It agrees also with Blume^s description'' in the."Venis jam conspicuis, marginem 
fere attingentibus, semper furcatis, ramulo una plerumque item furcato." Since 
even a very considerable difference in the degree of pubescence would not be 
generally received as a good specific character, I treat tliis as a variety. However, 
^ it is unlike the plant already determined as Polypodium sctosum from Mount 
Mariveles, and neither is it indentical with the typical Afount Apo material. 
A most interesting variation is the occurrence of anastomosing veins in certain 
plants with rather ample fronds.

McrrilVs material is very constant in the characteristic sparse distribution 
of the sori. In tlie insertion these are as figured by Hooker^ not as described 
I . by Christ, in P. sessilifoHum, being dorsal on the vein, which is very remarkable 
considering the deep iunuersion. 
Polypodium cucullatum X^es et Bl. 
On mossy trunks in the ridge forest, 1,150 to 1,400 m. alt. (No. 5968). 
Common in the Philippines. 
Ceylon to New Calodonia.

Except for a few intermediate forms, this would be regarded as a distinct 
new species, and might be considered as intermediate between Eupohjporlhun 
and Calynimodon, but it is probably derived from the latter and purely local. 
Polypodium gracillimum Copel. 
Epiphytic on mossy trunks at 1,400 m. alt. (No. 5858). 
Throughout the Philippines. 
Polypodium moHicomum Bl. . 
On mossy trees, exposed ridges at 1,400 m. alt. (Xo. 5973). 
Previous Piiilippine collections of this species are Yoder'a from Panay, and 
MerriWs from ^Mount Halcon, Mindoro. 
Malaya. 
While most of Mcn-iIVs copious material is typical P. moUk'otnut)i, it is 
variable in size and in tlie length of the stipe, and seems to me to intergrade 
completely with specimens, that by themselves, would be referred to P. fuscatum 
Bl. The latter thus becomes a synonym.
