SECTION 3. AUTHOR CITATIONS
50.1. When a taxon at the rank of species or below is transferred from the non-hybrid category to the hybrid category of the same rank
(Art. H.10.2), or vice versa, the author citation remains unchanged but may be followed by an indication in parentheses of the original category.
Ex. 1. Stachys ambigua Sm. (1809) was published as the name of a species. If regarded as applying to a hybrid, it may be cited as
Stachys ×ambigua Sm. (pro sp.).
Ex. 2. The binary name Salix ×glaucops Andersson (1868) was published as the name of a hybrid. Later, Rydberg (in Bull. New York Bot. Gard. 1: 270. 1899) considered the taxon to be a species. If this view is accepted, the name may be cited as Salix glaucops Andersson (pro hybr.).
