Article 15. Names and nomenclatural acts published after 1960
A new name or nomenclatural act proposed conditionally and published after 1960 is not thereby made available. A new name or nomenclatural act proposed conditionally and published before 1961 may be available (for Articles concerning type fixation see Articles 67.2.5 and 67.5.3; for species-group names first published at the same time as conditionally proposed generic names see Articles 188.8.131.52 and 51.3.3, and for those published in tentative combinations see Article 184.108.40.206).
A new name published after 1960 expressly as the name of a "variety" or "form" is deemed to be infrasubspecific and as such is not regulated by the Code [Art. 1.1.1] and is excluded from its provisions [Arts. 1.3.4, 45.6.3].
15.2.1. For names published before 1961 for "varieties" or "forms" see Article 45.6.4.
