THE FERNS OF MOUNT PENRISSEN. 
or almost absent; this is succeeded by a zone of smaller 
timber and rocks, on which filmy ferns are especially 
numerous; also in the moss forest above where the trees 
are stunted or of small growth, they become most 
numerous and continue so to the summit, which in the 
case of Penrissen is a plateau with an area of 50 to 
60 acres, but here ferns are conspicuously absent; two 
or three species only are sufficiently hardy to stand the 
exposed situation. 
I have to thank Dr. E. B. Copeland of the College 
of Agriculture, Los Banos for kind help with identifi¬ 
cations and for describing the new species. 
[At Mr. Brooks’ request I have added the names of 
other Penrissen ferns which were collected on that 
mountain by Mr. R. Shelford in May 1899, and by myself 
in November 1909. A list of the former collection was 
given bv Bishop Hose as an appendix to Mr. Shelford’s 
account of his expedition in the Journal of the Straits 
Branch , Royal Asiatic Society , 1910 (No. 33, p. 25). The 
few species taken by myself on Penrissen were identified 
by Dr. E. B. Copeland. Both collections are preserved 
in the Sarawak Museum herbarium. 
These few additions to Mr. Brooks’ list are given in 
square brackets, duly authenticated by the initials of the 
•collector, viz., Air. Shelford or myself].—J. C. Moulton.
