CHAPTER III

NOMENCLATURE OF TAXA ACCORDING TO THEIR RANK

SECTION 6

NAMES OF ORGANISMS IN CULTIVATION

Article 28

28.1. Organisms brought from the wild into cultivation retain the names that are applied to them when growing in nature.

Note 1. Hybrids, including those arising in cultivation, may receive names as provided in Chapter H (see also Art. 11.9, 32.4, and 50).

Note 2. Additional, independent designations for special categories of organisms 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 (ICNCP), which defines the cultivar as its basic category (see Pre. 11).

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

Note 4. Epithets in names published in conformity with this Code are retained as cultivar epithets, included in single quotation marks, under the rules of the ICNCP when it is considered appropriate to treat the taxon concerned under that Code.

Ex. 1. Mahonia japonica DC. (Syst. Nat. 2: 22. 1821) may be treated as a cultivar, which is then designated as Mahonia ‘Japonica’; Taxus baccata var. variegata Weston (Bot. Univ. 1: 292, 347. 1770), when treated as a cultivar, is designated as Taxus baccata ‘Variegata’.

Note 5. The ICNCP also provides for the establishment of epithets differing markedly from epithets provided for under this Code.

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 in Folia Dendrol. 10: 292. 1998) was established for a tetraploid cultivar presumed to result from the original cross between J. chinensis L. and J. sabina L.
