Mindanao, District of Davao, Mount Apo (1170 Vopeland) April, 1904. 
A species peculiar in its axial parts being not polislied or sinning Init dull, 
dark colored, rough, and with numerous scales. The denticulation is very open 
and the synangia are smaller than in any other species known from the 
Archipelago.

In this spefies the pinnir are larger than in any other one known from the 
Archipelago, their borders in part nearly entire and in part dentate.

Angioptcris offers in a still greater degree than Marattia the lack of |»iilpable 
difrerentiai characters, and the differences between the various forms, quite 
distinct to the practiced eye, arc difficult to diagnose properly. I believe it 
possible to distinguish the following species:
