The hybrid between Tectaria fimbriata and T . coriandrifolia is T . × amesiana A. A. Eaton. Although intermediate between the two parents, the hybrid will lead to T . fimbriata in the key. The hybrid may be distinguished from T . fimbriata by scattered hairs on abaxial surface of petioles and misshapen spores.
