Discussion

Tectaria coriandrifolia is known in North America only from southernmost Florida; it has not been seen there for several years and is perhaps extirpated. It hybridizes with Tectaria fimbriata to form T. × amesiana A. A. Eaton [Aspidium trifoliatum (Linnaeus) Swartz var. amesianum (A. A. Eaton) Clute], which may be distinguished by its misshapen spores, fewer pinnae pairs, and dense row of hairs on the adaxial surface of the petioles. The hybrid is known only from Florida.
