Ginkgo leaf and berries from the maidenhair tree (Ginkgo biloba). This two-lobed leaf is unique among trees in that it has no midrib and no network of veins. Instead, the venation consists of a constantly branching fan of veins from the base of the leaf. The leaves turn a golden yellow in autumn. This species of maidenhair tree is the only living representative of the ancient Ginkgoales (family Ginkgoaceae). Ginkgo biloba has separate male and female plants. The tree is adaptable to almost any climate, and from China it was successfully introduced into Europe early in the 18th century.
