This form looks very different from the type, hut it can not he distlnguislied 

 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 pinnæ, 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 Balbis, 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 

 thej' form costular aréoles; Baker, therefore, placed it in the subgenus Pleocnemia. 

 The sori are perhaps closer to the margin than in the other forms of the species.

I think that this species is distinct from D. 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. Pinnæ 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, 'Va—Vh 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, 

 costæ and veins beneath hairy by long, simple hairs and small, stellate hairs, leaf- 

 tissue glabrous. Lower pinnæ 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
