Taxonomic notes on the New Zealand flora: lectotypes in the fern families Dennstaedtiaceae and Lindsaeaceae.

Dennstaedtiaceae is a medium-sized family of ferns in New Zealand with 11 indigenous and two naturalised species. Lindsaeaceae is a small family with just three native species and one naturalised. Three lectotypes are chosen for basionyms relevant to New Zealand:Dicksonia davallioidesR.Br.,Lindsaea trilobataColenso andPteris vespertilionisLabill. Justification for the choice is provided in each case. 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.
