NEW SUMATRAN FERNS 
By E. B. COPELAND 
(From the College of Agriculture, University of the Philippines, 
Los Bavtos, P. I.) 
Mr. Cecil J. Brooks, to whose zeal and skill as a collector 
much of the recently acquired knowledge of the fern flora of 
Borneo is due, is now living at Lebong Tandai, Benkoelen, Su- 
matra. From this locality he recently sent me for determi- 
nation a most interesting collection of 111 specimens from which 
the following fourteen are described as new. There are also 
a considerable number of other additions to the known flora of 
Sumatra. The study of the collection leaves me with the opinion 
that the floras of Borneo and Sumatra are much more closely 
- related than has hitherto been supposed. 
The numbers accompanying the following descriptions are 
those attached to the specimens by Mr. Brooks. The locality 
is given on all labels as “Lebong Tandai, Benkoelen.”

No. 41. “In thick jungle on steep bank of stream. A large fern.” 
The remarkably caudate pinnules give this species a very distinct appear- 
ance.
