Pteridaceae is a large family of ferns in New Zealand with six genera, 15 indigenous species and 11 naturalised species. Eleven lectotypes are designated for basionyms relevant to New Zealand – Adiantum affine var. heterophyllum Colenso, A. cunninghamii Hook., A. pullum Colenso, A. trapeziforme G.Forst., A. trigonum Labill., Cheilanthes sieberi var. deltoidea J.B.Armstr., C. kirkii J.B.Armstr., Pteris affinis A.Rich., P. macilenta A.Rich., P. macilenta var. saxatilis Carse, and P. pendula Colenso. No type material has been found for the indigenous taxon Adiantum affine var. chathamicum Field, and the type for this name remains undesignated. Lectotypes are being chosen where possible for all names at specific and subspecific rank, for which no holotype was designated by the original author, in order to fix the application of the name concerned. Justification for the choice is provided in each case. This article 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.

蕨科是新西兰的一个大蕨类科，有六个属，15个土著物种和11个归化物种。为与新西兰有关的别名（Adiantum affine var）指定了11种选型。heterophyllum科伦索，A. cunninghamii钩，A. pullum科伦索，A. trapeziforme G.Forst，A. trigonum Labill，Cheilanthes sieberi变种。deltoidea JBArmstr。，C. kirkii JBArmstr。，凤尾AFFINIS A.Rich。，P. macilenta A.Rich。，P. macilenta变种。saxatilis Carse，以及P. pendula Colenso。找不到本地分类单元铁线蕨仿射变种的类型材料。chathamicum字段，并且该名称的类型未指定。对于特定和亚特定等级的所有名称，都将尽可能选择选型，而原作者没有为其指定整型，以固定相关名称的应用。在每种情况下都提供了选择的理由。本文对澄清新西兰植物名称数据库（NgāTipu Aotearoa）和新西兰电子植物区系的分类学和命名地位做出了贡献。
