Stem very slender, flaccid, prostrate, straggling, 6-1 8 in. long, 

 creeping below, with slender, often filiform, ascending, glabrous 

 branches, 3-6 in. high ; 1. J-f in., ovate or ovate-lanceolate, 

 acute or obtuse, membranous, striate and pilose on both 

 surfaces with long hairs, base rounded, sheath slender, \-^ in., 

 glabrous or ciliate, ligule a ridge of long hairs; panicle i-ij in. 

 long and broad, laxly branched, rhachis and branches filiform, 

 quite smooth ; spikelets y^tv m - diam., few and distant, on 

 long capillary pedicels, globose; glumes I and II orbicular- 

 oblong, almost hemispheric, dorsally hispid with long spreading 

 hairs, obscurely 7-veined, III rather longer, oblong, mem- 

 branous, male, IV smaller, hemispheric, coriaceous, villously 

 tomentose, female, palea glabrous. 



Low ground in swampy places. Southern Province, Riseland, Udugama 

 (Ferguson). Spikelets pale green.

The above description is from specimens in the Peradeniya Her- 

 barium ; others from India vary greatly, having stouter stems with hairy 

 nodes, glabrous much larger 1., and approach I. australis so closely as 

 to suggest I. miliacea being a form of that species. Dr. Trimen indeed 

 referred /. meneritana (which is certainly /. miliacea) to australis, but 

 Mr. Rendle, who has examined the type specimen of that plant in the 

 British Museum, agrees with me that it is referable to miliacea. The 

 Meneritana of the Sinhalese is, as Dr. Trimen has pointed out (Journ. 

 Bot. 1. c), not an /sac/me, but Panicum miliare. I. minutula, Kunth, 

 is a very small form from Udugama (Ferguson).
