part, J-J lin. wide, scabrid along tbe angles, otherwise pubescent 
or hirtellous and with some scattered long fine hairs, or more rarely 
glabrous ; pedicels short to very short, the longer of a pair rarely 
over J lin. long, finely filiform, angular, scabrid, otherwise of the same 
vestiture as the rhachis, but usually with some fine stiff white hairs, 
often almost as long as the spikelet. Spikelets mostly in secund 
short racemules or clusters of 6-2, these distant by more than their 
own length, except near the base where the secondary racemes are 
sometimes elongated ; spikelets oblong, subacute, slightly turgid 
and much gaping during flowering and frequently more or less so 
afterwards, 1 lin. long, pale or tinged with purple. Glumes very 
unequal, the lower ovate, acute or acutely acuminate, one-third to 
one-half the length of the spikelet, 2-5-nerved, very thin, often purple ; 
upper oblong, usually slightly shorter than the spikelet, membranous, 
more or less loosely pubescent, 5-nerved. Lower floret $ ; valve 
very similar to the upper glume but as long as the spikelet, with the 
inner side-nerves more apart and the space between them flat and 
glabrous or nearly so ; valvule oblong, tru icate or subacute, slightly 
shorter than the valve or more or less reduced ; anthers if present 
b lin. long. Upper floret as long as the spikelets, the tip and the 
sides frequently uncovered owing to the gaping of the spikelet 
and the shortness of the upper glume, elliptic, subacute, whitish ; 
valve and valvule thinly erustaceous, very finely granular. Anthers 
| lin. long. Grain broad-elliptic, f lin. by § lin., flattened on both 
sides, pea-green ; scutMlum equalling three-quarters of the length 
of the grain . — Panicum kolschyanum, Hochst. ex Steud. Syn. PI.

Vanderyst’s specimens are partly deformed (phyllody, nos. 3651 and 4375 ; 
Ustilago heterospora, no. 4354). A viviparous specimen collected by Maitland 
(no. Ill) in Uganda is evidently also this species.
