Gnetum is a genus of about 30-35 species of gymnosperms, the sole genus in the family Gnetaceae and order Gnetales. They are tropical evergreen trees, shrubs and lianas. Unlike other gymnosperms they possess vessel elements in the xylem. Some species have been proposed to have been the first plants to be insect pollinated as they occur in association with the extinct pollinating scorpionflies.[1]
Many Gnetum species are edible, with the seeds being roasted, and the foliage used as a leaf vegetable. Some are also valued in herbal medicine.
