DOUBTFUL AND EXCLUDED SPECIES 



Panicum elythroblepharum Steud.; F.-Vill. Novis. App. (1882) 311. 



Panicum stipatum Presl Rel. Haenk. 1 (1828) 297; F.-Vill. Novis. App.

"Hab. in Mexico, Luzon?" Presl. This is the American Digitaria setosa 

 Desv. fide Scribner in Rept. Mo. Bot. Gard. 10 (1899) 49. 



Paspalum filiforme Sw.; Presl Rel. Haenk. 1 (1828) 297; F.-Vill. Novis.

"Hab. in Luzonia ? Mexico" Presl. This is the American Digitaria fili- 

 forme Delile fide Scribner in Rept. Mo. Bot. Gard. 10 (1899) 49. 



Paspalum molle Presl Rel. Haenk. 1 (1828) 213 = Paspalum mollicomum

Bot. Gard. 10 (1899) 50. * 



"Hab. in Luzonia" Presl. This was considered by Scribner to be a valid 



species, but Presl's description does not apply to any Philippine form known 



to me and I suspect that the type was an American, not a Philippine plant.
