scarious ; gl. I often faintly nerved ; II 7-nerved, subaristate ; flg. gls. oblanceolate , 

 hairy below the middle, lobes obtuse ; awn f -1 in., scabrid, obscurely geniculate. Ovary 

 narrow, style | |- in. long. A remarkable grass, the character and affinities of which 

 are discussed at length by Hackel, who places it next to Sromus, where it will 

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

 Stapf of a second species, D. oligostachya, Stapf (Aveua oligostachya, Munro in 

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

 t. 30) proves the position of the genus to be near Danthonia, where I had placed it, 

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