Neste trabalho são apresentados os dados referentes ao levantamento florístico das
famílias Grammitidaceae e Polypodiaceae, no Parque Estadual das Fontes do Ipiranga …

Recent phylogenetic analyses of grammitid ferns (Polypodiaceae) have demonstrated that
some genera recognized within this clade are not monophyletic. We focus on resolving the …

Moranopteris, a new genus of grammitid ferns here described, is segregated from
Micropolypodium on the basis of molecular phylogenetic analyses (plastid sequences …

Alansmia, a new genus of grammitid ferns is described and combinations are made for the
26 species known to belong to it. Alansmia is supported by five morphological …

We provide a synopsis to the family Polypodiaceae in Bolivia, comprising 23 genera and
209 species, which renders this the most species-rich fern family in the country. Two large …

This paper describes Ascogrammitis, a new genus of grammitid ferns formerly combined
under Terpsichore. Seventeen species are recognized, including five new ones: A …

Terpsichore, a Neotropical genus of about 70 species, was shown in previous molecular
phylogenetic studies to be polyphyletic. The present study assesses this conclusion using …

Calea× crassa, a new nothospecies is described and illustrated. The thickened pale
olivaceous leaf margins along with the mucronate teeth are unique morphological features …

A floristic survey of the Polypodiaceae in the Parque Estadual do Itacolomi is presented.
This park is located in the southern limit of the Espinhaço Range, between the municipalities …

Grammitid ferns are a well-supported clade of~ 900 primarily tropical epiphytic species.
Recent phylogenetic studies have found support for a distinctive, geographically diverse …
