Nothing like this in the floras of India, China and Japan. The 

 spikelets of this species are far much larger than any of other species. The 

 general aspect of this new grass is entirely that of a species of Calamagrostis ; 

 but the callus at the base of glume III. are in the new one naked or very slightly 

 hairy the character which is, according to HOOKER, assigned to Agrostis.
