Order of dicot flowering plants From Wikipedia, the free encyclopedia
The Brassicales (or Cruciales) are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system.[2] One character common to many members of the order is the production of glucosinolate (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).[3]

On 20 April 2020, a newly described monotypic species from Namibia, namely, Tiganophyton karasense Swanepoel, F.Forest & A.E. van Wyk is placed under this order as a monotypic member of new family Tiganophytaceae, which is closely related to Bataceae, Salvadoraceae and Koeberliniaceae.[6]
Under the Cronquist system, the Brassicales were called the Capparales, and included among the "Dilleniidae". The only families included were the Brassicaceae and Capparaceae (treated as separate families), the Tovariaceae, Resedaceae, and Moringaceae. Other taxa now included here were placed in various other orders.
The families Capparaceae and Brassicaceae are closely related. One group, consisting of Cleome and related genera, was traditionally included in the Capparaceae but doing so results in a paraphyletic Capparaceae.[3] Therefore, this group is generally now either included in the Brassicaceae or as its own family, Cleomaceae.[4][7]
Setchellanthaceae is sometimes known as the azulita family.[8]
