H a b . Jamaica. Dr MKadyen.— I also possess specimens of the same plant, given by
the late Mr Donn of Cambridge to Dr Lindley. The indusia are certainly cordate, fixed
by the very deep sinus ; not orbicular and peltate as figured in leones Filicum.

* So named in compliment to Dr M'Fadycn, F .L .S . of Kingston, Jamaica, author of a Flora of
Jamaica, to whom I am indebted for a very extensive collection of planis, including many Ferns, (this
one among them,) and to whom I owe far greater obligations for his unremitting attentions to a beloved
son, who fell a sacrifice to yellow fever, while under his hosiiitable roof.
