lin. long, glabrous, somewhat darker than the sessile ; glumes sub-

intracarinal nerves ; upper 3-nerved, eciliolate ; valve lanceolate- 
oblong, subacute, 2 lin. long, 2-nerved, ciliolate ; anthers as in the

Var. lysocladus , Stapf. Panicle over 2 ft. long, loose owing to the lengthening 
of all the axes ; racemes pale green, pleasantly contrasting with the reddish 
spathes. — A ndropogon connatus, Eyles in Trans. Roy. Soc. S. Afr. v. 295, partly;

10. C. citratus, Stapf in Kew Bulletin , 1906, 357. A tall per- 
ennial, throwing up dense fascicles of leaves from a short oblique 
annulate sparingly branched rhizome, usually barren but occasion- 
ally giving rise to a stout erect culm up to over 6 ft. high, 7-8- 
noded and simple below the panicle, up to 4 lin. thick at the base, 
glabrous, smooth, longest lower internodes up to over 1 ft. long, 
pruinose below the nodes. Leaf-sheaths terete, those of the barren 
shoots much widened at the base, and tightly clasping each other, 
narrow and separating upwards, with rounded shoulders at the mouth, 
4 in. to 1 ft. long, subcoriaceous, quite glabrous and smooth, more or 
less cinnamon coloured or russet on the inside ; sheaths of the culms 
tight, shorter than the internodes, finely pubescent or velvety at 
the nodes ; ligules very short, scarious, rounded or truncate ; blades 
linear, long-attenuated towards the base and tapering upwards to a 
long setaceous point, up to over 3 ft. long by 3-9 lin. wide, very 
firm, glaucous-green, glabrous, smooth or more or less rough upwards 
and along the margins ; midrib somewhat stout below, whitish on 
the upper side ; primary lateral nerves 4-6 on each side, raised 
particularly above with 2-4 secondary nerves between them. 
Spatheate panicle decompound to supradecompound, loose, 1 to over 
2 ft. long, nodding ; internodes 4 to over 6, the longest up to 8 or 9 
in. long, rapidly decreasing in length upwards ; lowest primary 
branches undivided at the base, up to over 1J ft. long, and up to 
5- or 6-noded, the following forming mixed tiers of very unequal 
variously compound and simple rays, ultimate tiers up to 4-rayed ; 
rays 1- J in. long, filiform and glabrous ; lower subtending leaves 
with tight sheaths and normal but abbreviated blades ; spathes 
narrow-lanceolate, acute or acuminate, 2-1 in. long, herbaceous or 
subherbaceous, with narrow membranous margins. Spatheoles 
very narrow, linear-lanceolate to almost subulate when inrolled, 
7-9 lin. long, acute or finely acuminate, reddish to rich russet ;
