Hotter pn-ts of INDIA, from Assam and Burma to Central India and south- 

 ward to CEYLON. DISTRIB. Austral., N. Zeald. 



Stem 8-18 in. from a creeping branching base ; nodes glabrous or sparsely 

 bearded. Leaves 1-3 in., rarely more, subscaberulous above or on both surfaces, 

 margins ciliolate, nerves or 23 very slender pairs, midrib obscure; sheaths 

 smooth, mouth and often margins ciliate. Panicle 1-3 in., contracted and ovoid 

 or pyramidal and open ; branches glabrous or obscurely scaberulous, and as the 

 pedicels very variable in length. Spikelets green or purplish, obtuse, smooth 

 and polished or scabrid or setulose; gl. I and II faintly many-nerved ; III and. IV 

 usually very unequal, III lonyer, flutter, thinner, shining ; IV coriaceous, glabrous 

 or pubescent, orbicular or broadly ellipsoid. I. mauritiana, Kunth, is a very 

 closely allied species, but lias gl. Ill and IV equal and similar; it is Panicum 

 dub him and bijionim, Lamk.

 pedicels spreading capillary, spikelets rather smaller. Ceylon; Peradeuiya, Trimen.

Low marshy ground, from the SIKKIM TERAI, BENGAL and SILHET to BURMA 

 and~south\vard to MALACCA, the NICOBAR ISLDS., and CEYLON. DISTRIB. China, 

 the Malay and Pacific Islds., S. America. 



Very variable in size ; stem rarely 6-8 in. high, nodes of stem glabrous or 

 ciiiate ; sheaths glabrous or sparsely hairy. Leaves flaccid or rather stiff, usually 

 spreading, nerveless or nearly so, glabrous or sparsely hairy on both surfaces. 

 Spikelnts as in I. auslralis, but usually smaller, glabrous, rarely sparsely setose ; 

 gl. I and II 5- or more- nerved ; IV glabrous or pubescent. The small states of this 

 plant look very different from typical I. awtraUs, but larger appear to unite them 

 b_y many intermediates. Trimen refers /. Meneritana, to /. au*irali.s, Mr. ttendle, 

 who has carefully compared the types of each in the British Museum, agrees 

 with me that it goes best with miliacea. He also informs me that Barman's Thes.
