Palawan (742, 862 Foxworthy ) March, April, 1906. Mindanao, Province 
of Surigao, Surigao (26 Bolster) March, 1906, the latter very small, about 23 
cm. high, resembling a specimen from Borneo leg. Ridley, 1901. 
This presents the appearance of a well-established species. It is large, fascic- 
ulate, with a definitely established dimorphism, and is readily recognizable by 
its numerous pectinate lanceolate pinnae, stipitate and manifestly hastate at 
the base, the nerves forming several areolae. In some respects it resembles 
Egenolfia appendiculata and might be mistaken for that species except that the 
bases of the pinnae are equal.

This is a reduced form of D. Merrillii with obtuse pinnae, more simple venation 
and the pinnae auriculate only anteriorly.

fronde oblonga 16 ad 24 cm. longa, 4 ad 6 cm. lata acuminata et in

A small plant resembling D. Amboinensis (Willd. Sp. PI. 5: 228, Aspidium ) , 
but even smaller than that species, with numerous obtuse auricles on the stipe, 
narrow pinnae which are scarcely incised, and more numerous sori.

Samar (327 ? Cuming) 1836-40. The interrogation point concerns only the 
number in Cuming’s series, and not the plant itself, the identity of which is 
incontestable. 
I do not consider that the elongated sori and their arrangement in horizontal 
lines merits the generic separation of this form, as in all other respects it is a 
true N ephrodium.
