Hotter p*rt8 of India, from Assam and Burma to Central India and south- 

 ward to Ceylon. — Distkib. 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 2-3 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, II I longer, flatter, thinner, shining ; IV coriaceous, glabrous 

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

 closely allied species, but has gl. Ill and IV equal and similar ; it is JPaniowm 

 duhium and bijlorum, Lamk. 



Var. effusa, Trim. Ca'. Ceyl. PI. 104; panicle pyramidal, branches longer, and 

 pedicels spreading capillary, spikelets rather smaller. — Ceylon ; Peradeniya, Trimen. 



13. X. miliacea, Rcth Nov. PI. 58 ; stems very slender prostrate 

 ■widely creeping and branched below then ascending, leaves small ovate- 

 lanceolate acute margins not or faintly thickened, panicle small coatracted 

 or spreading lax-fid. spikelets 2'5-1-V ^^-t pedicels short tips hardly thickened.

Low marshy ground, from the Sikkim Tebai, Bkngal and Silhjct toPFBMA 

 and southward to Malacca, the Nicobae Islds., and Cbtlon. — Disteib. China, 

 the Malay and Pacific Islds., S. America. 



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

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

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

 Spikelets as in I. amstralii, but usually smaller, glabrous, rarely sparsely setose j 

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

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

 by many intermediates. Trimen refers I. Meneritana to I. australis, Mr. Rendle, 

 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 Burman's Thes.
