| | Welwitschia |
 | | Some older references have suggested that the Gnetophyta may represent a "missing link" in the evolution of flowering plants, but others say that vessels and double fertilization are examples of parallel evolution. |  | | The leaves arise from a massive woody crown or trunk (caudex) in the center. |  | | Double fertilization was once thought to be a strictly angiosperm characteristic. |

| | gnetophyta |
 | | Gnetophyta's unique fertilization feature is that a tube grows from the eggs to unite with the pollen tubes in order for fertilization to take place between the gametophytes. |  | | Most flowering plants contain vessel elements, too, providing evidence to some botanists that the Gnetophyta might have been ancestral to angiosperms. |  | | The sperm themselves are not motile, like we see in the cycads and gingko. |
