(196–197) Proposals regarding unpublished materials (amendments to Article 6.1 and the footnote of Article 6.13)

The Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018) amended Art. 6.1 by adding the following sentence: “Except specified cases (Art. 8.1, 9.4(a), 9.22, Rec. 9A.3, and 40.7), text illustrations must be effectively published to taken into account for purposes of this Code.” Synopsis Proposals Congress was prescient when it noted under proposal 6 Prop. A) that resulted addition “there remains worry other unwanted consequences might exist” Wiersema Taxon 66: 221. 2017). Indeed, these worries are more than hypothetical: (1) language fails carve out an exception unpublished illustration as epitype because 9.9 is not 6.1. While there Article mentions only holotype, lectotype neotype. (2) Various have been conserved types 14.9. Because 6.1, clear permitted. (3) 46.9 provides “external evidence” can used attribute authorship some cases. Recommendation 9A.1 9B.1 require “understanding” author's practices “critical knowledge”. Presumably, no longer purposes. Attempting set forth all exceptions would exhaustive review every provision Code, consideration whether each way implicated new rule Future amendments may well additional changes, overlooked. For example, a recent amend so-called usage test 9.1(b) consider “evidence protologue or elsewhere” establish original author name one element 69: 626–627. 2020). Due evidence limited text. “6.1. Effective publication accordance with 29–31. Except 8.1 any reference type 9.9, 9.19, 9A.1, 9B.1, 10.4, 40.7, 46.9) where use explicitly implicitly permitted, illustrations1 To avoid possible confusion over status text, definition 6.13 footnote) should clarified include them. These materials useful determining superseded 9.19(c). “1 Protologue (from Greek πρώτος, protos, first; λόγος, logos, discourse): everything associated at part its valid publication, e.g. description, diagnosis, illustrations, references, synonymy, geographical data, citation specimens, discussion, comments. It also includes published, cited, referenced (including illustrations).” I thank Nicholas J. Turland John H. their comments suggestions, which improved proposals.
