Abstract

Recent research has necessitated a review of the nomenclature of the genus Ophioglossum in Africa. This paper establishes a new species, O. caroticaule J. E. Burrows, a new subspecies, O. vulgatum L. subsp. africanum Pocock ex J. E. Burrows, and a change in status, O. latifolium (Prantl) J.E. Burrows (basionym: O. gomezianum var.  latifolium Prantl). Lectotypification is provided for O. gracillimum Welw. ex Hook. & Bak., O. lusoafricanum Welw. ex Prantl, O. latifolium (Prantl) J.E. Burrows, and 0. rubellum Welw. ex A. Braun. Nomenclatural problems in O. lancifolium Presl are discussed.
