Inadvertent lectotypifications of Australian Dillenia and Tetracera (Dilleniaceae)

Abstract

Dillenia L. and Tetracera L. (Dilleniaceae) were revised by R. D. Hoogland in 1952 and 1953 respectively. The Australian species Dillenia alata (R.Br. ex DC.) Banks ex Martelli and Tetracera daemeliana F.Muell. were treated in these revisions (Hoogland 1952, 1953), where they were inadvertently lectotypified by Hoogland indicating the “holotype” for each name (see McNeill 2014). Hoogland’s use of the term “holotype” is to be corrected to “lectotype” according to Art. 9.10 of the International Code of Nomenclature for algae, fungi, and plants (hereafter ICN; Turland et al. 2018). This correction is possible as before 2001 it was not necessary to use the phrase “here designated” or an equivalent when lectotypifying names (ICN Art. 7.11). Because multiple sheets exist at the designated herbaria, there may be some confusion as to which specimen is the lectotype. In this paper I clarify typification of these names, preparatory to a treatment of Australian Dilleniaceae for the Flora of Australia. Digital images of all type specimens were viewed on the JSTOR Global Plants website (https://plants.jstor.org).
