62. A. nitidulus, Hook. f. annual, very slender, branched, leafy, 

 leaves long narrow flaccid scaberulous base contracted, spikes very few- 

 very unequal on a long capillary peduncle white, rachis tenacious, sessile 

 spikelets ovate-oblong 9-nerved dorsally flat glabrous or scabrid towards 

 the hyaline truncate tip, keels ciliate towards the tip, II 5-7-nerved 

 acuminate, IV short broadly 2-lobed, awn very slender. 



N.W. HIMALAYA; on the Sewalik Hills; and Chanda in the CENTRAL PRO- 

 VINCES, Duthie. 



Stems 3-4 ft., loosely tufted, very slender from the naked base upwards, nodes 

 glabrous. Leaves 8-12 by i- in., acuminate, thin, margins scaberulous ciliate 

 towards the base, midrib slender smooth, nerves very slender ; sheath smooth ; 

 ligule oblong, membranous, ciliate. Spikes quite white, tbe terminal on the peduncle 

 1-1 in., lower rather distant, sessile, much shorter; peduncle 4-8 in. ; joints and 

 pedicels = about the sessile spikelet, very slender, ciliate with long white silky 

 hairs, tips truncate, joints terete, pedicels flattened (almost as in Sect. AmphHophis). 

 Spikelets few, in rather distant pairs, hornogamous pairs one or two. Sessile spike- 

 lets in., callus very short, stellately bearded with white hairs ; gl. I thin, greenish, 

 dorsally polished, margins narrowly incurved; II chartaceous lanceolate, 5-7-nerved, 

 margins broadly incurved, ciliate; III smaller, lanceolate, 2-nerved. ciliate; lobes 

 of IV ovate, acute, divergent, ciliate ; awn about | in., slender, column quite smooth. 

 Anthers short. Pedicelled spikelets rather longer than the sessile, narrowly 

 lanceolate, green, neuter ; gl. I membranous, 9-nerved, glabrous, margins incurved, 

 ciliate towards the tip only ; II 7-nerved ; III rudimentary or 0. 



Subgen. X. HETEROPOGON, Hack. Spikes solitary, joints many and 

 pedicels not channelled ; lowest pairs or 2-8 pairs of spikelets closely im- 

 bricate, male or neuter. Sessile spikelets subcylindric, gl. I sabcylindric 

 or oblong, II obtusely keeled, not avvned ; I [I hyaline; IV a long awn. 

 with a stout column and often a hyaline base. Pedicelled spikelets very 

 unlike the sessile and concealing them. 



* Ligule membranous ; column of awn hirsute ; callus of sessile fern, 

 spikelets pungent.
