The DECCAN PENINSULA, from Canara southwd. BURMA, the MALAYAN 

 PENINSULA and LACCADINE ISLDS. CEYLON, common. DISTRIB. China, Malaya, 

 Australia. 



Rootstock very stout, creeping for several feet in sand ; branches 2-10 in. , 

 stout, usually leafy up to the spike ; nodes glabrous. Leaves 1-6 in., rarely more, 

 sessile or subsessile, flat, stiff, base rounded or cordate, brown when dry ; sheath 

 smooth ; ligule obscure. Spikes 1-1| in., joints and pedicels stout, 3-gonous, = 

 about half the sessile spikelet, truncate, shortly ciliate. Sessile spikelets | in., 

 glabrous, callus very large, smooth ; gl. I acute, thickly coriaceous, shining, 

 obscurely many-nerved, dorsally ciliate above the middle, margins below broadly 

 incurved ; II larger, rigid, glabrous, 5-nerved ; III oblong, obtuse, glabrous, palea 

 with a narrow hyaline wing; IV = II, chartaceous, convolute, 5-nerved; palea 

 oblong-lanceolate, keels ciliate. Pedicelled spikelets laterally compressed; gl. I 

 with the margin on one side indexed aud broadly winged, concave, hairy ; gl. IV 

 usually bisexual. 



15. I. Xiisboae, Hook. f. ; stem creeping below, leaves oblong acute 

 and open sheaths villously tomentose, spikes 2 softly tomentose, gl. I of 

 sessile spikelets oblong 2-fid convex keels with broad auricular ciliate wings, 

 II coriaceous scabridly awned keel winged above the middle, IV oblong, 

 obtusely 2-lobed, awn slender inserted between the rounded lobes. 



NORTH CANARA, Lisloa. 



Stem very stout, rooting at the thickened nodes ; branches ascending 8-14 in., 

 glabrous. Leaves on the creeping stem 1-2 in., closely imbricating in two series, 

 the blades reflexed at right angles to the erect short open sheaths, softly tomentose 

 on both surfaces ; lower sheaths ^-1 in., villous ; ligule short, bearded with very 

 long hairs. Spikes 2 in., joints and pedicels about half as long as the spikelets, stout, 

 concavo-convex, shortly villous, truncate. Sessile spikelets % in., callus very large, 

 glabrous ; gl. I thickly coriaceous, dorsally convex, ciliate above the middle, margins 

 broadly incurved below the middle; II rather longer, rigid, dorsally rounded below 

 the wing; III ovate-oblong, obtuse, margins ciliate, paleate, male; palea chartaceous, 

 obovate, 2-nerved, nerves meeting at the tip with very broad hyaline wings above 

 the middle ; IV = | II, 3-nerved below the middle, asvn about twice as long as 

 the spikelet ; palea lanceolate, nerves ciliate. Pedicelled spikelets laterally com- 

 pressed ; gl. I convex, broadly winged, villous ; IV shortly awned or awnless. The 

 habit of the only good specimen I have seen is very peculiar. 



16. X. ciliare, Retz. Obs. vi. 36; erect or decumbent below, leaves 

 linear, spikes 2-3 villous, gl. I oblong or obovate-oblong convex 5-7-nerved 

 2-lobed or 2-fid from the keels ending in 2 terminal wings, II acuminate 

 or awned dorsally rounded keeled and winged aljove the middle, IV ob- 

 ovate-oblong cleft -to the middle awned in the cleft. Kunth Enum. PI. i.
