CHAPTER III. NOMENCLATURE OF TAXA ACCORDING TO THEIR RANK

SECTION 6. NAMES OF PLANTS IN CULTIVATION

Article 28

28.1. Plants brought from the wild into cultivation retain the names that are applied to the same taxa growing in nature.

Note 1. Hybrids, including those arising in cultivation, may receive names as provided in App. I (see also Art. 11.8, 40, and 50).

Note 2. Additional, independent designations for special categories of plants used in agriculture, forestry, and horticulture (and arising either in nature or cultivation) are dealt with in the International code of nomenclature for cultivated plants, where the term "cultivar" is defined and regulations are provided for the formation and use of cultivar epithets.

Note 3. Nothing precludes the use, for cultivated plants, of names published in accordance with the requirements of the botanical Code.

Note 4. Epithets in names published in conformity with the botanical Code may be used as cultivar epithets under the rules of the International code of nomenclature for cultivated plants, when cultivar is considered to be the appropriate status for the groups concerned.

Ex. 1. Mahonia japonica DC. (1821) may be treated as a cultivar, which is then designated as Mahonia 'Japonica'; Taxus baccata var. variegata Weston (1770), when treated as a cultivar, is designated as Taxus baccata 'Variegata'.

Note 5. The International code of nomenclature for cultivated plants provides for the establishment of cultivar epithets differing markedly from epithets in Latin form.

Ex. 2. Disophyllum 'Frühlingsreigen'; Eriobotrya japonica 'Golden Ziad' and E. japonica 'Maamora Golden Yellow'; Phlox drummondii 'Sternenzauber'; Quercus frainetto 'Hungarian Crown'

Ex. 3. Juniperus pfitzeriana 'Wilhelm Pfitzer' (P. A. Schmidt 1998) was established for a tetraploid cultivar presumed to result from the original cross between J. chinensis L. and J. sabina L.
