the scabrid cartilaginous and often undulate or crisped margins, 
and some rigid long cilia towards the base, midrib and lateral nerves 
(5-6 on each side) very slender, the latter rather inconspicuous. 
Inflorescences terminal, long-exserted on a slender peduncle, of 4-7 
obliquely erect or spreading somewhat slender sessile or subsessile 
spiciform secund racemes ; common axis slender, 1J-3 in. long, 
semiterete below, flattened upwards, glabrous or here and there 
with a few very fine hairs, scaberulous along the angles. Racemes 
moderately dense to almost loose, 2- or indistinctly pluriseriate, 
simple, solitary, the lower and intermediate to over 2 in. long and 
about equidistant, the uppermost much shorter and more approxi- 
mate ; rhachis almost straight, rather flat, J to over J lin. wide, 
subtriquetrous with the facial angles low, hairy at the base, glabrous 
or sparingly setose upwards, angles scabrid, internodes \ to over £ lin. 
long ; pedicels reduced to subterete stumps or the longer of a pair 
distinctly elongated and up to over J lin. long, usually with some fine 
white bristles below the discoid tips. Spikelets of each rank dis- 
contiguous, ovate-lanceolate, acutely acuminate, 2 lin. long, pale 
greyish-pubescent or quite glabrous. Glumes very dissimilar, 
membranous ; lower broad-ovate, clasping at the base, acute, 
£ lin. long, 3- or sub-5-nerved, tips of nerves more or less anastomos- 
ing ; upper glume corresponding in size and outline to the spikelet, 
prominently though finely 7-9-nerved. Lower floret barren : valve 
very similar to the upper glume, somewhat flat on the back, 5-nerved ; 
valvule broad-oblong, acuminate, somewhat shorter than the valve. 
Upper floret broad- to rotundate-elliptic in outline, about 1 lin. 
long, pale, very delicately wrinkled or granulate ; valve with a 
scaberulous mucro f lin. long . — Panicum setigerum, Retz. Obs. iv. 15 ;

Also in India and Ceylon. Retzius described his Panicum setigerum from a 
specimen stated to have been collected in China by Bladh ; but there is no other 
record of its occurrence in that country. 
The African specimens have glabrous spikelets. In India, however, the 
pubescent form appearstoj^ prevalent. 
10. U. insculpta^Sta^L Annual, up to 4 and even 5 ft. high, but 
mostly much shorter. Culms solitary or in scanty tufts, erect or 
more usually geniculately ascending, often rooting from the lowest 
nodes, simple or more or less branched, 4-7- (rarely more-) noded, 
terete or angular and sometimes compressed below, glabrous. Leaf- 
sheaths somewhat loose, the lowest often slipping off the culm, 
subherbaceous, striate, finely ciliate along the margins, nearly always 
greyish-pubescent or subvillous at the nodes, otherwise glabrous or 
more or less softly hirsute (particularly upwards), with tubercle-based
