“…Because of the complex taxonomy of Blechnaceae, carrying out rigorous systematic reviews at all levels of classification is needed. Work is important below the genus level, as in recent decades some taxa have been resurrected, and some originally described varieties that had fallen into disuse, have now been elevated to the species category (Brown & Brown 1931;Lange & Parris 2019). Moreover, new species, new sections (Chambers & Farrant 1993;Rojas 2005Rojas , 2008Rakotondrainibe et al 2013), and new interspecific hybrids (Aguiar et al 2007;Dittrich et al 2015) have been described.…”

Cranfillia opaca is a fern species present in New Caledonia, for which a great variation in morphology is reported. Some other species such as Blechnum deplanchei have been proposed, but those were later synonymized with C. opaca. In this work, we have studied this taxon at both the morphological and the anatomical level, as well as its ecology and geographical distribution. We found differences between C. opaca s.s. and B. deplanchei in the morphology of the sterile and fertile fronds, in several morphoanatomical features such as trichome shape, length, and distribution, and length and/or shape of different structures of sporangia and spores. The distribution of both taxa was also different, but they are sympatric at some localities. The differences identified in this study support the recognition of both taxa, and the combination of Cranfillia deplanchei (Baker) Vázquez Ferreira & Gabriel y Galán, which we propose here. A new taxonomic description is provided for both species.

“…The genus Cranfillia Gasper & V.A.O. Dittrich currently includes 22 species, recognized by different authors (Gasper et al 2016;Chambers & Wilson 2019;Lange & Parris 2019;Bauret et al 2020), being the fourth largest genus in the family after Parablechnum C. Presl., Austroblechnum Gasper & V.A.O.…”
