A taxonomic revision of the genus <i>Grammitis</i> Sw. (Grammitidaceae : Filicales) in New Zealand

Abstract

Abstract Four of the 10 taxa of Grammitis recorded from New Zealand and its subantarctic islands are new: G. givenii, G. magellanica subsp. nothofageti, G. pseudociliata , and G. rawlingsii all belong to the group of G. billardieri Willd., which is here treated in a strict sense. G. magellanica and G. patagonica are recorded for the first time in New Zealand. G. armstrongii is reinterpreted to include extra‐Australasian material. Synonymy, typification, description, habitat data, extra‐New Zealand distribution, citation of specimens examined, and distribution maps are given for each species and a key is provided.
