Plants
of the Spurge Family are herbs, shrubs or trees, usually with milky juice, which
is often poisonous. Many are
succulents and cactus-like. The
leaves are simple. The flowers have
stamens or pistils, not both, and may or may not have petals and sepals. Showy bracts, as in cultivated Poinsettias and
Crown-of-thorns, often simulate petals. Rubber
comes from a plant in this family as does castor oil and tung oil.
There
are over 280 genera of the Euphorbiaceae in the world but only 11 are native to
California. (Dale 106).
