Gnetaceae is a family of seed plants that includes three main genera: Gnetum, Ephedra, and Welwitschia. These plants are unique because they share characteristics with both angiosperms (flowering plants) and gymnosperms (non-flowering seed plants). Gnetaceae species can be found in various habitats, from tropical rainforests to arid deserts. Members of the Gnetaceae family are known for their diverse forms and adaptations. For example, Welwitschia is famous for its long-lived, strap-like leaves, while Ephedra is often found in dry regions and has jointed stems. These plants play important ecological roles and have various uses in traditional medicine and industry.
