Matched Legal Cases: ['Art. 18', 'Art. 1', 'Art. 14', 'Art. 32', 'Art. 53', 'Art. 11', 'Art. 53', 'Art. 52']

11.1. Each family or taxon of lower rank with a particular circumscription, position, and rank can bear only one correct name, special exceptions being made for 9 families and 1 subfamily for which alternative names are permitted (see Art. 18.5 and 19.7). However, the use of separate names for the form-taxa of fungi and for morphotaxa of fossil plants is allowed under Art. 1.3, 59.4, and 59.5.
11.4. For any taxon below the rank of genus, the correct name is the combination of the final epithet of the earliest legitimate name of the taxon in the same rank, with the correct name of the genus or species to which it is assigned, except (a) in cases of limitation of priority under Art. 14, 15, 56, or 57, or (b) if the resulting combination could not be validly published under Art. 32.1(c) or would be illegitimate under Art. 53, or (c) if Art. 11.7, 22.1, 26.1, or 59 rules that a different combination is to be used.
Ex. 9.The correct name for Rubus aculeatiflorus var. taitoensis (Hayata) T. S. Liu & T. Y. Yang (in Annual Taiwan Prov. Mus. 12: 12. 1969) is R. taitoensis Hayata var. taitoensis, because R. taitoensis Hayata (1911) has priority over R. aculeatiflorus Hayata (1915).
Ex. 10. When transferring Spartium biflorum Desf. (1798) to Cytisus Desf., Spach correctly proposed the substitute name C. fontanesii Spach (1849) because of the previously and validly published C. biflorus L'Hér. (1791); the combination C. biflorus based on S. biflorum would be illegitimate under Art. 53.1.
Ex. 13. Cucubalus behen L. (1753) when transferred to Behen Moench was legitimately renamed B. vulgaris Moench (1794) to avoid the tautonym "B. behen". In Silene L., the epithet behen is unavailable because of the existence of S. behen L. (1753). Therefore, the substitute name S. cucubalus Wibel (1799) was proposed. This, however, is illegitimate (Art. 52.1) since the specific epithet vulgaris was available. In Silene, the correct name of the species is S. vulgaris (Moench) Garcke (1869).
Ex. 15.The final epithet of the combination Thymus praecox subsp. arcticus (Durand) Jalas (in Veröff. Geobot. Inst. ETH Stiftung Rübel Zürich 43: 190. 1970), based on T. serpyllum var. arcticus Durand (Pl. Kaneanae Groenl. 196. 1856), was first used at the rank of subspecies in the combination T. serpyllum L. subsp. arcticus (Durand) Hyl. (in Uppsala Univ. Årsskr. 1945(7): 276. 1945). However, if T. britannicus Ronniger (1924) is included in this taxon, the correct name at subspecies rank is T. praecox subsp. britannicus (Ronniger) Holub (in Preslia 45: 359. 1973), for which the final epithet was first used at this rank in the combination T. serpyllum subsp. britannicus (Ronniger) P. Fourn. (Quatre Fl. France: 841. 1938, "S.-E. [Sous-Espèce] Th. Britannicus").
Ex. 16. Tausch included two species in his new genus Alkanna: A. tinctoria Tausch (1824), a new species based on "Anchusa tinctoria" in the sense of Linnaeus (1762), and A. mathioli Tausch (1824), a nomen novum based on Lithospermum tinctorium L. (1753). Both names are legitimate and take priority from 1824.
Ex. 24. By describing Synthyris subg. Plagiocarpus, Pennell (in Proc. Acad. Nat. Sci. Philadelphia 85: 86. 1933) established the name Synthyris Benth. subg. Synthyris (although using the designation "Eusynthyris"), and when this group is included in Veronica, V. subg. Synthyris (Benth.) M. M. Mart. Ort. & al. (in Taxon 53: 440. 2004) has precedence over a combination in Veronica based on S. subg. Plagiocarpus Pennell.
Ex. 28. The generic name Sigillaria Brongn. (1822), established for bark fragments, may in part represent the same biological taxon as the "cone-genus" Mazocarpon M. J. Benson (1918), which represents permineralizations, or Sigillariostrobus (Schimp.) Geinitz (1873), which represents compressions. Certain species of all three genera, Sigillaria, Mazocarpon, and Sigillariostrobus, have been assigned to the family Sigillariaceae. All these generic names can be used concurrently in spite of the fact that they may, at least in part, apply to the same organism.
11.10. The principle of priority does not apply above the rank of family (but see Rec. 16B).
