Tryon, 1964: 225). Plumier, Traite´ Foug. Ame´r., pl. 116, 1705, illustrating a collection from Martinique.

    This rather rare species is easily distinguished from similarly shaped species of Polytaenium by the scattered, superficial sporangia. Sterile fronds can be discerned by the longer creeping rhizomes and large, papyraceous blades.
