Brassicales

The Brassicales (or Cruciales) are an order of flowering plants, belonging to the malvid group of eudicotyledons under the APG IV system. Well-known members of Brassicales include cabbage, cauliflower, Brussels sprout, broccoli, kale, mustard, turnip, bok choy, rapeseed, radish, horseradish, caper, papaya, moringa or drumstick tree, mignonette, nasturtium, and arabidopsis.

One character common to many members of the order is the production of isothiocyanate (mustard oil) compounds. Most systems of classification have included this order, although sometimes under the name Capparales (the name chosen depending on which is thought to have priority).
