POLYPODIUM (Crasprparia) prnosELorpas, L. 
Small tongue-shaped Polypody. 
PotyPoprum (Craspedaria) piloselloides ; caudex long-creeping, filiform, scarcely 
thicker than a sparrow’s quill, setaceo-paleaceous; fronds scattered, distant, 
of two kinds, stipitate, coriaceo-carnose, costate, obtuse, minutely subu- 
lato-paleaceous; stipes one to one and a half inch long, setaceo-palea- 
ceous ; sterile fronds two to two and a half inches long, oblong or ovato- 
oblong ; fertile ones lanceolate, two and a half to three inches long; veins 
anastomosing, with large, oblique, hexagonal, oblong areoles next the costa, 
with a free vein soriferous at the apex, marginal areoles smaller; sori large, 
in two rows, one on each side nearer the costa than the margin, large, pro- 
minent; capsules long, stipitate, mixed with long, hastate, stipitate scales, 
longer than the capsules.

on dry rocks in mountain districts frequent. West Indian Islands generally.

This belongs to a small group of Polypodium, which has been 
distinguished as a genus by Link, under the name of Craspe- 
daria, chiefly by its habit and dimorphous fronds; but he in- 
cluded some species of Mphobolus. M. Fée adopts the genus, 
excluding the Mphoboli, mainly however on account of the diffe- 
rent venation. The present species is extremely common in 
perhaps all the West Indian Islands ; less abundant, it would 
appear, on the continent of South America. The exact limits of 
the species are not accurately defined. It borders very closely on 
the one hand to the Polyp. aurisetum, Raddi, Fil. Brasil., p. 12. 
t. 23. f. 1 (which indeed is the P. piloselloides of that author’s 
Synopsis, p. 46); and on the other to the P. Cayennense, Desv. 
(Pol. ciliatum, Willd., Craspedaria, Zink), from which it chiefly 
differs in the very narrow fertile fronds; so narrow that the
