Caules 6-8-pollicares, subramosi, undique foliosi. Folia 3-9 lin.

A very remarkable grass, with the habit of an Arthrazon, strongly 

 resembling A. microphyllus, but differing totally from that grass in 

 structure and in the inarticulate fla^^teoed rachis of the simple spike, 

 in the bisexual awned pedioelled spikelet, and in the absence of the third 

 glume of that genus. Unfortunately the specimens are unaccompanied 

 by any note of locality, which is presumably the North-western 

 Himalaya, where Dr. Falcoiaer travelled extensively and collected 

 largely.— J. D. H.
