SECTION 2. CONDITIONS AND DATES OF VALID
PUBLICATION OF NAMES
Article 40
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.
