Flowering glumes glabrous, the fertile one 3-awned ; central awn 
as long as the spikelet, protruding, bent in the middle and twisted 
in the lower half ; lateral awns very short, bristle-like. 
Simla. — Throughout India, ascending to 8000 ft. — China, Philippines. 
2. Arundinella brasiliensis, Raddi ; FI. Br. Ind. vii. 73. 
Glabrous or nearly so ; stems 1-5 ft. Leaves 6-12 in. Spikelets

rough, erect. Lower empty glume minutely bristly along the keel, 
with 3 prominent nerves. Flowering glume with a basal tuft of 
silky hairs, terminating in a single awn as long as the spikelet 
bent at the middle and twisted in the lower half. 
Simla. — Hilly districts throughout India. — China, Australia, S. Africa, 
S. Europe, tropical America. 
3. Arundinella Wailichii, Nees ; FI. Br. Ind. vii. 75. Usually

ju in. excluding the awn, usually in crowded clusters. Panicle 
narrow, contracted, 6-12 in. ; branches rough, J-l in., stiffly erect. 
Empty glumes bristly. Flowering glume tipped with a very short, 
straight, barely protruding awn. 
Simla, on dry banks. — E. Himalaya, 1000-6000 ft., Bengal plains. — China. 
I have seen no specimen, but it is recorded from Simla in the FI. Br. Ind. 
6. SETARIA. From the Latin seta , a bristle, referring to the 
bristly involucre surrounding the flowers. — Most temperate and 
tropical regions. 
Annual ; stems erect. Leaves flat, lanceolate, long-pointed. 
Ligule a fringe of hairs. Spikelets numerous, glabrous, usually 1- 
flowered, ovoid, about ~ in., jointed on very short stalks bearing 
an involucre of long, minutely barbed bristles, in spike-like or 
close, cylindric, tapering panicles. Empty glumes usually 3, mem- 
branous ; lowest small ; second and third nearly equal ; uppermost 
sometimes containing a male or rudimentary flower. Flowering 
glume 1 , of a firmer texture and smaller than the uppermost empty 
glume, deeply concave, containing a 2-sexual flower. Stamens 3. 
Styles 2, long, free to the base. Grain free, enclosed within the 
hardened glume and pale. 
Spikelets in a narrow, spike -like panicle. 
Fruiting glume wrinkled ....... 2 . S. glaucci: 
Fruiting glume smooth . . . . . - 5. S. viridis.
