bearded ; gl. I coriaceous, keels glabrous narrowly winged above ; II ovate-lanceolate, 

 keel obtuse smooth; III lanceolate, 3-nerved, paleate; IV shorter, oblong, glabrous, 

 awn -f in., palea minute. Pedicelled spikelets smaller, awnless ; gl. I 5-7-nervcd, 

 winged on one side. 



12. I. impressum, Hack. Monogr. Androp. 210; slender, prostrate 

 below, leaves ovate- or oblong-lanceolate cordate lower narrower petioled, 

 spikes 2 villous, gl. I of sessile spikelets linear-oblong flat dorsally broadly 

 irregularly depressed with shallow subsemilunar pits in the lower above 

 it winged and 2-cuspidate, II dorsally rounded with a median gibbosity 

 and an auricle-like wing above it, IV cleft to above the middle, awn short 

 geniculately inserted at the cleft. 



INDIA, Huegel. The CONCAN ? Herb. Dalzell. 



Stem 4-8 in., quite glabrous, branching upwards. Leaves 2-3 in., upper in. 

 broad, sparsely hairy beneath, margins thickened, scaberulous, sometimes crenulate; 

 sheath compressed, glabrous ; ligule oblong. Spikes yellow ; joints and pedicels 

 stout, clavate, ciliate with rigid hairs, forked at the top. Sessile spikelets 53- in., 

 shining ; callus short, broad, bearded ; gl. I narrowed and margins subnodulose at 

 the base, wings erose ; II obtuse, chartaceous, ciliate ; III oblong-lanceolate, hyaline, 

 3-nerved, ciliate; IV much shorter, glabrous; awn 1-H '"> with very stout column 

 and golden tip ; palea oblong, obtuse, glabrous. Pedicelled spikelets smaller than 

 the sessile; gl. I obtuse, glabrous, many-nerved, winged on one margin ; II 7-nerved; 

 IV mucronate. I have seen only a fragmentary specimen in DalzelPs Herbarium. 

 The sculpturing of gl. I probably varies. 



13. I. Feildingrianum, Eendle in Journ. Bot. xxii. (1894) 101 ; stem

 glabrous below the middle hairy above with 6-8 nerves anastomosing at 

 their tips, keels scaberulous, II 6-nerved keeled aristulate, IV deeply 2-fid, 

 awn inserted between the broad obtuse lobes.

Upper leaves 4-5 by -f in., narrowed from the base to the acuminate tip, 

 rigid, pubescent beneath, 16-20- nerved ; sheath pubescent; ligule short, truncate. 

 Spikes 3-3| in., erect, fragile, peduncle villous towards the tip'; joints and 

 pedicels stout, trigonous, about j shorter than the spikelet, angles and excised 

 hollow tips long-ciliate. Sessile spikelets in., narrowed to the base; callus 

 cuneiform, densely bearded; gl. I obtuse or 2-toothed, keels very narrowly winged 

 towards the tip ; II rather longer than I, scabrid above and narrowed into the short 

 recurved awn; III ovate-oblong, obtuse, hyaline, faintly 3-nerved; palea as long, 

 lanceolate, subchartaceous, with broad rounded hyaline wings ; IV hyaline, sub- 

 scaberulous, awn about ^ in. : palea as long as the gl., lanceolate, 2-nerved. 

 Pedicelled spikelets smaller, keels of gl. I winged on one side ; IV not awned. 



** Margins of gl. I of sessile spikelet broadly incurved below the 

 middle. 



t Keel of gl. II winged above the middle (see also I. murinum). 



14. I. muticum. Linn. Sp. PL 1049; glabrous, creeping, branches
