Crepidomanes parvulum (Poir.) Nivart, Senterre & Dubuisson , comb. nov.

Trichomanes parvulum Poir. ( Poiret 1808: 64) , non Copel. ( Copeland 1933: 145), type citation: M. du Petit-Thouars à l’île de Madagascar. Type:— MAURITIUS?. Without locality, without date, L.-M.A. du Petit-Thouars s.n. (lectotype P, P00065014!, here designated excl. specim. P01190780!; isolectotype P, P00065015!, excl. specim. P01190781!). Note.—The specimens were first considered to be from Madagascar as indicated by Poiret himself, but as highlighted by Tardieu-Blot (1941), the Petit-Thouars’ material studied by Poiret would actually have been collected in ‘Ile de France’ (Mauritius), hence the present suggested locality.
