6.1. Effective publication is publication in accordance with Art. 29, 30, 31
6.2. Valid publication of names is publication in accordance with Art. 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45 or H.9 (see also Art. 61).
6.3. A legitimate name is one that is in accordance with the rules.
6.4. An illegitimate name is one that is designated as such in Art. 18.3, 19.5, or 52, 53, 54 (see also Art. 21 Note 1 and Art. 24 Note 2). A name which according to this Code was illegitimate when published cannot become legitimate later unless it is conserved or sanctioned.
6.5. The correct name of a taxon with a particular circumscription, position, and rank is the legitimate name which must be adopted for it under the rules (see Art. 11).
Ex. 1. The generic name Vexillifera Ducke (1922), based on the single species V. micranthera, is legitimate because it is in accordance with the rules. The same is true of the generic name Dussia Krug & Urb. ex Taub. (1892), based on the single species D. martinicensis. Both generic names are correct when the genera are thought to be separate. Harms (in Repert. Spec. Nov. Regni Veg. 19: 291. 1924), however, united Vexillifera and Dussia in a single genus; the latter name is the correct one for the genus with this particular circumscription. The legitimate name Vexillifera may therefore be correct or incorrect according to different concepts of the taxa.
6.6. In this Code, unless otherwise indicated, the word "name" means a name that has been validly published, whether it is legitimate or illegitimate (see Art. 12).
6.7. The name of a taxon below the rank of genus, consisting of the name of a genus combined with one or two epithets, is termed a combination (see Art. 21, 23, and 24).
Ex. 2. Combinations: Mouriri subg. Pericrene, Arytera sect. Mischarytera, Gentiana lutea, Gentiana tenella var. occidentalis, Equisetum palustre var. americanum, Equisetum palustre f. fluitans.
6.8. Autonyms are such names as can be established automatically
under Art. 22.3 and 26.3,
whether or not they appear in print in the publication in which
they are created (see Art. 32.7).
