This form looks very different from the type, but it can not be distinguished 
even as variety; in some specimens are to be found young leaves, which are fully 
identical with the typical form. With this large form agree the Porto Rico and 
Jamaican original specimens of A. dissidens Mett. (Syn. A. Sintenisii Kuhn) and N. 
jamaicense Bak. The latter differs from the Cuban form only by its lighter scales 
of the rhizome, more distinctly stalked pinne, which are often unequal, at the 
base, and by less stellato-pilose leaf-tissue and somewhat sided thinner texture. A. 
dissidens is almost quite identical with jamaicense. I have not seen the original 
specimen of it, which was collected in Porto Rico by Batsis, but a sketch of it is 
found in Herb. Berol, which is from the hand of METTENIUS and perfectly agrees 
with the original diagnosis. It is absolutely identical with A. Sintenisii from the 
same island. In this form the veins frequently are united in the lobes, so that 
they form costular areoles; BAKER, therefore, placed it in the subgenus Pleocnemia. 
The sori are perhaps closer to the margin than in the other forms of the species.

Type from Jamaica, leg. Swanrz (S), 
I think that this species is distinct from JD. reptans, although it is difficult to 
give good characters by which it can be distinguished from not-rooting forms of 
that species. The main characters are: Leaf pinnate to short of the never rooting 
apex, often long tapering almost from the base, 3—5 dem long, chartaceous or 
firmly membranous, fresh-green, often glossy, rachis more or less pubescent by as 
well long, simple hairs as minute stellate ones. Pinnz very numerous; often 25 
to a side, most of them distinctly stalked, often characteristically falcate, the base 
generally cordate, the point obtuse or acute, 4—6 cm long, */1—1'/2 cm broad, the 
margins subentire, crenate, or, often more or less lobed into rounded, somewhat 
oblique lobes, often auricled on both sides of the base, ciliate, upperside glabrous, 
costzte and veins beneath hairy by long, simple hairs and small, stellate hairs, leaf- 
tissue glabrous. Lower pinnz not or only slightly reduced. Veins simple, 3-4 
jugate, prominent beneath, the basal pair always anastomosing. Sori near the 
midvein of the lobe, furnished with a small indusium, which is ciliated by simple
