CHAPTER V. Valid publication of names
SECTION 2. Names of new taxa
Article 39
- In order to be validly published, a name of a new taxon (algae and fossils excepted) published between 1 January 1935 and 31 December 2011, inclusive, must be accompanied by a Latin description or diagnosis or by a reference (see Art. 38.13) to a previously and effectively published Latin description or diagnosis (but see Art. H.9; for fossils see Art. 43.1; for algae see Art. 44.1).
- Arabis “Sekt. Brassicoturritis O. E. Schulz” and “Sekt. Brassicarabis O. E. Schulz” (in Engler & Prantl, Nat. Pflanzenfam., ed. 2, 17b: 543–544. 1936), published with German but no Latin descriptions or diagnoses, are not validly published names.
- “Schiedea gregoriana” (Degener, Fl. Hawaiiensis, fam. 119. 9 Apr 1936) was accompanied by an English but no Latin description and is not therefore a validly published name. Schiedea kealiae Caum & Hosaka (in Occas. Pap. Bernice Pauahi Bishop Mus. 11(23): 3. 10 Apr 1936), the type of which is part of the material used by Degener, is provided with a Latin description and is validly published.
- Alyssum flahaultianum Emb., first published without a Latin description or diagnosis (in Bull. Soc. Hist. Nat. Maroc 15: 199. 1936), was validly published posthumously when a Latin translation of Emberger’s original French description was provided (in Willdenowia 15: 62–63. 1985).
- “Malvidae” was not validly published by Wu (in Acta Phytotax. Sin. 40: 308. 2002) by reference to “Malvaceae” (Adanson, Fam. Pl. 2: 390. 1763) because the latter was associated with a description in French, not a description or diagnosis in Latin as required by Art. 39.1. Malvidae was later validly published by Thorne & Reveal (in Bot. Rev. 73: 111. 2007).
- In order to be validly published, a name of a new taxon published on or after 1 January 2012 must be accompanied by a Latin or English description or diagnosis or by a reference (see Art. 38.13) to a previously and effectively published Latin or English description or diagnosis (for fossils see also Art. 43.1).
