pinnae; coarsely, in the lower part obtusely, serrate, and in the large, superficial 
sori — the last an evident adaptation to the climate of the mossy forest. My 
No. 1830, from Daklan, Benguet, differs from the type in having scattered pinna'. 
The following key includes the named species of fichcUolepis at present known 
in the Philippines; 
1. Pinnae narrowed to the base. • 
2. Sori very deeply immersed P. verrucosum 
2. Sori only moderately immersed P. persicaefolviim 
1. Pinnae with broad base. 
2. Lamina hirsute P. heddoviei 
2. Lamina not hirsute. 
3. Pinnae narrowly triangular P. arc/utum 
3. Pinnae not uniformly narrowed trom base to apex. 
4. Sori superficial P. pseudoconnaUtm 
4. Sori more or less immersed. 
5. Epiphytic P. subauriculatuiii. 
5. Terrestrial P. mengtseeiise 
rolypodium persicaefolium Desv. is the plant of Mount Apo, mentioned in my 
Polypodiaceae, p. 123, as P. phlebodioides. 
Polypodium mollicuhim Copel., Perkins Fragmenta, p. 190, non Kunze in 
Linnaea 25: 749, may be a depauperate form of P. beddomei Bakei'. I have now 
more typical material of this species from Lepanto, and a similar or identical plant 
from Mindanao. Cuming 203, determined by Mettenius (Polypodium, p. 81.) 
as P. paUens Bl., probably belongs here. 
Polypodium argutum ^Vall., is common on Mount Data, Piovince of Lepanto,

Luzon, Lepanto, Bagmen, Copeland 1918. Epiphyticum, 1,900 m. s. m. 
This fern belongs to the very natural group including P. sippelU, P. hetero- 
carpum, and P. ensatum; it is readily recognizable by the regularity of arrange- 
ment and size of the sori.
