species. 1 > 1 1 1 I have followed Scribner, who has examined Ilaenke's specimen on 

 which the Bpeciea is based, in reducing Paspalum cartilagineum Presl to /'. acrobi-

 assuming that Mes was correct in his identification of some of the specimens 

 referred to that species in Perk. Frag. Fl. Philip. (1904) 141.
