CHAPTER IV. EFFECTIVE AND VALID PUBLICATION

SECTION 2. CONDITIONS AND DATES OF VALID PUBLICATION OF NAMES

Article 36

36.1. On or after 1 January 1935 a name of a new taxon (algal and all fossil taxa excepted) must, in order to be validly published, be accompanied by a Latin description or diagnosis or by a reference to a previously and effectively published Latin description or diagnosis (but see Art. H.9).

Ex. 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.

Ex. 2. "Schiedea gregoriana" (Degener, Fl. Hawaiiensis, fam. 119. 9 Apr 1936) was accompanied by an English but no Latin description and is accordingly not a validly published name. S. 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).

36.2. In order to be validly published, a name of a new taxon of non-fossil algae published on or after 1 January 1958 must be accompanied by a Latin description or diagnosis or by a reference to a previously and effectively published Latin description or diagnosis.

Ex. 4. Although Neoptilota Kylin (Gatt. Rhodophyc.: 392. 1956) was accompanied by only a German description, it is a validly published name since it applies to an alga and was published before 1958.

36.3. In order to be validly published, a name of a new taxon of fossil plants published on or after 1 January 1996 must be accompanied by a Latin or English description or diagnosis or by a reference to a previously and effectively published Latin or English description or diagnosis.

Recommendation 36A

36A.1. Authors publishing names of new taxa of non-fossil plants should give or cite a full description in Latin in addition to the diagnosis.
