  Euphorbiaceae - Wikipedia, the free encyclopedia
The Spurge family (Euphorbiaceae) is a large family of flowering plants with 280 genera and around 6,000 species.
The Euphorbiaceae is a complex family with a notoriously difficult circumscription.
A former fifth subfamily (the Phyllanthoideae) has been separated from the Euphorbiaceae as a result of lineage analysis and now is treated as the Family Phyllanthaceae.

The family Euphorbiaceae is a complex family formed by 4 subfamilies: The (by far the largest one), the, the and the.
These groups are in turn subdivided into numerous tribes, subtribes and genera.
A former fifth subfamily (the) has been separated from the Euphorbiaceae as a result of lineage analysis: all of its tribes are now part of the newly-erect Phyllanthaceae except the tribe, which now forms a family in itself (the Putranjivaceae).

Many members are important food sources; others are useful for their waxes and oils and as a source of medicinal drugs; dangerous for their poisonous fruits, leaves, or sap; or attractive for their colourful bracts (leaflike structures located just below flower...
The phylogenetic relationships and biogeographic history of the Euphorbiaceae have been debated since the classic essay published by the British botanist George Bentham in the Botanical Journal of the Linnean Society (London) in 1878.
The movements of the larvae feeding on the pulp within the seed, which are intensified by warmth, give the seed the familiar jumping movement.

 PBIO 450 Lecture Notes - Rosidae -- Spring 1998
In defense of Cronquist, he is correct that the "Euphorbiaceae are so diverse in vegetative and chemical features and in pollen-morphology that one could compare some members of the group to any of a wide range of families and orders of dicotyledons" (p.
While the closeness of Pandaceae to Euphorbiaceae is not in doubt, the relationships of Buxaceae and Simmondsiaceae to the euphorbs are a concern.
The Simmondsiaceae are clearly unrelated to Euphorbiaceae and now assigned to their own order, Simmondsiales, and placed in the Hamamelididae rather than the Rosidae.

 ARS | Publication request: An Update on Development of An Est-Database for Euphorbiaceae.   (Site not responding. Last check: 2007-11-07)
Several research groups have realized the potential of using a genomics-based approach to, for example, identify markers and increase our knowledge of plant genome structure, organization and gene function within the Euphorbiaceae family.
As part of a genomics-based approach, an EST- (expressed sequence tag) database for Euphorbiaceae is being developed.
These new ESTs will be added to the developing database and, taken together, these resources will provide a valuable resource for breeding programs working on improving genetic stocks of desirable species and for scientist involved in developing methods to control the growth of undesirable species.

The Euphorbiaceae are mostly monoecious herbs, shrubs, and trees, sometimes succulent and cactus-like, comprising one of the largest families of plants with about 300 genera and 7,500 species that are further characterized by the frequent occurrence of milky sap.
The leaves are mostly alternate but may be opposite or whorled and they are simple, or compound, or sometimes highly reduced.
The tiny stamens are very numerous, up to 1,000 per staminate flower.
