 3-6, 2-4 in. long, very slender, pale green or yellowish brown ; joints compressed, 

 broader upwards, ciliate. Q-lumes usually widely spreading ; I subacute or narrowly 

 truncate, keels scaberulous or shortly ciliate above ; II with villous margins towards 

 the mucronate or aristulate tip ; IV very minute, rounded. Anthers linear, half

 2^-5 by \T in., flat, thin, sparsely ciliate chiefly towards the base, tip capillary, 

 margins smooth, base a mere point, midrib slender; sheath very slender; ligule 

 minute. Spikes 2-l in., erect, flexuous, pale green, joints truncate. Gl. I. of sessile 

 spikelet 0-5-nerved, tip more or less 2-toothed; II obtuse, 3-nerved ; IV awn capil-

 pressed, spikelets -| in. lanceolate, gl. I narrow subtruncate keels

TEMPERATE HIMALAYA ; Simla, Gamble ; Nepal, Wallich ; Sikkim, alt. 4-7000 

 ft., J.D.H., Clarke. KHASIA HILLS, alt. 4-5000 ft. DISTKIB. China, Japan. 



Leaves narrowed to the base, flaccid, smooth or subscaberulous. Spikes 1-3 in., 

 not fascicled, green, joints more or less ciliate, hardly clavate ; callus naked ; gl. I 

 concave dorsally, 2 6-nerved, nerves sometimes anastomosing ; II 1 3-nerved ; awn of 

 IV sometimes capillary, and very short (var. Willdenowiana, Hack.) ; sometimes (var. 

 ffenuina, Hack.) it is longer, stouter, with a twisted base. Very variable in size ; smiiH 

 Nepal specimens have filiform stems 6-12 in., with oblong-lanceolate acute leaves au 

 inch long, and solitary spikt-s ; some large Khasian specimens have stouter much 

 branched stems 2 -3 ft. long, with acuminate linear-lanceolate leaves 3-6 in. long, 

 and 6-7 spikes. The minute persistent didymous anthers are those of Arthrayon t 

 and differ from those of all other Indian species of Pollinia* 



*** Diandrous, anthers linear-oblong.
