Typification of names of South American taxa related to Woodsia montevidensis (Woodsiaceae)

Abstract

A revision of the nomenclature of six South American taxa related to Woodsia is presented, as a part of a taxonomic revision of the genus in South America. Lectotypes are selected for Cheilanthes crenata, Woodsia crenata var. pallidipes, Woodsia incisa, Woodsia montevidensis var. fuscipes and the second step lectotypification for Dicksonia montevidensis and Woodsia peruviana, based on the analysis of their protologues and original herbarium material. All names are currently synonyms of Woodsia montevidensis. Physematium incisum (Gillies ex Hook. & Grev.) Kunze constitutes an illegitimate name and Physematium cumingianum is considered as nomen inquirendum.
