the tip, variable in length, about twice that of gl. II ; calluB bearded ; palea as long 

 as the gl., linear, obtuse, keels nearly smooth, ^niherg linear. Grain narrowly 

 oblong, glabrous, — A yery variable plant in panicle but constant in habit. Jaubert 

 and Spach's figure is of a very starved small form, and I have not found in Jaoque- 

 mont or other specimens the whorl of hairs at the top of the pediqel (base ot gl. I 

 and II) which they represent. The nervation of gl. I and II varies remarkably. I 

 find both 3-nerved in Sikkim specimens, both 5-nerfed in many Western Himalayan ; 

 both sub 7-nerved in Knnawur ones j both 4-nerved in Simla ones j I S-nerved, II 

 S-nerved in some Western j I 5-nerved, II 7-nerved in Garwbal j I 5-nerved and II 

 sub 6-nerved in Jacquemont's n. 260, in which the awn is twisted to the tip ; both 

 are very sparsely hairy in a few specimens. The lower sheaths are villous in Simla 

 (Hattn) specimens.

Possibly a form of D. cacJiemyriana, but the characters are marked. The 

 specimens are curved in a semi-circle, no doubt from growing amongst rocks, as 

 was the case with Calamagrostis tripilifera, var. (p. 262).
