I tackled the Brassica species after dinner, deleted all of the invalid names, checked to make sure all of the validly entered names were accepted, recategorized some as synonyms of accepted names, deleted the entries that were synonyms after moving pictures, comments, and other data, and then went cross-eyed and had to stop. I didn't go through the named cultivars, but I'm sure that some of the species entered for those names are also synonyms.
