curbita and Citrullus and the species Cucumis melo. Consequently, for example, the
use of the convenient cultivar-group names Lactuca sativa Cutting Group and Cichorium
endivia Cutting Group for groups of cultivars of similar use practice in these
two species, is not permitted, and one of these names must be replaced (see Fig. 2).
The same applies to the names Cucurbita maxima Austroamerican Group, and Cucurbita
moschata Austroamerican Group, for groups of primitive cultivars or landraces
of these two species with similar geographical provenance (see Fig. 3).
Nonetheless, I have considered it useful to adopt these names for the groups concerned
in the new “Mansfeld” (HANELT and INSTITUTE OF PLANT GENETICS AND CROP
PLANT RESEARCH 2001).

A. Note that the use of the two “Cutting Group” names is contrary to the
provisions of Article 6.1 of the ICNCP, as both species fall within the
same denomination class (ICNCP, Appendix IV).
B. The species Lactuca sativa L. was transferred by SHIH in 1988 to his
newly-established genus Pterocypsela Shih. Does this constitute division
of a denomination class under Article 6.3 of the ICNCP? See also
Article 6.3, Note 2.
