Racemes erect on peduncles as long as or almost as long as the spathe 
and terminating with an asymmetrical cupuliform appendage, 1-1 1 
in. long, 8-10- jointed, reddish with silvery hairs ; joints clavate, 
rather stout, slightly curved, concave on the inner face, about 2-2 j 
lin. long, including the oblique tubular denticulate appendage, 
which may be up to 1 J lin. long, scaberulous on the back, increasingly 
pubescent downwards, with the hairs at the base (callus) f lin. long ; 
pedicels linear in outline, concave on the face, with a short mem- 
branous rim at the top, hairs as in the joints. Sessile spikelet 
linear-lanceolate, slightly convex on the back, including the obconical 
obtuse densely villous callus 2-J-3 lin. long, whitish-green or tinged 
with red. Glumes equal ; lower chartaceous-membranous, acu- 
minate, 2-dentate, keels narrowly winged upwards, densely silky 
from the middle downwards, glabrous above, intracarinal nerves 3, 
obscure ; upper glume lanceolate, membranous, narrowly mucro- 
nate-acuminate, 1- to sub-3-nerved, glabrous apart from the ciliate 
margins and keel. Lower floret reduced to an ovate-oblong sub- 
obtuse hyaline ciliolate nerveless valve, slightly over 1 lin. long. 
Upper floret ovate, 2 -fid to beyond the middle, lobes linear-lanceo- 
late, acute, awn 5-6 lin. long, kneed below the middle, column dark 
brown, bristle white ; valvule minute, ovate, ciliolate, nerveless. 
Anthers J lin. long. Grain linear-lanceolate in outline, 1J lin. long, 
slightly compressed on the back, scutellum elliptic-oblong, not quite 
reaching to the middle. Pedicelled spikelet 1 \ lin. long, reduced to 
2 glumes ; the lower greenish, membranous, scaberulous, many-nerved, 
with a short bristle from between 2 minute teeth ; the upper hyaline, 
3-nerved. — Andropogon nodu losus , Hack, in Flora, 1885, 116, and in

Pilger (in Engl. Jahrb. xxxiv. 127) describes a var. glabrescens collected by 
Kersting, No. 260, in the savannahs of Kirikiri, Togoland, characterising it by the 
raceme being glabrous with the exception of white beards at the base of the joints. 
^ 8. S. griseum, Stapf. Annual (?). Culms erect, very slender, 
over 1 ft. high, sparingly and distantly branched, all branches 
flowering, usually solitary, internodes exserted, terete, glabrous, 
or finely pubescent below the nodes. Leaf -sheaths tight, more or 
less hirsute upwards, slightly pubescent or minutely bearded at the 
nodes ; ligules scarious, short, ciliolate ; blades linear, tapering to 
an acute point, to over 3 in. by 1J lin., .flat, slightly hirsute at the 
base, otherwise glabrous, rough along the margins, brownish-green, 
primary lateral nerves 2-3 on each side, hardly stronger than the 
secondary ; spathes very narrow and tight, 1J-2 in. long, bladeless, 
glabrous. Racemes erect, on filiform straight peduncles which
