Stem 2-3 ft., simple or branched, pubescent below the spikes ; nodes pubescent. 

 leaves 8-12 by f-li in., setaceously acuminate, more or less hairy, margins scabrid ; 

 sheath glabrous or margins ciliate j ligule stifif, oblong, truncate. Spikes 8-2J, 

 ^li in., simple or divided, rachis glabrous, axils bearded; joints and pedicels 

 flattened, subtrigonous, about as long as the spikelets, shortly ciliate. Spikelets 

 ^-i in., oblong-lanceolate, pale greenish ; callus minute, shortly bearded ; gl. I 

 chartaceous, 6-8-nerved to the tip, margins rather broadly inflexed from base to tip; 

 keels scabridly ciliate; II chartaceous, keel scabrid, 3-nerved; III = I, oblong, 

 obtuse, hyaline, ciliate, S-nerred, paleate, male, palea oblong-lanceolate 2-nerved 

 ciliate; IV = J III, glabrous, 3-nerved, lobes acute, awn i-J in. ; palea = the gl., 

 lanceolate, 2-nerved, glabrous. Pedicelled spikelet like the sessile, but gl. I hardly 

 channelled ; III epaleate ; IV male.— As Hackel remarks, this has the habit of a 

 PoUinia sect. Leptatherum (where I should have been disposed to plaoe it) with the 

 spikelets more of an Ischcemwm. I have seen no Concan specimen. 



27. X> robustum, Hoo&.f. ; tall, stout, leaves long narrow coriaceons 

 softly tomentose on both surfaces, spikes few racemed strict erect, joints 

 very stout obliquely truncate lower minutely puberulous, sessile spikelets 

 ^i in. ovate- or oblong-lanceolate acute coriaceous awnless dorsally flat 

 quite glabrous with 6-9 broad low nerves, keels scabrid above the middle, 

 II coriaceous 7-9-nerved, III 3-nerved paleate male, IV oblong apiculate 

 awnless.

Stem several feet high from a hard rootstock, hard, solid, nearly as thick as a 

 goose-quill, naked below. Leaves 12-18 by j-i in., narrowed from the base to the 

 long acuminate tip, sides incurved scaberulous, midrib very stout ; sheath long, finely 

 pubescent; ligule a brush of long hairs. Spi&es 4-5 in., lower stipitate; peduncle 

 stout, glabrous ; joints J shorter than the spikelets, dorsally rounded, ventrally deeply 

 concave. Sessile spikelets quite glabrous, appressed to the rachis, upper in the 

 spike smaller than the lower ; callus very short, stout ; gl. I sometimes channelled 

 in the middle, very variable in the number and position of the rib-like nerves, tip 

 minutely toothed, margins narrowly incurved ; II as long as I, eciliate ; III shorter, 

 male; palea, ovate-lanceolate, 2-nerved, eciliate; IT as long as III, rigidly mem- 

 branous, 3-nerved ; palea nearly as long, 2-nerved, both eciliate. Pedicelled spikelet 

 i smaller than the sessile ; gl. I oblong-lanceolate, acuminate, other gls. and palea as 

 in the sessile, but both flg. — Very unlike any other N. Indian species.
