O bs.— In the lobule of this species there is one of the most
remarkable contrivances for the entrapping of small insects it is
possible to imagine: on the inner, antieal face of the ntriculate
lobule is a deep longitudinal fold having at the base a sht with
two deourrent wings hanging free within, one slightly concave,
the other p ia n e -th e unwary insect crawling through this slit,
the lid opens with the slight pressure and closes after the
prisoner has been secured; it is no unfrequent thing to bud
the chitinous remains of several of tliese insects within the lobu e.
I t lias not yet been clearly shown whether tlie plant derives
nourishment by the assimilation of these animals, but we may
rest assured that some object is served by this apparatns,_and the
plant may not inaptlv be called an insectivorous hepatic. I he
late Dr. Gottsche was, I believe, the first to publish any notes on
this character; Herrn Jack and Stephani have also written
on it.
This species is a very distinct one, and the only British representative
of the genus.
Hooker says, “Weiss, who first adopted the name, describes
the species with considerable accuracy,” with which opinion I
agree. Nees and Jack seem to think that he had a form of
Marsupella emarginata before him, although Nees has seen specimens
of the true plant from Weiss’s herbarium.
Scopoli’s Jungermania purpurea of 1772 may be the same as
our species, but it is very uncertain. I t may, however, be said
that the description of Jungermania purpurea in Lightfoot’s “ Flora
Sootioa” (1777) is very inaccurate and vague if applied to this
species.
