Perennial. Stem 3-5 ft., stout or slender, slightly flattened on one side; noae« 

 glabrous or hairy. Leaves 6-18 by \~\ in., flat, glaucous, setaceously acuminate, 

 ciliate towards the base ; sheath hairy at the top; ligule very short, truncate. Fanxdi 

 very variable in form and density, pyramidal thyrsiforra or subcorymhose, rachis 

 and branches glabrous the latter usually in opposite pairs ; spikes variable ju 

 length. SpiJcelets pale green or purplish; gl, I rather thin, obtuse or narrowly 

 truncate, 4-7-nerved ; II oblong or lanceolate, 3-nerved, keel smooth, margins 

 glabrous; III = ^ I, oblong, glabrous, nerveless; IV" a slender awn, l-lj in. lon(f» 

 palea 0. — Fedicelled spikelets linear-oblong or -lanceolate ; gl. I 5-9-nerved, glabrous, 

 keels ciliolate ; II lanceolate, 3-nerved, ciliate; III shorter, oblong, glabrous, nen^e* 

 less; IV 0.— A variable phmt, nearest perhaps to a Kuntzeanus from >yhich w 

 paniculate inflorescence and smaller spikelets distinguish it. In some specimens tbe 

 spikes are reduced to a few, and then the paniculate character disappears. 



The following are Hackel's varieties of the Indian plant, which a larger senes 



ipecimens than he had access to tends to invalidate. — Roxburgh's A. puncta*^*

 good original drawings, do not fall under any of Ilackcl's vars. Both have pit****

 long quite simple spikes on a rather short rachis. Hackel has given a plant ot 

 Duthie's from Simla, 7-8000 ft., the mss. name of var, himalai/ensis ; it is, I thm*,
