inches long; the sori large, oblong, parallel with and in & 
row on each side of the mid.rib I have not had the 
opportunity of examining this Fern, and therefore place it 
here on the supposition that the vernation is articulate, 
In the “Species Filicum,” P, terminales, P. peltedia, and 
P. longipes, are united under the original name of Poly. 
podium Phymatodes, but having observed them for many 
years under cultivation, I have been led to consider 
them to be as good species as many others described in the 
“Species Filicum.”

Polypodium sp., auct. ; Hook. Sp. Fil. 
Surculum slender, elongating. Fronds simple, pinnatifid,

Oss.—In general habit the species of this genus are 
similar to Phymatodes, but the well-defined costsform 
veins, thickened and notched margin, marks them as 
being worthy of being adopted as a distinct group; it 
consists of about a dozen species, all natives of India, 
.. Malay, and other tropical islands.
