species, but I liave followed Scribiier, who has examined Haenke's specimen on 

 which the species is based, in reducing Paspalum cartilaginemn Presl to P. scrobi- 

 culatum Linn., as I can detect no characters in the description of tlie former 

 by which it can be satisfactorily distinguished from the latter. I can also 

 see no reason for retaining Paspalum thunhergii Kunth as a distinct species, 

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

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

A much more robust form than the species with larger spikelets, possibly the 

 same as the species described by Forster as Paspalum orbiculare. (P. scrohi-

Hooker f.,** reduces this species to Paspalum scrobiculatum Linn., and perhaps 

 correctly so. I have referred the form with 2-ranked spikelets to Paspalum 

 scrobieulaluiii Linn., and the form witli 4-ranked spikelets to Paspalum longi- 

 foliuni Roxb.
