MlNDOBO, ad montem Halcon; de ramis muscosis pendente. Merritt. 



A probable relative of P. solidum Mett., and P. corticolum C. Chr. (P. glan- 

 dulosum Hook.) ; but longer, narrower, less coriaceous than the former and not 

 glabrous; larger than the latter, and essentially different in the position of the 

 sori, which are subterminal on the veinlets of P. corticolum, but basal on these 

 of P. Mcrritti.

This is in the group of P. neglectum 151., and P. Nummularium Mett. It may 

 be the P. rhynchophyllum of Christ (Bull. Herb. Boiss. 6 (1898) 199) but not 

 of Hooker Sp. Fil. 1 : G5. It is decidedly smaller than this Indian fern, with 

 rather immersed sori not confined to the upper part of the frond, and larger 

 areoliB with excurrent veinlets. 



Polypodium Nummularium Mett. I am unable to distinguish P. hammatisorum 

 Harrington. The plant is a Phymatodes, rather than a Qoniophleoium.

This species was prepared for publication in my preceding paper; but, after 

 the galley proof was corrected, I received a letter from Dr. Christ identifying 

 Elmer's 6408 as P. mengtzeense. Having only the description of P. mengtzcensc,
