Plains of India ; from the Punjab to Bengal, Burma, Central India, and 

 southward to Malacca and CsrLON. — Distbib. All hot countries. 



Stems 1-5 ft., ascending from a creeping base. Leaves 3-10 by J-J in., glabrous or 

 hairy, lisule very short. Spikes forming a narrow secund coitipouud panicle 2-6 in. 

 long ; rachis trigonous and branches pubescent villous or nearly glabrous. Spik^lets 

 sliortly pedicelled ; gl. I and II usually silky, sometimes villous. III much shortest, 

 punctulate, very shortly awaed. 



3. XSACHNEi Br. 



Perennial grasses. Spikelets small or minute, loosely panicled, not or 

 obscurely articulate with the pedicel, subglobose or obovoid, l-2-3il. 

 Glumes 4, often all separately deciduous from a minute rashilla ; I and II 

 subeqaal, convex, herbaceous, empty ; III and IV palette, equal and both 

 cinvex, or III larger flatter thinner; III male, rarely 2-aexaal; IV articu- 

 late and often stipitate on the raohilla, hemispheric, coriaceous, fern, or 

 bisexual. Lodicules very minute. Stamens 3, rarely 4-6. Grain, free 

 within the hardened gl. and pale. — Species about 2.5, tropical and sub- 

 tropical. 



The 2-fld. spikelets not articulatn on the pedicel, with us'ially snbequal convex 

 empty gls., and gl. IV being articulate on the racliilla, distinguisli Isocline from 

 Pawcum. I find great varieties in the persistence of the empty glume on tlio 

 pedicel. Mr. Eendle informs me that he has seen tracer of a fifth glume and palea 

 in I. australis, which favours the claim of the genus to be referred to Foacea ; and 

 he has shown me a most minute prolongation of the racliilla at the base of the 

 palea of gl. IT in the same species. Many of the species so run into their allies, 

 that I regard the following limitation of most as open to question. The smooth 

 hispid or bristly empty gls. afibrds no specific character, nor does the glabrous or 

 pubescent fl. gl. 



* Spikelets ^'^-tV in long. 



+ Glumes I and II longer than IT, cuspidate or acuminate.
