A revised classification of New Zealand pteridophytes with a synonymic checklist of species

Abstract

A revised classification and checklist of New Zealand pteridophytes is presented, based on recently published phyletic schemes for the Pteridophyta, and on revisions of individual families and genera. The list comprises 211 species of which 22 are adventive and 189 native; the latter include 8 unnamed species (either undescribed or unidentified) and a further 6 which are subdivided into separate subspecies. Ofthe native taxa, 89 species (47%) and 3 subspecies (50%) are believed to be endemic to the New Zealand botanical region. Individual taxa are discussed with particular reference to recent revisions and areas requiring further study. Synonymic and alphabetical lists are provided of all validly published pteridophyte names based on New Zealand types or used by authors with reference to the New Zealand flora. The more important species erroneously or dubiously recorded for New Zealand are also listed.
