Sarawak, Bau, Jebong Valley, on porphyry dyke. Brooks 112. 
In the same general group as the following. More like Dryopteris jacu~ 
losa (Christ) C. Chr. than any other species known to me.

Sarawak, Single, in swamp near foot of mountain. Brooks 110. 
This keys out with van Alderwerelt’s “Malayan Ferns” as his Dyropteris 
sumatrana {Nephrodium violle var. major Bedd.) which he seems not to 
have seen and which has never had an adequate specific diagnosis, and 
may be suspected of being D. stipellata (Bl.) 0. Ktze. J. Smith, in a 
marginal note in his copy of Blume’s “Enumeratio,” construed Aspidium 
stipellatum as A. molle. Dryopteris angustipes is not merely exceedingly 
distinct in appearance from D. parasitica but differs in the character of 
the pubescence from that species to such an extent that Beddome could 
not have placed them together. 
Lomagramma Brooksii Copel. 
Mr. Brooks has sent me a very complete specimen, collected at Bau. It 
has the fertile and sterile fronds distinct, as in other species of the genus. 
The frond of a juvenile plant “which germinates on the limestone and 
may grow in large masses before reaching a trunk, and becoming scandent”, 
has membranaceous, serrate, and very oblique pinnae. Fronds of adult
