Sori numerous, subaxillary, stalked or sessile, directed downward at an angle from plane of blade; involucres tubular or narrowly funnelform, marginate or winged on the sides, slightly bilobed at apex.

Discussion:

Type. Swartz, from Jamaica without exact locality (S, photo U S ; probable isotype SBT).

Syn. Trichomanes scandens of Hedwig, Fil. gen. sp., t. 6. 1799, not Linnaeus, 1753. (Swartz cited Hedwig's plate of'T. scandens" as illustrating his new species T. radicans.)
