  • Discussion

    Polypodium lycopodioides L., Sp. Pl. 2: 1082. 1753. Lectotype (chosen by Proctor, 1977: 338). LINN 1251.2, locality unknown (see also Jackson, 1912).

    Unverified, Doubtful, or Mistaken Reports. Tab (reported by Smith, 1981, and Magan˜a, 1992, but not verified). Microgramma lycopodioides is distinct by its glabrous blades and slender rhizomes with concolorous scales. Reports of this species from Africa, Madagascar, and Mauritius pertain to the closely related, but specifically different, M. mauritiana (Willd.) Tardieu [synonym: M. owariensis (Desv.) Alston].
