Nephrodium pubescens {A sp id ium o f Swartz, and Pobjpodium o f Linn.) is one o f th o se plants the
identity o f which, for want o f a g o od description or figure, must be to us a matter o f some doubt.
The present plant, which is equally with that species a native o f Jamaica, appears to us to agree
sufficiently we ll with th e short characters o f authors. Our description we accompany with a
representation, which, wc trust, will at lea st remove all doubt as to the plant we designate under
this name.
I t b elon g s, indeed, to a tribe or group o f Nephrodium, that is attended with much difficulty in
the discrimination o f the species which compose it, and which can hardly be understood without
accurate figures. I t will rank near to our A sp id ium aculeatum: but is we ll distinguished by its
shorter, more deltoid frond, having the rachis, and nerves, and margins o f th e pinnules clothed with
copious and rather lo n g hairs.
N ephrodium pubescens is one amongst a large and valuable colle ction, which had been gathered
and presented to the Horticultural S o ciety o f Jamaica by Mr. W ile s. T his colle ction, in the most
liberal maimer and with the con sen t o f Mr. W ile s, the S o c ie ty has transferred to u s ; and we are
anxious thus publicly to render onr acknowledgements for so useful and valuable a contribution to
our Herbaria.
