NEW PHILIPPINE FERNS. 



By Edwin Bingham Copeland. 

 (From the Bureau of Education, Manila, P. 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 Polypodiacese of the Philippine Islands. 1 Many more 

 probably, 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 descriptions. The new species are represented 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 Nephrodium are reported here, as our collections of this 

 great genus are being worked over by Christ for publication in the near 

 future.
