Discusión taxonómica
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].A
