CHAPTER IV. EFFECTIVE AND VALID PUBLICATION

SECTION 1. CONDITIONS AND DATES OF EFFECTIVE PUBLICATION

Article 30

30.1. Publication by indelible autograph before 1 January 1953 is effective.

Ex. 1. Salvia oxyodon Webb & Heldr. was effectively published in a printed autograph catalogue placed on sale (Webb & Heldreich, Catalogus plantarum hispanicarum ... ab A. Blanco lectarum, Paris, Jul 1850, folio).

30.2. For the purpose of this Article, indelible autograph is handwritten material reproduced by some mechanical or graphic process (such as lithography, offset, or metallic etching).

Ex. 2. H. Léveillé, Flore du Kouy Tchéou (1914-1915), is a work lithographed from a handwritten text.

30.3. Publication on or after 1 January 1953 in trade catalogues or non-scienti-fic newspapers, and on or after 1 January 1973 in seed-exchange lists, does not constitute effective publication.

30.4. The distribution on or after 1 January 1953 of printed matter accompanying exsiccata does not constitute effective publication.

Note 1. If the printed matter is also distributed independently of the exsiccata, it is effect-ively published.

Ex. 3. Works such as Lundell & Nannfeldt, Fungi exsiccati suecici ..., Uppsala 1-..., 1934-..., distributed independently of the exsiccata, whether published before or after 1 January 1953, are effectively published.

Recommendation 30A

30A.1. It is strongly recommended that authors avoid publishing new names and descriptions or diagnoses of new taxa in ephemeral printed matter of any kind, in particular that which is multiplied in restricted and uncertain numbers, where the permanence of the text may be limited, where the effective publication in terms of number of copies is not obvious, or where the printed matter is unlikely to reach the general public. Authors should also avoid publishing new names and descriptions or diagnoses in popular periodicals, in abstracting journals, or on correction slips.
