Annual or perennial grasses. Spikelets usually 2-fld.,in solitarjr 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, a'wnless; II as long as I but narrower, concave, 

 acute obtuse or awned; III hyaline, rarely chartaceous, paleate, tnan» 

 drous, palea narrow ciliate; IV hyaline, bisexual or fern., nsaally cleft, 

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

 below it, branching into 3-nerves; palea linear-lanceolate, PedicelhO' 

 spihelet, like the sessile, or broader, often imperfect. Lodicules cnneate- 

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

 abont 40. chiefly tropical. 



Isch(Bmum differs from Pnllinia in the much larger gl. IV. of the sessile spikt^l®* 

 which is nsaally cleft into lanceolate lobes, and, except in 7. angustiJoUum, in tbe 

 longer palea of that gl- I find that Hackel's sectional character founded on the shap« 

 of the joints is unworkable. 



Sect. I. EuiscH^MTJM. Spihea 2-3, rarely more. Gl. I of sessile 

 spikeleta dor&ally flat, not deeply channelled or depressed along the mesial 

 line. (See also J. rohttstum.)
