 on both surfaces, base cordate, often unequally, with some- 

 times a short petiole, margins scabrid, midrib slender, veins 

 3-5 pairs, sheaths loose, glabrous or hairy, auricles large, ciliate, 

 united by the hyaline ligule; spikes 1 or 2, 2-3 in. long, 

 rhachis slender, fragile, internodes about \ in., dorsally silkily 

 ciliate ; sessile spikelet \ in., oblong, callus short, thick, 

 shortly densely bearded ; glume I coriaceous, ovate or oblong, 

 glabrous, smooth, polished, usually constricted about the 

 middle, margins narrowly incurved, lower half tumid, sides 

 sometimes nodose, upper thinner, flatter, bicuspidate, 2- 

 winged, and with green anastomosing veins between the 

 wings, which vary in breadth and are ciliolate, II chartaceous, 

 ovate-lanceolate, acuminate, 3-veined, tip bicuspidate with 

 often an interposed slender recurved awn sometimes longer 

 than the glume, keel smooth, III oblong-lanceolate, hyaline, 

 1-3-veined, 3-androus, upper margins ciliolate, palea oblong, 

 opaque, wings hyaline, IV shorter, deeply 2-lobed, lobes 

 obtuse, bisexual, palea narrow, 2-veined, awn |-| in., genicu- 

 lately inserted at the sinus; styles short, stigmas narrow; 

 > pedicelled spikelet, glume \ in. long, glabrous, callus obsolete, 

 pedicel \-\ as long as the internode, glume I flattened, with 

 the broad unilateral wing dimidiate-ovate, obtuse, margins

I find considerable variation in the ciliate or eciliate ligule and size 

 of the auricles of the l.-sheaths, in the form and sculpture of glume I 

 of the sessile spikelets, and in the form and ciliation of glume III and 

 its palea.
