... swede is a brassica? A type of turnip, surely!

turnips are brassicas. So is mustard.

Only some of the culinary mustards (Brassica nigra, Brassica juncea) are
Brassicas, others aren't (Sinapis alba), at least by conventional
taxonomy.

(And there's garlic, hedge, hoary and treacle mustards, inter alia, to
muddy the pot.)
