being fertile. The occurrence of sterile and fertile pinnae on the same frond is 
hitlierto unknown in the genus. It is possibly abnormal in this case, but I 
believe the species is sufficiently distinct without this character. 
Athyrium vestitum (Pr.) Milde? 
Sarawak, Bidi, on limestone, leg. Broohs. 
This plant differs from Cuming's, collected in Samar, in that the pinnae are 
abruptly contracted and then acute, instead of obtuse, that they are widest two- 
thirds of the way to the apex, instead of just above the base, that the lowest pin- 
nules are notably reduced, that the sori are shorter (perhaps due to age or 
condition) and especially in the remarkable black border of the scales, which 
is several cells deep: in our A. vestitum no large scales are present, and there 
is at most a black border 1 cell wide. 
Tlie real A. vestitum of Samar will probably be collected again in the near 
future, and with more complete material of it, including the rliizome and stipe, 
it will be easy to decide positively whether or not the Sarawak plant should be 
regarded as distinct.

The very large basal prongs give this fern a most bizarre aspect. 
Lindsaya Hewittii Copel. spec. nova. (Plate V.)

The nearest relative of this species, as is shown especially by the position and 
appearance of the sorus, is L. orhiculata (Lam.) Mett.; superficially it more 
strongly suggests L. davallioides or L. rigida; or still more strongly the American 
L. stricta. 
Tapeinidium pinnatum (Cav.) C-Chr. 
Specimens collected by Foxxcorthy, Nos. 189, 209, differ uniformly from those 
of the Philippines in being deltoid in outline.
