T h e writer of this article was formerly sceptical concerning
the claims of this species, and has thus been induced
to subject it to very rigorous investigation, for which he
has enjoyed excellent opportunities; the plant growing in
great luxuriance and perfection near Frodsham in Cheshire,
whence the specimens figured were obtained in March last.
He has obtained permission from the discoverer, Dr. Taylor
of Dunkerron, to describe it for this work, with the
hope of more readily dispelling similar doubts elsewhere.
Considerable resemblance exists between this species
and J. epiphylla; so much so, that a detailed description is
considered unnecessary. The points of difference will be
chiefly discussed here. J. calycina differs in the shape of
the frond, which is much narrower, more elongated, with
