 narrow, style ^-i in. long. — A remarkable grass, tbe character and affiuities of which 

 we discussed at length by Hackel, who places it next to Bromus, where it will 

 be found (No. 123) in the clavis of this work, p. 8. The recognition by Dr. 

 otapf of a second species, D. oligostaoh^a, Stapf (Avena oligostacliya, Munro in 

 Journ. Lim. Soc. xviii. (1880) 108, name only, Aitohison I. c. xix. (1882) 193, 

 J- 30) proves the position of the genus to be near Danthonia, where I hud placed it, 

 before its publication by Hackel, when I deferred to that author's high authority.
