(162) Proposal to add “first‐step typification” and “second‐step typification” to the Glossary

According to Art. 9.17 of the Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018), a second-step typification can be applied to a lecto-, neo-, or epitypification. In our experience, the terms first-step and second-step lectotypification are becoming more and more frequent in the taxonomic literature. The terms are implicitly explained in the context of Art. 9.17 and Ex. 14 but are absent from the Glossary. Because these terms are becoming more common, they should be explained in the Glossary. Accordingly, we propose the following. “first-step typification. See second-step typification.” “second-step typification. Designating a single specimen as the lectotype, neotype, or epitype for a name where a single gathering but more than one specimen was originally (in the first-step typification) designated as lectotype or neotype, or epitype (Art. 9.17 and Ex. 14).”
