It agrees also with Blume’s description 5 in the “Venis jam conspicuis, marginem 
fere attingentibus, semper furcatis, ramulo uno 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 this as a variety. However, 
it is unlike the plant already determined as Polypodium setosum from Mount 
Mariveles, and neither is it indentical with the typical Mount Apo material. 
A most interesting variation is the occurrence of anastomosing veins in certain 
plants with rather ample fronds. 
Polypodium paucisorum Copel. n. sp. (PI. Ill, Fig. B.) 
Species P. subcvenoso Baker affinis illo frondibus graeilioribus et soris 
paucis, remotis, valde immersis distincta. Candice erecto, paleaceo breve ; 
frondibus confertis, sessilibus, 8-12 cm. altis 3-4 mm. latis, subacutis, 
deorsum valde attenuatis, integris, glabris, subcoriaceis ; venulis occultis 
furcatis soris supra valde prominentibus. 
Ad arbores muscosos. 180-240 m. s. m. (No. 5964). 
Merrill’s material is very constant in the characteristic sparse distribution 
of the sori. In the insertion these are as figured by Hooker, not as described 
by Christ, in P. sessilifolium, being dorsal on the vein, which is very remarkable 
considering the deep immersion. 
Polypodium cucullatum Nees 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. 
Polypodium cucullatum var. planum Copel. n. var. 
Typo segmentis planis amplis, proximis, . oblongo-orbicularibus diver- 
sum; soro magno, subsuperficiale. 
Ad arbores muscosos epiphyticum, 900 m. s. m. (No. 5967). 
Except for a. few intermediate forms, this would be regarded as a distinct 
new species, and might be considered as intermediate between Eupolypodium 
and Calymmodon, 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 mollicomum Bl. 
On mossy trees, exposed ridges at 1,400 m. alt. (No. 5973). 
Previous Philippine collections of this species are Yoder’s from Panay, and 
Merritt’s from Mount Hal con, Mindoro. 
Malaya. 
While most of Merrill’s copious material is typical P. mollicomum, it 'is 
variable in size and in the 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.
