plant, not noticed in any of our local Floras, has been
found about London, as well as in Sussex, and the north.
It grows in damp shady places, and is said by Dillenius to
flourish from March to July. Mr. E. Forster gathered our specimens
in the fields at Walthamstow on the 1st of October.
The fronds are attached by annual fibrous roots to the
moist earth, and spread in a circular manner. Their centre
is depressed or concave; their margin lobed, and more or
Jess deeply sinuated or pinnatifid, the segments oblong and
obtuse; The colour is a bright shining green. Several dots
appear on the surface, which are the male flowers, in the form
of black imbedded warts, with a torn margin. The capsules
arise like copious blades of grass, each from a sheath, and are
cylindrical, tipped with a veil when young, bursting when
ripe into 2 valves with a parallel partition. Each cell contains
many black rough seeds, fixed to elastic stalks.
