Perennial. Stem 2-3 ft., erect, not or rarely branched ; nodes glabrous. Leaves 

 3-5 by - in., thin, flat, glabrous, as are the sheaths; ligule a few hairs. 

 Panicle 3-4 in. long and broad, very lax, open, with few scattered brownish or 

 grfenish spikelets; branches branchlets and pedicels perfectly smooth, gl., I II & 

 III membranous; IV thinly coriaceous, sessile. I find no trace of a palea in gl. Ill 

 of any specimen. No other species of this group has sparsely pubescent spikelets, 

 except var. /3 of P. maximum.

Hotter hilly parts of INDTA, from the lower Himalaya in Garwhal, Duthie, to

 Malaya, China, Philippines. 



Perennial. Stem 3-4 ft. or more, smooth, hard, sparingly branched. Leaves 

 5-7 by f-li in., thin, glabrous or pilose, smooth or scaberulous beneath, striato, 

 base ciliate, midrib sometimes excentric ; sheath glabrous or pubescent, mouth hairy ; 

 ligule obscure. Panicle 8-18 by 8-10 in.; branches whorled or alternate, axils 

 sometimes glandular, lower strict 'and unbranched from 13 in. Spikelets terete, 

 glabrous or faintly hairy ; gl. II fugacious. I do not find gl. IV to have 3 stripes 

 as described and figured by Roxburgh, nor is it as broad as in his figure ; but that 

 the plant I have described is Roxburgh's is confirmed by a specimen so named by 

 himsJf. P. montanum has been referred by Wight to the Sumatran P. notatum, 

 Retz (Obs. iv. 18), but that plant is described as having scabrid branches of the 

 panicle, purple spikelets, and acute glumes. The black spots at the axils of the 

 panicle seen in dried specimens of both species, are probably due to a glandular 

 secretion. Wallich's n. 8739, from Ava, has very long pedicels and broad glumes, 

 and a broader gl. IV, but the latter is narrower than in Roxburgh's figure. Duthie 

 (Grass. N.W. Ind. 5) gives Stewart as authority for this grass being found in 

 marshes near Peshawur, but I suspect that Isachne hirnalaica was taken for it. 



45. P. humidor vim, Ham. in Wall. Cat. n. 8721; tall, slender, 

 leaves linear base narrowly cordate, panicle large Joose, rachis branches 

 and (rather short) pedicels capillary smooth, spikelots -^ in. ellipsoid
