(017) Proposal to add a new Example after Article 11.4

Abstract

Article 11.4 of the Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018) says “For any taxon below the rank of genus, the correct name is the combination of the final epithet of the earliest legitimate name of the taxon at the same rank, with the correct name of the genus or species to which it is assigned, except …” There are many Examples in the Code under Art. 11.4, but none of them makes it clear that, for the purpose of determining the correct name of a taxon, a new combination takes priority from the date of valid publication of its basionym, provided that the new combination and its basionym have the same rank. Hence we feel that the following new Example should be included in the Code. “Ex. n. When Aeginetia acaulis (Roxb.) Walp. (in Repert. Bot. Syst. 3: 481. 1844) and A. pedunculata Wall. (in Pl. Asiat. Rar. 3: 13. 1831) are considered to apply to the same species, A. acaulis is the correct name because it is the combination of the final epithet of Orobanche acaulis Roxb. (Pl. Coromandel 3: 89. 1820), the earliest legitimate name of the taxon at specific rank, with Aeginetia L., the correct name of the genus to which the species is assigned.” We thank Dr. A.A. Mao, Director, Botanical Survey of India (BSI), and Dr. V.P. Prasad, Scientist ‘E’ and Head of the Office, Central National Herbarium, BSI, for providing facilities. We also thank N.J. Turland for improving the manuscript.
