Tolypodium—Polypody. Flexile—Bending.
A V E R Y pretty and distinct hardy British Fern , more slender
and flaccid than Polypodium alpestre, narrower fronded,
the pinnæ being shorter, and the pinnules much less numerous.
Pinnæ brief, spreading, deflexed, having six to eight pairs
of pinnules. Pinnules oblong and narrowing below; distantly
toothed.
Stipes very brief.
Sori chiefly at the base of the frond, six or eight on a
pinnule. Apex barren.
Length of frond from six to sixteen inches.
Found in Glen Prosen, Clova Mountains, by Mr. Backhouse.
For fronds my thanks are due to Mr. Stansfield, of the Vale
Gardens, Todmorden.
