ADDITIONS TO THE BORNEAN FERN FLORA.

(From the College of Agriculture, Los Bajos, P. I.) 
Dryopteris glabrior Copel. spec. nova. 
A D. crenata (Forst.) O. K. fronde majore graciliore, multo laxiore, 
ubique multo glabriore, soris minoribus differt. 
Gunong Kapor, near Bidi, leg. C. J. Brooks. 
D. crenata is unknown in Borneo, While the differences between this species 
and D. crenata are all only of degree, they are so marked that they justify treating 
the two plants as specifically distinct. D. glabrior is the more primitive of 
the two. 
Dryopteris penangiana (Hook.) C. Chr. var. calvescens (Christ) (D. 
ferox var. calvescens Christ). 
Bengkarum, near summit, leg. C. J. Brooks, No. 27. 
The species is known from continental Asia; and this form, which in spite 
of its stature is more nearly related to this species than to D. feroxw, has been 
found in Mindanao and Negros.
