≡ Tectaria pica (L. f.) C. Chr. in Dansk Bot. Ark. 7: 65. 1932. ( Tectariaceae )

Lectotypus (designated here): MADAGASCAR: “43. Polypodium de l’Isle de Madagascar ”, s.d., Commerson s.n. ( LINN-HS nº 1622.112 image seen ; isolecto-: MPU [ MPU1061079 ]!, P-LA [ P00564805 ] image seen ; possible isolecto-: MPU [ MPU1061080 ]!).

Notes. – A single specimen of original material seen by Linnaeus f. is preserved in LINN-HS. Thouin’s handwritten label with the number “43” is completed by Linnaeus f.’s annotation “pica ny”. This collection is here designated as lectotype. Duplicates of this original material are extant in P-LA [P00564805] and MPU [MPU1061079]. A second collection in MPU is missing the number “43” but seems likely to be a duplicate of the original material and is considered here as a possible isolectotype.

Tectaria pica is endemic to Mauritius, Réunion, and Madagascar ( BADRÉ et al., 2002).
