Révision du genre Deparia Hook. & Grev. (Pteridophyta, Athyriaceae) à Madagascar: trois espèces nouvelles, une synonymie nouvelle et des hybrides présumés

Rakotondrainibe, F. & A. Jouy (2016). Revision of the genus Deparia Hook. & Grev. (Pteridophyta, Athyriaceae) from Madagascar: three new species, a new synonymy and putative hybrids. Candollea 71: 357–371. In French, French and English abstracts. The first two revisions of the genus Deparia Hook. & Grev. for Madagascar (Dryopteris Adans. sensu Christensen in 1932 and Cornopteris Nakai sensu Tardieu-Blot in 1958) were based on a limited number of specimens. Errors of identification of collections at the level of genus (between Deparia and Diplazium Sw.) and species were numerous. In the process of updating the pteridophyte flora of Madagascar, a new revision of the Malagasy species of Deparia is presented. Six species are recognized, five of which are endemic and one, Deparia boryana (Willd.) M. Kato, is paleotropical. Three species, Deparia florensiae Rakotondr., Deparia longipilosa Rakotondr., and Deparia septentrionalis Rakotondr., are newly described. Deparia forsythii majoris (C. Chr.) M. Kato is placed in synonymy under Deparia parvisora (C. Chr.) M. Kato and putative hybrids are detected. An identification key to the Malagasy species of Deparia is provided, along with illustrations and complete descriptions for each of the species.
