The Cruciferae family, particularly the
brassicaceae are long overdue for revision and re-classification IMHO.

What particular aspects worry you?

Quite a few. You might remember more than one discussion in urg about
'collards' and others about correct naming of broccoli/calabrese. New
gardeners are often caught out by rooted plants being brassicas and
Oriental mustards are becoming a minefield of their own.

Normally recreational gardeners do not concern themselves over much
about correct botanical naming. When vegetables are being grown in a
rotational system though, plant families, especially brassicas can be
very important in maintaining soil and plant health.
