and to Deyeuxia, those with both a villous callus and the rachilla elongate beyond 

 gl. Ill and (with a few exceptions) penicillate. I know of no species of Agrostis 

 with the last-mentioned character of Deyeuxia, but there are species of Agrostis 

 with longer hairs than normal in the callus, and of Calamagrostis with shorter hairs 

 than normal ; there are also species of the latter genus with a minute elongation of 

 the rachilla, and of Deyeuxia in which that organ is short. There is no Indian 

 Agrostis except A. myriantha with the tall coarse habit of several species of Calama- 

 grostis and Deyeuxia, but many species of these two genera have the slender habit 

 of Agrostis, and can only be distinguished from it by the minute characters given 

 above. The species of Calamagrostis with the gl. Ill hairy all over form a peculiar 

 section, well limited by this character; their habit is altogether that of Agrostis. 



* Palea half as long as gl. Ill or longer, rarely minute.

 the " Kew Index," for many apply to obscure forms or varieties none of which occur 

 in India; except var. stolonifera, (A. stolonifera, Host Gram. Austr. t. 57) of 

 which there are Nilghiri specimens, but no doubt introduced. The awned variety 

 y. aristata, Boiss. 1. c., a widely distributed European, American, and Asiatic plant is 

 noted as Tibetan by Boissier, but I have seen no specimens. It is a tall form with 

 broad leaves. Boissier describes the branches of the panicle as rough in alba, but 

 they are smooth in all Indian specimens. Wight's n. 1746 has a minute palea.
