 {cha/r. reform.) ; tall, slender, leaves veiy narrow, spikes in a small opea 

 subsimple panicle terminating solitary capillary sheathed peduncles,, 

 joints and pedicels clavate shortly silkily ciliate, sessile spikelets lanceolate, 

 gl. I aoamiuate deeply hollowed between the thickened keels, IV very 

 narrow bisetose. 



NoKTH MuNNEPOEB, alt. 3500 ft., Clarke. 



Stem 2-3 ft., sparingly branched upwards, slightly compressed, nodes glabrous. 

 Leaves 6-10 by -^ in., rather coriaceous, smooth, glabrous, nerves close-set, glaucous 

 beneath with prominent midrib ; sheath terete, smooth keeled ; ligule rather long. 

 Spathe 1-24 in., very slender, terete, acuminate. Panicle 1-li in., as broad as long, 

 of few irregular spreading branches. Spikes 4-8, i-J in. long, very shortly stipitate, 

 solitary or 2-3-nate, divaricate or drooping, peduncle and pedicels of spikes smooth, 

 glabrous j joints and pedicels of upper spikelets with irregularly toothed cupular 

 tips; lowest pair of spikelets sometimes imperfect or male. Spikelets 4-6 pairs, 

 ^ in. long, laxly imbricating j sessile, callus shortly softly bearded j gl. I coriaceous, 

 glabrous, shining, margins incurved, keels minutely scaberulous, nerves 0, or one 

 vanishing below the middle ; II acuminate, 3-nerved, keel ciliolate above the 

 middle; III hyaline, orate-oblong, 2-uerved, glabrous; IV as long as III, lobes 

 subulate, awn J-j in., capillary ; palea minute, truncate. Fedicelled spikelets male, 

 gl. I linear-oblong, convex, subacute, 7 -9-nerved; III acuminate, 3-nerved, glabrous j 

 III as in the sessile spikelets ; IV lanceolate. — The figure in Journ. Linn. Soc. gives 

 the habit of the plant, but the description and analysis are very wrong. The former 

 also errs in citing Androp. No. 4, Herb. Ind. or Hf. & T. under A. Munroi, It is 

 A. apricus. 



Subgen. Y. Amphilophis, Trim,. .Spikes 2 or more fascicled or panicled, 

 with many or few joints ; joints and pedicels of npper spikelets narrow, 

 linear, flattened, usually channelled and translucent between the thickened 

 sides along the mesial line, terete and opaque in 21. A. conccmensis, 27. 

 fascicularis, and 28. venustus, tips simply truncate. Sessile spikelets 

 doreally compressed ; callus short; gl. I acutely 2-keeled ; II keeled, awn - 

 less ; III hyaline, epaleate ; IV an awn with the base acute or very rarely 

 dilated and 2-toothed or 2-fld. Fedicelled spikelets usually as long as the 

 sessile, but narrower, many-nerved, and male. 



A. Spikes with many pairs of spikelets. 



* Pedicels of upper spikelets and joints of rachis slender, strongly com- 

 pressed, with thickened margins and translucent centre. 



t Spikes digitate or fascicled, not panicled, lower longer than the 

 rachis of the inflorescence. (See also 24. A. intermedins.)

 not pitted 5-7-nerved more or less appressedly hairy below the middle,
