Vochysiaceae
Vochysiaceae is a plant family belonging to the order of Myrtales. Description. Trees or shrubs with opposite leaves; flowers are zygomorph 1-(3)-5 merous; ovary inferior or superior; one fertile stamen; fruits samara or capsules. Biogeography. Six of the eight genera are native to the Neotropics. The genera "Erismadelphus" and "Korupodendron" are native to West and Central Africa. Evolutionary history. The family likely originated in South America. "Erismadelphus" is thought to have diverged from "Erisma" approximately 30 million years ago, and traveled to Africa as the result of long-distance dispersal. Systematics. Vochysiaceae are closest to Myrtaceae. Vochysiaceae consist of  7 genera with 217 species. The family is classified in two tribes: Tribe Erismeae : one inferior ovary and winged fruits Tribe Vochysieae: three fused superior ovaries and capsule fruits The genus "Euphronia", previously included in Vochysiaceae, is unrelated and now stands alone in the family Euphroniaceae, more closely related to the family Chrysobalanaceae.
