BORNEAN FERNS COLLECTED BY C. J. BROOKS. 
By Edwin Bingham Copeland. 
( From the College of Agriculture, Los Banos, P. I.) 
During the past few years, I have received a number of very interest- 
ing collections of Bornean ferns, part of them from Mr. C. J. Brooks, 
Resident of Bidi, Sarawak, part from the Sarawak Museum. Two papers 
on these ferns have already been published. 1 Additional novelties from 
Mr. Brooks’ collections are presented in the following pages. It is indeed 
a pleasure to work on ferns so amply collected as are most of these, and 
in Cyathea this advantage is especially great.
