SPICILJGJUM FllJCUM PHIL/PPINENS/UM NOVAKUM AUT 
IMPERFECTE COGNITARUM. 
By H. Christ. 
{Basel, Switzerland.) 
In tlie collections of Philippine ferns sent ine by FAmer D. Merrill^ 
Botanist, of the Bureau of Science, and by Dr. E. B, Copeland, wliich have 
increased in an imexpected manner since the year 1903, I have distin- 
guished very many forms not considered by Dr. Copdmid in liis papers on 
Philippine ferns,^ and which are not included in my two works on the 
fern flora of the Archipelago.^ 
At the request of Mr. Merrill, I have prepared a list for publication in 
TiiK Philippine Journal of Scieis-ce, containing the diagnoses of those 
specios that appear to me to be undescribed, and observations on others 
which for one reason or another are of special interest. I wish to express 
my sincere thanks to Messrs. Loiter, Copcland and Merrill for having 
with great liberality supplied me with the rich material that has enabled 
me to undertake this work. 
Cuming's collection is the basis of our knowledge of the pteridophyte 
■ flora of the Philippines, and of which /. Smith ^ published a list of 
species, however, unfortunately, containing many almost nomina nuda.
