40.1. In order to be validly published, names of hybrids of specific or lower rank with Latin epithets must comply with the same rules as names of non-hybrid taxa of the same rank.
Ex. 1. "Nepeta ×faassenii"
(Bergmans, Vaste Pl. Rotsheesters, ed. 2: 544. 1939, with a description in Dutch; Lawrence in Gentes Herb. 8: 64. 1949, with a diagnosis in
English) is not validly published, not being accompanied by or associated with a Latin description or
diagnosis. The name
Nepeta ×faassenii Bergmans ex Stearn (1950) is validly
published, being accompanied by a Latin description.
Ex. 2. "Rheum ×cultorum"
(Thorsrud & Reisaeter, Norske Plantenavn: 95. 1948), being there a nomen
nudum, is not validly published.
Ex. 3. "Fumaria ×salmonii"
(Druce, List Brit. Pl.: 4. 1908) is not validly published, as only the presumed parentage
F. densiflora × F. officinalis is stated.
Note 1. For names of hybrids of the rank of genus or subdivision of a genus, see Art. H.9.
