The plant division Gnetophyta or gnetophytes consists of three genera of woody plants grouped in the gymnosperms. The living Gnetophyta are in the genera Gnetum (family Gnetaceae), Welwitschia (family Welwitschiaceae), and Ephedra (family Ephedraceae). The gnetophytes differ from other gymnosperms (conifers, cycads, and ginkgos) in having vessel elements as in the flowering plants. In some classifications, all three genera are placed in a single order (Gnetales) but in others distributed among three orders, each containing a single family and genus. Most morphological and molecular studies confirm that Gnetum and Welwitschia diverged from each other more recently than from Ephedra. From Wikipedia under the
