Maidenhair tree (Ginkgo)
Ginkgo trees have leaves similar to those found in some 300-million-year-old fossils. Unlike many gymnosperms, the leaves have wide blades with veins that fan out from their base. Long thought extinct in the wild, it is now known in the wild at two patches in China. Fertilization of ovules occurs via motile sperm, as in cycads and ferns.
