Blechnaceae is a medium-sized family of ferns in New Zealand with one genus, 23 indigenous species, two naturalised species and two nothospecies. A new combination, Blechnum × digenum (Parris) Brownsey & Perrie, is made for the hybrid between Blechnum molle (Parris) Christenh. and B. parrisiae Christenh. 11 lectotypes are chosen for basionyms relevant to New Zealand – Lomaria dura T. Moore, L. filiformis A. Cunn., L. membranacea Colenso ex Hook., L. nigra Colenso, L. oligoneuron Colenso, L. parvifolia Colenso, L. paucijuga Colenso, L. pumila Raoul, L. rotundifolia Colenso, Parablechnum procerum var. acuminatum C. Presl, and Stegania procera var. stipulosa A. Rich. No type material has been found for Blechnum capense var. auriculatum Domin, B. capense var. contractum Domin, B. capense var. hookerianum Domin, Lomaria paleacea Potts, or Lomaria pygmaea Colenso, and the types for these names remain 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（Blechnaceae）是新西兰的中型蕨类科，有一个属，23个土著物种，两个归化物种和两个异种。Blechnum  ×  digenum（Parris）Brownsey＆Perrie的新组合是为Blechnum molle（Parris）Christenh之间的杂种制成的。和B. parrisiae Christenh。选择11种与新西兰相关的词型-Lomaria dura T. Moore，L. filiformis A. Cunn。，L. membranacea Colenso ex Hook。，L. nigra Colenso，L. oligoneuron Colenso，L. parvifolia Colenso，L .。paucijuga Colenso，L. pumilaRaoul，L. rotundifolia Colenso，互花木变种 尖锐湿疣C. Presl的，和Stegania的Procera变种。stipulosa A.丰富。找不到Blechnum capense var的类型材料。首乌DOMIN，B.薄盖变种。Contractum Domin，B. capense var。虎头DOMIN，Lomaria paleacea波茨，或Lomaria矮Colenso，并且这些名称的类型仍未指定。对于可能的特定和亚特定等级的所有名称，都将选择其原型，而原作者没有为其指定任何原型，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。
