Mindanao, District of Davao, Mount Apo (1179 Copeland) April, 1904. 
A species peculiar in its axial parts being not polished or shining but 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.

Luzon, Province of Bataan, Mount Mariveles (2082 Borden) September to 
December, 1904; (1116 Whitford ) May, 1905. 
In this species the pinnae are larger than in any other one known from the 
Archipelago, their borders in part nearly entire and in part dentate. 
ANGIOPTERIS Hoffm. 
Angiopteris offers in a still greater degree than Marattia the lack of palpable 
differential- characters, and the differences between the various forms, quite 
distinct to the practiced eye, are difficult to diagnose properly. I believe it 
possible to distinguish the following species :
