VALID PUBLICATION OF NAMES
NAMES OF NEW TAXA
39.1. 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).
Ex. 1. Arabis “Sekt. Brassicoturritis O. E. Schulz” and A. “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.
Ex. 2. “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.
Ex. 3. 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).
39.2. 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).
39A.1. Authors publishing names of new taxa should give or cite a full description in Latin or English in addition to the diagnosis.
