Doubtful species

1. Lindsaea decrescens Copel. “As stated by Copeland, this is intermediate between L. repens (‘L. macraena, L. longa’) and L. fissa. The isotype in MICH from Copeland’s herbarium is rather scrappy. I doubt whether it represents a distinct species” –Kramer, Fl. Males. Ser. ii 1 (1971) 253.
2. Lindsaea longa Copel. Probably only an usually deeply incised form of L. repens (Bory) Thwaites var. sessilis (Copel.) Kramer.
