12. X. Impressum, Sack. 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 snbsemilunar pits in the lower % above 

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

India, Ruegel. The Cokcan ? Herb. Dalnell. 



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

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

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

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

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

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

 3-nerved, ciliate ; IV much shorter, glabrous ; awn 1-1 J in., 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-nervedj 

 IV mucronate. — I have seen only a fragmentary specimen in Dalzell's Herbariumi 

 The sculpturing of gl. I probably varies,

 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.

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

 pedicels stout, trigonous, about i-J shorter than the spikelet, angles and excised 

 hollow tips long-cillate. Sessile spikeleta i 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 Ion?, 

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

 scaberulous, awn about ^ in. ; palea as long as the gl., lanceolate, 2-nerTed, 

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