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

 with the last-mentioned character of Deyeuxia^ but there are species of AgrosUs 

 with longer hairs than normal in the callus, and of Calamagrosiis with shorter haiT^ 

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

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

 Agrostis except A. mt/riantha witli the tall coarse habit of several species o( Calam- 

 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 giveo 

 above. Tiie species of Calamagrosiis with the gl. Ill hairy all over form a peculiar 

 section, well limited by this character; their habit is altogether that oi AgrosUs.
