SIKKIM and BHOTAN HIMALAYA, alt. 9500-11,000 ft., Griffith's Collectors, 

 Kurz, &c. 



A gregarious shrub 8-12 ft. high, very closely allied to A. spo.thifiora, of which 

 it is the Eastern representative, distinguished from that species in having broader 

 bracts enclosing more spikelets, shorter leaves, a hairy callus below the longer petiole, 

 longer mucros of the flg. gls. and a long more acuminate palea. It is readily 

 recognized by its yellow stems and reddish branchlets. The stems are leafing only, 

 or flowering only, or both.

Tall, shrubby. Stem ^-f in. diam., young smooth, old scurfy-white, often striped 

 yellow and green ; nodes raised, base of sheath persistent ; internodes 8-15 in., walls 

 ^- in. thick ; branches many at the nodes with bracteate sheaths. Stem- sheaths 812 

 by 2-3 in. ; ligule narrow, dark, hairy. Leaves smooth on both sides, ligule rounded 

 hairy. Rachis of raceme flexuous, flattened. Spikelets with a terminal free rachilla, 

 and a ring of hairs below the flg. gl. ; keels of palea glabrous except at the tip, 

 1-nerved on each side. The small sheaths enclosing short sinuous racemes, and the 

 absence of transverse nervules in the leaves characterize this species.
