2 Families

• Buxaceae (boxwood) - 2 genera
• Daphniphyllaceae - 1 genus, Daphniphyllum, 35 species. The family is empty in ITIS. Delta http://biodiversity.uno.edu/delta/angio/www/daphniph.htm places 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 Delta http://biodiversity.uno.edu/delta/angio/www/pandacea.htm for more information.
• Simmondsiaceae (goatnut, jojoba) - 1 genus

Family Aextoxicaceae, which is assigned to order Euphorbiales in some older systems, is assigned to order BerberidopsidalesBerberidopsidaceae Aextoxicaceae The Berberidopsidales are a tiny order of dicotyledons, comprising the families Berberidopsidaceae and Aextoxicaceae. Under the older Cronquist system, the former was placed within the family Flacourtiaceae, and the latter in newer systems, including that of the Angiosperm Phylogeny Group.

3 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.
