9. I. javana, Nees ex Mfq. PL Ju,u/li. 376, & Fl. Ind. Bat. iii. 462; 

 stout, erect, leaves 2-3 in. acute or obtuse stiff glaucous beneath, margins 

 much thickened, panicle lax, branches and pedicels very long and slender 

 tips obconic, spikelets obovoid iV~rV i n - long. Panicum batavicum, Steud.

Habit of I. himalaica. Stem 2-3 ft., quite smooth, stiff; nodes ciliolate. Leaves 

 erect or erecto-patent, strict, nearly smooth on both surfaces, or sparsely hairy 

 beneath, with 911 pairs of often very obscure nerves, margin smooth or serrulate ; 

 sheaths quite smooth, margins glabrous or ciliate, mouth bearded. Panicle 

 2-4 in., glabrous, lower branches 2-3 in. ; pedicels more thickened at the tip than 

 in most other species. Spikelets broad, smooth ; gl. I and II often polished ; nerves 

 many, obscure ; III and IV usually equal and both hemispheric; III rarely larger 

 and flattened, usually male; IV fern, or bisexual; sometimes both Ilf. and^IV. are 

 triandrous or hexandrous, in one spikelet III was triandrous and IV tetrandrous. 

 A much larger plant than I. australis. 



10. I. Clarkei, Hook.f. \ stem short very slender, leaves 1-2 in. 

 ovate-lanceolate acute very thin, margins thickened serrulate, panicle 

 2-3 in. pyramidal, branches horizontal and pedicels capillary tips slightly 

 thickened, spikeletsj ^V" sV i n 



SIKKIM HIMALAYA; meadows in the Lachoong valley, alt. 8-11,000 ft. 

 J. D. H. MUNNIPORE ; on Kohima, alt. 5800 ft. Clarice. 



Stems 6-12 in., almost filiform, base prostrate. Leaves spreading, almost mem- 

 branous, nerves many faint, midrib obscure ; sheath and its mouth often strongly 

 ciliate. Panicle long-peduncled, branches 1 in. and less. Spikelets scattered, 

 hispid, green or purplish ; gl. IV. hispidly pubescent. Apparently a distinct little 

 species with very small spikelets, but possfbly a small state of I. aliens. 



11. I. rigrida, Nees ex Steud. Syn. Gram. 95; stems rigid much 

 branched from the base, leaves ^-1 in. 'rigid spreading and recurved ovate 

 to ovate-lanceolate almost pungent scaVtrid base cordate margins thickened, 

 panicle small pyramidal glandular, spikelets few ^V in., pedicels lon.g slender 

 tip ,subclavate. Miff. Fl.Ind. Bat. iii. 461. I. Myosotis. BenTk. Fl. HoncjTc.

TENASSEEIM, Heifer. NICOBAR ISLDS., Kurz. DISTRIB. Java, Borneo, China. 



Stems 616 in., generally very long decumbent and naked below, internodes 1-1^ 

 in., naked. Leaves deeply striate, with finely acuminate acicular tips, margins 

 smooth ciliolate or serrulate ; sheaths in., smooth scabrid or bristly. Panicle I in., 

 peduncle stout; branches horizontal. Spikeletx few, hispid; gl. I and II many- 

 nerved, III and IV glabrous. I take this to be the Javan I. rigida, Nees, from 

 Steudel's description, It further agrees well enough with the descriptions of 7. 

 firmula and I. monticola, Buese. 



Glume III usually flatter and thinner, and often longer than IV. 



12. I. australis, ,.Z?r. Prodr. 196; stems tufted ascending, leaves 

 short lanceolate or linear-lanceolato acute margins not or very slightly 

 thickened, 1 sheath smooth, panicle ovoid, or pyramidal, spikelets globose 

 iVi 1 - i"- glabrous or setose, tips of pedicels hardly thickened. Kunth
