Studies of Fissidens (Bryophyta: Musci): New taxa and new records for New Zealand

Abstract

Two new taxa in the moss genus Fissidens are described from aquatic habitats in New Zealand: F. waiensis sp. nov. and F. rigidulus Hook.f. & Wilson var. pseudostrictus var. nov. Fissidens perangustus Broth., a species known previously only from Australia, is recognised in New Zealand, and a lectotype designated. The presence of F. bryoides Hedw. in New Zealand is confirmed, based on modern collections. Fissidens vario-limbatus Allison and F. leptocladus Müll.Hal. ex Rodway var. cheesemanii Dixon are placed in the synonymy of F. leptocladus var. leptocladus; F. australiensis A.Jaeger is reduced to a variety of F. tenellus Hook.f. & Wils.; and the new combination F. tenellus var. leptochaete (Dusén) J.E.Beever & I.G.
