Our Eragrosiis major would scarcely come under the defi- 

 nition of Briza as given, but authors seem to agree as to the 

 identity of this with Briza Eragrosiis. 



Kuntze (Rev. Gen. p. 774) gives Eragrosiis minor, Host 

 1809=Poa polymorpha, E. Br. ISIO^^E. poceoides^ Beauv. 

 1812=^ JS7. orienialis, Tvin.^^E. Brownei^ Nees, etc; and E. 

 midiifloray AscK^^Poa Eragrosiis^ L. p. p.=Poa miiUiJlora, 

 Forsk. 1775=Poa megasiachya^ Koel. 1802^^£'. major. Host 

 1809=_E7- megasiachya^ Link. etc. 



Under the recent rules adopted by the Botanical Club of 

 the A. A. A. S., the oldest specific name persists under all 

 circumstances. Consequently the name Eragrosiis Era- 

 grosiis must be used for Poa Eragrosiis, L., and Briza 

 Eragrosiis^ L., if it is kept up as a distinct species, would be 

 known as Eragrosiis muliijloray (Forsk.) Asch., provided 

 Dr. Kuntze's statement of synonymy is correct. 



The combination Eragrosiis Eragrosiis was published in 

 Karsten's Deutsche Flora p. 389, 1880—1883, (fide Britton, 

 Bull, Torr. Club, 1893, p. 443). 



The same also occurs in MacMillan's Metaspermae of the 

 Minnesota Yalley, p, 75, as E. eragrosiis (Linn.) [MacMil- 

 lan], but is here applied to Briza Eragrosiis, L, 



However, the combination occurs earlier than either of 

 these. 



Beauvois established the genus Eragrosiis in his Essai 

 Agrost., p. 70, founding it chiefly on Poa Eragrosiis, L. As 

 is his method in this work, he follows the description of new 

 genera by a list of the species to be included, but the latter 

 are still combined with the generic name under which they 

 were formally included. So we find after the above genus: 

 Spec. Poa Cynosuroides? Cyperoides? Eragrostis, ferru- 

 ginea, and four others. 



But under the genus we find a reference to PI. xiv, fig. xi, 



Eragrosi
