The nomenclatural history of theAsplenium obtusatumcomplex is reviewed. It is shown that when treated at subspecific rank,A. obtusatumsubsp. northlandicumBrownsey, based on a New Zealand type, is the correct name for the octoploid taxon that occurs in both New Zealand and Australia. However, when raised to species rank there are two earlier validly published names,A. decurrensWilld. andA. sarmentosumWilld., based on Australian types, that take priority overAsplenium northlandicum(Brownsey) Ogle. Both names relate to the same taxon and were published simultaneously. The nameA. decurrensis preferred because the holotype is based on a herbarium specimen, whereas the type ofA. sarmentosumis an illustration. This short communication is a contribution towards clarifying the taxonomic and nomenclatural status of New Zealand plants for the plant names database (Ngā Tipu Aotearoa) and the electronic Flora of New Zealand.
