i n c t .
I t was raised from spores in 1858, in the fernery of Messrs.
Stansfield, Todmorden, near Manchester.
I t is easily distinguished from Polypodium flexile, by its
densely set and laciniated pinnæ.
The pinnæ are recurved towards the base of the stipes, brief,
and rounded at the end; the pinnules decurrent, variously
toothed or laciniated, and densely set.
Veins branched; venules simply furcate.
Sori medial and covered with an indusium, as in the
A th y rium family; indeed this and the normal form seem to be
as closely connected with Athijrium as with Polypodium.
L ength of frond from four to nine inches, and about an
inch broad.
^^For fronds my thanks are due to Messrs. Stansfield, of
Todmorden.
