Rakotondrainibe F. 2010. — Deux espèces nouvelles de Pseudotectaria Tardieu sect.Pseudotectaria (Pteridophyta, Tectariaceae) de Madagascar et discussion sur les sectionsPseudotectaria et Isopinnatae Holttum. Adansonia, sér. 3, 32 (1): 31-38.

Two new species of Pseudotectaria Tardieu sect. Pseudotectaria (Pteridophyta, Tectariaceae) from Madagascar and discussion on the sections Pseudotectaria et Isopinnatae Holttum.

Two new species of Pseudotectaria Tardieu sect. Pseudotectaria, P. analamazaotrensis Rakotondr. and P. jouyana Rakotondr., are described and illustrated. Their affinities with the two others species in the same section, P. crinigera (C.Chr.) Tardieu and P. decaryana (C.Chr.) Tardieu, are examined and summarized in a new identification key. Pseudotectaria analamazaotrensis differs by the pinnae being simple and petiolulate, the proximal pinnae being as long as the next ones with the acroscopic side as wide as the basiscopic one. The proximal pinnae of P. jouyana are pinnatiseque; veins from the acroscopic side of pinnae anastomosing and those from basiscopic side often free. Criteria differentiating Pseudotectaria and Isopinnatae Holttum sections are updated taking into account the two new species morphology.
