Article 15. Names and nomenclatural acts published after 1960.
15.1. Conditional proposal. 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 126.96.36.199 and 51.3.3, and for those published in tentative combinations see Article 188.8.131.52).
15.2. Names published after 1960 with the term "variety" or "form" excluded. 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.
