6-562: Vochysiaceae is a plant family belonging to the order Myrtales . Trees or shrubs with opposite leaves; flowers are zygomorph 1-(3)-5 merous ; ovary inferior or superior; one fertile stamen; fruits samara or capsules . Six of the eight genera are native to the Neotropics . The genera Erismadelphus and Korupodendron are native to West and Central Africa. The family likely originated in South America . Erismadelphus
12-539: Is thought to have diverged from Erisma approximately 30 million years ago, and traveled to Africa as the result of long-distance dispersal. Vochysiaceae are closest to Myrtaceae . Vochysiaceae consist of 7 genera with 217 species. The family is classified into 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,
18-516: Is unrelated and now stands alone in the family Euphroniaceae , more closely related to the family Chrysobalanaceae . Myrtales The Myrtales are an order of flowering plants (angiosperms) placed as a sister to the eurosids II clade as of the publishing of the Eucalyptus grandis genome in June 2014. The APG III system of classification for angiosperms still places it within
24-785: The eurosids ; this is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APG III: The Cronquist system gives essentially the same composition, except the Vochysiaceae are removed to the order Polygalales , and the Thymelaeaceae are included. The families Sonneratiaceae , Trapaceae , and Punicaceae are removed from
30-584: The Lythraceae. In the classification system of Dahlgren the Myrtales were in the superorder Myrtiflorae (also called Myrtanae). The APG III system agrees with the older Cronquist circumscriptions of treating Psiloxylaceae and Heteropyxidaceae within Myrtaceae, and Memecyclaceae within Melastomataceae. Ellagitannins are reported in dicotyledoneous angiosperms, and notably in species in
36-677: The order Myrtales. Myrtales is dated to around 89–99 million years ago (mya) in Australasia ; however, there is some contention as to that date, which was obtained using nuclear DNA . When looking at chloroplast DNA , the myrtales' ancestor is, instead, considered to have evolved during the mid-Cretaceous period (100 mya) in Southeast Africa , rather than in Australasia. Although the APG system classifies myrtales as within
