A new species and a new combination in Ctenitis (Dryopteridaceae) from South America

  author={Raquel Stauffer Viveros and Alexandre Salino},
We describe a new species and propose a new combination of Ctenitis from South America. The new species is from Peru. We named it Ctenitis megalastriformis due to the resemblance to Megalastrum. The new combination corresponds to the species known until now as C. pedicellata. This species should be called C. nervata, based on the older name Aspidium nervatum. Lectotypes are designated for A. pedicellatum and Dryopteris indecora, both considered here to be synonyms of C. nervata.

Two new species of Ctenitis (Dryopteridaceae) from South America and taxonomic notes on similar species
Two new species of Ctenitis (Dryopteridaceae) from South America are described and illustrated and seven lectotypifications and two new synonyms are proposed.
Studies in the fern genera allied to Tectaria Cav. IV. The genus Ctenitis in Asia, Malesia and the Western Pacific
Seventeen new species are described, one new name proposed and four new combinations made in the genus Ctenitis of Asia, Malesia and the Western Pacific, with a new division of the species into two subgroups of informal status.
The fern-genera Tectaria, Heterogonium and Ctenitis in the Mascarene Islands
A study of many recent collections in comparison with the more fragmentary older ones, resulting in revisions of specific concepts and of synonymy, describes new species and combinations of Ctenitis lorencei and C. canacae and new varieties.
Megalastrum (Dryopteridaceae) in Brazil, Paraguay, and Uruguay
Abstract We provide keys, descriptions, illustrations, full synonymies, maps, and a list of specimens examined for species of Megalastrum found in Brazil, Paraguay, and Uruguay. Eighteen species are
A classification for extant ferns
We present a revised classification for extant ferns, with emphasis on ordinal and familial ranks, and a synopsis of included genera. Our classification reflects recently published phylogenetic
New Combinations in Megalastrum (Dryopteridaceae)
One of Carl Christensen's many important contributions to fern taxonomy was demonstrating that Dryopteris was a vast, unrelated assemblage of ferns, which was recently established as the genus Triplophylium by Holttum (1986a), and it is agreed that Megalastrum deserves generic status.
New Records of Pteridophytes from Bolivia
It is suggested that Bolivia rivals other Andean floras in richness and permit more accurate taxonomic and phytogeographic comparisons with fern floras from adjacent areas.
