Hello! I'm a law student trying to understand the variety protection system, so I need help from you experts. If I'm not wrong, plants are identified by a binomial name, which refers both to the genus and the species it belongs to. Also, a genus covers many species. Well, the international treaty says that each State should protect "at least 15 plant genera OR species". I'm confused by the conjuction OR, because protecting fifteen genera would mean much more than protecting fifteen species. Fifteen species could theorically all belong to the same genus, and in that case, that State would be protecting just one genus and fifteen species. On the other hand, the treaty could mean that each State has to protect fifteen genera, which would cover many more species. Could anyone please explain me this? It would be easier if the treaty said "fifteen genera" or "fifteen species"; but not "fifteen genera or species". Thank you very much!
