Annual or perennial grasses. Spikelets usually 2-fld.,in solitary digi- 

 tate or fascicled articulate fragile spikes, binate, a sessile and pedicelled. 

 Sessile spikelets, Glumes 4, 1 oblong or lanceolate, flat, with inflexed margins, 

 truncate or 2-cuspidate, awnless ; II as long as I but narrower, concave, 

 acute obtuse or awned ; III hyaline, rarely chartaceous, paleate, trian- 

 drous, palea narrow ciiiate ; IY hyaline, bisexual or fern., usually cleft, 

 awned (rarely awnless), awn inserted in the cleft, or by a minute point 

 "below it, branching into 3-nerves; palea linear-lanceolate. Pedicelled 

 spikelet, like the sessile, or broader, often imperfect. Lodicules cuneate- 

 quadrate. Anthers linear. Styles long, stigmas long or short. Species 

 about 40, chiefly tropical. 



techcemum differs from Pollinia in the much larger gl. IV. of the sessile spikelet 

 which is usually cleft into lanceolate lobes, and, except in /. angusUfolium, in the 

 ' longer palea of that gl. I find that Hackel's sectional character founded on the shape 

 of the joints is unworkable. 



Sect. I. EUISCILEMUM. Spikes 2-3, rarely more. Gl. I of sessile 

 spikelets dorsally flat, not deeply channelled or depressed along the mesial 

 line. (See also I. robustum.) 



* Margins of gl. I narrowly inflexed or incurved from base to apex. 



t Leaves rounded at the base, sessile on the sheath. 



Pedicel of upper spikelet not 5 the length of the lower spikelets. 



1. aristatum, Linn. Sp. PI. 1049 (in part) ; perennial, leaves 

 sessile long narrow, spikes 2-3 2-5 in., gl. I of sessile spikelet nearly flat 

 oblong obtuse or notched with 2-4 marginal nodules or low transverse 

 ridges, IY deeply 2-fid, awn geniculately inserted at the cleft, upper spike- 

 let dimidiate-ovate. Kunth Enum. PI. i. 512, Suppl. 421 ; Hack. Monogr.

Throughout the Plains and lower Hills of INDIA, from Sikkim and Bengal to 

 Burma, and southwd. through the Deccan Peninsula to CEYLON. DISTRLB. China, 

 Malaya. 



Stem 1-4 ft., stout or slender, erect or decumbent at the base, simple or 

 branched above. Leaves 4-10 in. by i~H i n - finely acuminate, glabrous or silkily 

 hairy, base rounded or narrowed rarely subpetiolate ; sheath naked or hirsute; ligule 

 short or 0. Spikes stout or rather slender, internodes much shorter than the spike-
