tliin and diaphanous texture and small irregular sori which are not immersed 
in pits. 
83. Polypodium palmatum Blume Fil. Jav. 150. 
CopeJand^ credits Polypodium trifldum Don to the Pliilippines, but as he 
presumes, 1. c, all the specimens from the Archipelago are referable to P. 
palmatum Blume, also those that I have cited previously for P. trifidumr 
Typical P. trifidum is an essentially Chinese species which does not extend to 
-Tapan nor to the Malayan Archipelago.

Mindanao, Province of Zamboanga, San Ramon (1585 Copeland) January, 
1905, alt. 175 m. 
A species related to P. longifolium Mett., which is also found in the Archipelago^ 
Palawan (631 Foa^worthy) April, 190G, differing from the latter in its firm 
texture, pale color, shining, the fronds narrower and long acuminate at the 
apex, the margins inflexed and the sori much elongated. P. longifolium is 
broader, the apex not sharp, the texture less firm, opaque, dark brown when 
dry, the sori often more rounded.
