Menispermaceae, the botanical name for a family of flowering plants, has been universally recognized by taxonomists. Tubocurare, a neuromuscular blocker and active ingredient in curare, is derived from plants of this family.
The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes this family and places it in the order Ranunculales, in the clade eudicots.
It is a medium sized family of 70 genera totaling 420 extant species, mostly of climbing plants. The great majority of the genera are tropical, but with a few (notably Menispermum and Cocculus) reaching temperate climates in eastern North America and eastern Asia.
