Stem 6-10 in., rigid, leafy, geniculately branched below, 

 glabrous or pubescent ; 1. \-2\ in., ovate or ovate-lanceolate, 

 acuminate, base amplexicaul, flat, rigid, closely striate, midrib 

 obscure, glabrous pubescent or villously tomentose, margin 

 sometimes cartilaginous, sheath long or short, ligule obscure, 

 hairy; panicle on a short or long strict ped., ovate or oblong, 

 1-4 in. long, rhachis and branches rigid, strict, angular, 

 smooth scabrid or ciliate, at length spreading; spikelets sub- 

 secund, globose, tjt-tV m - diam., very shortly stoutly pedicelled, 

 erect ; glumes I and II subequal, cuspidate, strongly 7-9- 

 veined, longer than III and IV, more or less pubescent or 

 setulose, III and IV subequal, or III the largest, hemi- 

 spheric, coriaceous, more or less pubescent, III fern., IV

Stem 2-3 ft, sparingly branched, rather stout, glabrous or 

 sparingly ciliate, nodes pubescent; 1. distant, 2-4 in., ovate- 

 or oblong-lanceolate, acute or acuminate, thin, flat, many- 

 veined, and closely striate, scabrid above or on both surfaces, 

 margins ciliate, base rounded or amplexicaul, sheath i|-2^ in., 

 margins ciliate, ligule of hairs; panicle 3-4 in., spikelets as in

Endemic. 



Perhaps only a larger state of I. Kunthiana, as supposed by Thwaites, 

 but the specimens of elatior are very distinct-looking, are much larger, 

 with thinner 1. and a larger many -fid., usually more contracted panicle 

 with longer branches. The spikelets at length wholly disarticulate from 

 the very short pedicel.
