840 LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 45 
Previously collected here by Copeland 1018 and 1532, and 
by Williams 2477. 
Polypodium obliquatum BI. 
On mossy trunks, Mt. Apo, alt. 1750 m., No. 11422.* 
This is probably the commonest fern of the Philippines 
mossy forest, and is regularly encountered throughout the 
archipelago. 
Malaya to India. 
Polypodim venulosum BI. (P. erythrotrichum Copel.) 
On mossy trunks, Mt. Apo, alt. 1800 m., No. 11521. 
"Ooleli." The reduction of P. erythrotrichum is made by com- 
parison with specimens collected and determined by Raciborski. 
Mindanao, Mindoro, Luzon, in the mossy forest. 
Malaya. 
Polypodium subfalcatum Bl. 
Small tufts on mossy trunks, Mt. Apo, alt. 1800 m., No. 
11537. ''Captian." P. macrum Copel. is probably a peculiarly 
delicate form of this. . 
Northward to Mt. Banajao. 
Malaya to India and China. 
Polypodium mollicomum Ns. et Bl. (including P. fus- 
catum Bl.) 
Elmer’s collection is very complete, and includes what 
I believe to be typical specimens of P. mollicomum and of 
P. fuscatum. No line can be drawn between the two. 
No. 11474. In small tufts on mossy trunks, Mt. Apo, 
alt. 1800 m. ''Sigbut." 
No. 11360. It is a smaller and decidedly more rigid 
plant, which I do not care to describe as distinct; Mt. Apo, 
alt. 1500 m. ''Rominga." — 
No. 11474." On dead mossy limbs, Mt. Apo, alt. 1800 m. _
