Gnetophyta

Gnetophyta Gnetophyta is a division of gymnosperms encompassing approximately 70 extant species across three genera. These woody plants exhibit a range of forms, including trees, shrubs, and lianas. Gnetophytes possess unique reproductive structures, such as ovulate strobili, and some exhibit angiosperm-like features like vessel elements and double fertilization. Their leaves vary, with Gnetum species resembling angiosperm leaves in form and venation. Reproductive strategies are diverse, involving both wind and insect pollination. Welwitschia mirabilis, a notable gnetophyte, features only two leaves throughout its life, while other species have simple leaves arranged oppositely or in whorls.
