(081–082) Proposals to allow the use of a hyphen to be treated as a correctable error in all nothogeneric names that are condensed formulas

In the current Shenzhen Code (Turland & al. in Regnum Veg. 159. 2018), one might infer from last sentence of Art. H.6.2, which covers nothogeneric names bigeneric hybrids that are condensed formulas (“The use a hyphen instead or addition to connecting vowel is treated as an error be corrected by deletion hyphen.”), this rule applies only hybrids. When sentence, was new Code, originally proposed Greuter (in Taxon 65: 419. 2016), its relevance other not apparently appreciated. Indeed, Ex. 5 under H.6.2 presents two both involve hybrids, published with hyphen, accepted and used without hyphen: ×Anthematricaria ×Brassocattleya, having been ‘Anthe-Matricaria’ ‘Brasso-Cattleya’, respectively. The placement hyphenation suggests it does cover all situations for formulas. particular, trigeneric covered H.6.4, parallel provision permit hyphens more currently exist. Yet first case cited 7 Article such nothogenus, ×Sophrolaeliocattleya Hurst J. Roy. Hort.

As such, formula not, H.6.4 requires, “combined into single word”, owing intercalated hyphens, so name cannot validly (Art. 32.1(c)). Another related example ×Brassolaeliacattleya J.G. Fowler Gard.
