Ferns of Viçosa, Minas Gerais State, Brazil: Polypodiaceae (Polypodiales, Filicopsida, Tracheophyta)

ABSTRACT As part of an ongoing project treating the ferns and lycophytes from the region of Viçosa, MG, Brazil, we here present the taxonomic treatment of Polypodiaceae. We performed field expeditions in remaining forest patches and disturbed sites from 2012 to 2016. We also revised the Polypodiaceae collection of VIC herbarium. In the region of Viçosa, 19 species of Polypodiaceae occur: Campyloneurum centrobrasilianum, C. decurrens, C. lapathifolium, C. phyllitidis, Cochlidium punctatum, Microgramma crispata, M. percussa, M. squamulosa, M. vacciniifolia, Niphidium crassifolium, Pecluma filicula, P. plumula, P. truncorum, Phlebodium areolatum, P. decumanum, Pleopeltis astrolepis, P. minima, Serpocaulon fraxinifolium, and S. menisciifolium. Among them, six are endemic to the Atlantic Forest. During our search in VIC, we found an isotype of Campyloneurum centrobrasilianum. We present keys, descriptions, illustrations, examined materials, and comments of all taxa.
