122 COPELAND. 
Dr. H, Christ is making a special study of our collections of Dryopteris 
{Neplirodiam), and most of our Selaginella material is in the hands 
of Professor Hieronymus; therefore I have not undertaken to determine 
MerrilVs material in either of the above genera. Of Dryopteris about 
10 species are represented, and of Selaginella, about 6 species. Of the 
remaining Pteridophjtes 20 species and varieties are described as new, 
and among these are some which emphasize the position of the Philip- 
pines as the richest region in the World in Polypodiunt and in several 
related genera such as Prosaptia, Acrosorus and Plagiogyrla. 
POLYPODIACEJ]. 
ACROPHORUS Presl. 
+ 
Acrophorus stipellatus (Wall.) Moore. 
On ridges in the mossy forest at 1,300 ni. alt. (No. 5952). 
Already collected in the Philippines on Mount Apo, Mindanao, and on Mount 
Duta, Luzon. 
India, Malaya. 
MONACHOSORUM Kunze. 
Monachosorum subdigitatum (Bl.) Kulm. 
On ridges in the mossy forest at 1,300 m. alt. (No. 6164). 
Previously knowTi in the Philippines only from Mount Apo, Mindanao. 
ASPIDIUM Swartz. 
Aspidium leuzeanum (Gaudich.) Kunze. 
In a damp ravine at 150 m. alt. (No. 5876). 
Luzon and southward, variable, not common. 
India to Polynesia. 
Aspidium Barberi (Hook.) Copel. 
Terrestrial in forests at 300 m. alt. (No. 5875), 
Luzon. Majaijai {Loher). 
Malaya. 
A probable relative of A. polymorphum, with the form of A. pachyphyllum and 
unlike any other Aspidium, known to me, in the very long free excurrent included 
veinlets. 
Aspidium polymorphum Wall. 
On shaded cliffs at 150 m. alt. (No. 5874). 
Throughout the Philippines and worthy of its name, 
India to Malaya. 
Aspidium macrodon (Reinw.) Keys. 
On boulders in humid forests at 150 m. alt. (No. 5873). 
r 
Luzon, Mindoio. 
Malaya, Fiji. 
Aspidium Copelandii C. Chr. {A, hcterodon Copel.). 
Terrestrial in ridge forests at 700 m. alt. (No. 5872). 
Very doubtfully distinct from Asjndiiim decurrens Presl, and the relative ranges 
of the two species uncertain, because many of the specimens in the herbarium are 
without stems.
