Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

We present a taxonomic treatment for the species of Didymochlaenaceae and Dryopteridaceae occurring in the region of Viçosa, Minas Gerais, Brazil. This study was based on 50 herbarium gatherings from IAN, K, NY, PACA, RB, SP, UPCB, US, and VIC. Didymochlaenaceae is represented by a single species, Didymochlaena truncatula, whereas Dryopteridaceae has 11 infrageneric taxa in seven genera: Ctenitis (four taxa, including two varieties), Megalastrum (two species), Mickelia, Parapolystichum, Polybotrya, Rumohra, and Stigmatopteris (one species each). Among the 12 infrageneric taxa here recognized, seven are endemic to the Brazilian Atlantic Forest. Ctenitis distans var. isabellina, Megalastrum connexum, and Polybotrya speciosa are here reported for the first time in Viçosa. Identification keys, descriptions, illustrations, geographical distribution, and comments are presented to all taxa.
