NEW PHILIPPINE FERNS. 
By Edwin Bingham Copeland. 
(From the Bureau of Education, Manila, F. I.) 
The ferns herein described as new, or reported as additions to the 
Philippine flora, have, almost without exception, been collected since the 
preparation of the Polypodiacefe of the Philippine Islands.^ Many more 
probahly, but not yet certainly, new species are held for further study; of 
a number of other new species the material collected is inadequate for 
good descrijitions. The new species are re])resented in the herbarium 
of the Bureau of Science and in that of the author. It is a pleasure to 
acknowledge valuable assistance from Dr. Christ, of Basel, Switzerland. 
No additions to N Gplirodwm are reported here, as our collections of this 
' great genus are being worked over by Christ for publication in the near 
future.
