Throughout INDIA from the Lower Himalaya southwd. to Burma, and the Malay 

 Peninsula, Andaman Islds., and CEYLON. DISTBIB. China, Malaya. 



Stems 1-2 ft., tufted, nodes glabrous or puberulous. Leaves 4-10 in. ; ligule 

 short. Spikes 1-3 in., pale yellow; joints = spikelets, very stout, ciliate. Spike- 

 lets |-i in., pale yellow j gl. I veined in the upper membranous third; ridges of 

 lower often imbricating like folds ; II acute, keeled, scaberulous ; III lanceolate, 

 acute, hyaline, paleate j IV nearly= II ; awn short or long, very sleuder, glistening, 

 palea ovate-lanceolate. Pedicelled spikelets like the sessile, or imperfect. Hackel 

 has 3 vars., but I fail to limit them with copious suites of specimens. There 

 are, however, two recognizable forms ; one with glabrous joints and pedicels, a 

 glabrous or shortly hairy callus, and imperfect awn, the other with more ciliate 

 nodes and pedicels, a more bearded callus and longer awn. 



3. I. magnum, Uendle in Journ. Bot. xxxii. (1894) 102 ; tall, stout, 

 leaves linear-lanceolate from a narrow base, spikes 2 appressed 4-7 in. 

 nearly glabrous, gl. I of sessile spikelet oblong-lanceolate very coriaceous 

 and deeply transversely channelled below the middle thinner above and 

 3-5-nerved with one keel narrowly winged, IV ovate-lanceolate entire 

 apiculate awn 0. 



SINGAPORE ; at Blakan Mate, Feilding. 



Stem 6 ft., branched above ; branches slender, nodes hairy. Leaves 12-20 in., 

 finely acuminate, glabrous above, sparsely hairy beneath ; sheaths above villous and 

 scabrid; ligule - in., 2-auricled. Spikes stout, pale; joints 3-gonous, ciliolate on 

 the outer angle, = \ shorter than the sessile spikelet, tips very shortly bearded ; 

 pedicel of upper spikelet very short stout. Sessile spikelets % in., oblong, convex, 

 pale yellowish polished, tumid between the transverse channels ; II coriaceous, acutely 

 keeled, margins incurved ; III lanceolate, acuminate, hyaline, 3-nerved, paleate, palea 

 as loug 2-nerved ; IV rather shorter, hyaline, ovate-lanceolate, 3-nerved ; palea as 

 long, narrowly lanceolate, 2-nerved. Pedicelled spikelet as loug as the sessile, 

 obliquely convolute, inner margin with 2-3 nodules, outer narrowly winged. 



4. I. xnolle, HooJc.f. ; tall, stout, branched, leaves sessile, spikes 1-2 

 stout densely silkily villous with white hairs, joints broad half as long as 

 the spikelets, gl. 1 broadly ovate-oblong obtuse smooth dorsally villous 

 all over many-nerved, II obtuse silky keel narrowly winged from the 

 middle upwards, IV shorter cleft to the middle, lobes acuminate ciliate, 

 awn geniculately inserted at the cleft.. I. aristatum var. intermedium,

The CONCAN? Herb. Dalzell. CENTHAL PROVINCES; Chanda district, Duthie. 



Stem 3-4 ft., soft, solid, quite smooth, leafy. Leaves 6-10 by $~4 in., finely 

 acuminate, base rounded and cordate, sparsely hairy on both surfaces ; sheaths 4-6 in., 

 smooth, glabrous or sparingly hairy above, mouth villous. Spikes axillary and 

 terminal, 3-5 in. ; joints stout, 3-gonous or concavo-convex, ciliate, tips truncate. 

 Spikelets %-% in. ; callus very short, broad ; gl. I thinly coriaceous, margins narrowly 

 incurved obscurely waved at the base ; II chartaceous, wing ciliolate, margins ciliate ; 



III hyaline, ovate, obtuse, 3-nerved, ciliate; palea as long, narrower, obtuse, 2-nerved; 



IV about 3 shorter than III, awn 2-3 times as long as the gls., golden yellow and 

 shining with a brown column ; palea like that of III but smaller. Upper spikelet 

 smaller than the lower, awnless, pedicel = $ of lower spikelet.
