The Brassicales are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system. One character common to many members of the order is the production of glucosinolate compounds. Most systems of classification have included this order, although sometimes under the name Capparales.

The rosids are members of a large clade of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms.
