The dogbane family (Apocynaceae) includes herbs, shrubs, vines, and trees with milky sap containing alkaloids and cardiac glycosides. The flowers are typically five-petaled and often showy with a tubular corolla. Many species in this family are highly toxic but also source of important cardiac medications.
General Description
