Euphorbia cyathophora is native to the midwestern and southeastern United States, Mexico, the West Indies, and northern South America. Leaf shape can be polymorphic on individuals of this species, but not to the extent as in E. heterophylla. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Euphorbia conferta is known only from Broward, Miami-Dade, and Monroe counties in southern Florida. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
