Euphorbiales is the botanical name of an order of flowering plants. Such an order has been recognized by relatively few taxonomists.

In the APG II system (2003) the plants involved are placed in order Malpighiales. A well known system that did recognize such an order was the Cronquist system (1981) which placed the order in subclass Rosidae and used this circumscription:

order Euphorbiales
family Buxaceae

family Simmondsiaceae

family Euphorbiaceae

family Pandaceae

This usage of family Euphorbiaceae is in the wide sense: since that time the family has been split.

-== Families, formerly comprised in Euphorbiales ==
-* [[Buxaceae]] (boxwood) - 2 genera
-* [[Daphniphyllaceae]] - 1 genus, Daphniphyllum, 35 species.  The family is empty in ITIS.  [http://delta-intkey.com/angio/www/daphniph.htm Watson and Dallwitz] place it in [[Saxifragales]]
-* [[Euphorbiaceae]] (spurge) - 71 genera, including [[cassava]], [[castor bean]] and [[Poinsettia]]
-* [[Pandaceae]] - 4 genera, 28 species.  This family is empty in ITIS.  See  [http://delta-intkey.com/angio/www/pandacea.htm Watson and Dallwitz] for more information.
-* [[Simmondsiaceae]] (goatnut, jojoba) - 1 genus
+[[Category:plant taxonomy]]
-Family [[Aextoxicaceae]], which is assigned to order Euphorbiales in some older systems, is assigned to order [[Berberidopsidales]] in newer systems, including that of the APG.
+<!-- [[category:Rosidae]] -->
-== Ethnobotany ==
-Some of these species are highly toxic.
-In the [[Mediterranean]] area, some use euphorbia's leaves for fishing in rivers: leaves release their toxic substance, that goes immediately in solution with water, and when the fish is reached by it its swim-bladder swells until it explodes, killing the fish. The dead fish comes then to the surface and is easily collectible. This practice is however extremely unsafe, given that the toxic element remains in the tissues of the fish, so it would be dangerous to eat it.
