve to which it is applied tightly ; 
upper corresponding in length and outline to the spikelet, produced 
into a fine curved bristle-like tail J-f lin. long, 5-nerved with the 
outer nerves very faint or almost suppressed. Lower floret barren : 
valve as long as the body of the upper glume, and very like it, 
3-nerved, oblong, acuminate ; valvule more or less reduced, oblong, 
acute, acuminate, keels very faint, scaberulous upwards. Upper 
floret oblong, obtuse, about f lin. long, whitish, polished.

This may be identical with P. delicatulum, Fig. & De Not. (in Mem. Ac. 
Torin. ser. 2, xii. 351, t. 20, fig. 1-13 ; Durand & Schinz, Consp. v. 746), 
collected by Figari on the Blue Nile ; but I have not seen specimens of Figari’s 
plant and on comparison of the description and figures of P. delicatulum with 
Cameron’s, I find the former to differ in the following points : more copious 
and subdichotomous branching, larger leaf-blades (3^ in. by 6 lin. ) with a glabrous 
upper face, larger spikelets with a comparatively shorter tail (body 1| lin., 
tail \ lin.) and larger false fruits (1 lin.). The dimensions of the spikelet given 
here are based on the authors’ figs. 1 and 2, which are said to be magnified 10 
times. The magnification of figs. 3-12 is given as 20, which, however, does not 
answer to the values deducible from figs. 1 and 2.

Perennial (?), up to over 2 ft. high. Culms erect, slender, terete, 
glabrous, internodes shortly exserted. Leaf-sheaths (upper only 
seen) tight, terete, smooth, glabrous except near the mouth and
