Engel, John J.; Smith Merrill, Gary L.
This paper presents an overview of the infrageneric classification to be used in the treatment of Plagiochila in the New Zealand Liverwort Flora. Included are re-evaluations of all names and concepts in current use, and synonymy. Plagiochila sect. Cucullatae Schiffn. (subg. Metaplagiochila Inoue) is recognized for the first time from New Zealand. Plagiochila sect. Tayloriae Carl. has been misapplied, and is an older name for sect. Ramosissimae H. Inoue & Schust. The following new sections are described: Plagiochila sect. Mittenia J.J. Engel & G.L. Merr., sect. nov.; Plagiochila sect. Hodgsonia J.J. Engel & G.L. Merr., sect. nov.; Plagiochila sect. Colensoa J.J. Engel & G.L. Merr., sect. nov.; and Plagiochila sect. Caducifoliae J.J. Engel & G.L. Merr., sect. nov. These novelties are published separately to make them immediately available for use.
