I went through it with my browser's search engine, looking for "Brassica".
However, I don;'t know enough to guess whether two Brassicas with the same cultivar name but different sepcies names are:
- mistaken species names
- older species names that have since been corrected or widely agreed upon
- two real, different plants of different specues that happen to have the same cultivar name.
Short form: I dunno.
