The unique feature of the ginkgo tree is an ancient and spectacular living fossil of nature
Ginkgo biloba is the longest-living tree in the world and has a long and unique history. It belongs to the Ginkgo family and is the only one in the world.
It is a tree that can reach a height of more than 40 meters and a diameter of 4 meters. The bark of the small tree is shallowly longitudinally lobed, while the bark of the giant tree is grayish-brown with deep longitudinal fissures. The crown shape of ginkgo biloba varies depending on age. In juvenile and adulthood, its crown is conical, while older trees are broadly oval.
Ginkgo biloba leaves are nearly rounded and sloping upwards. The annual shoots are light brown and turn grayish-white after the second year, with small longitudinal cracks. The short branches are densely covered with grayish-black leaf spots, and larger branches can also grow on the short branches. The buds in winter are brownish-yellow, usually ovate, and blunt at the tip.
Ginkgo biloba leaves are fan-shaped, with large stems, light green in color, and no hairs. The leaves have many parallel bifurcated veins, and the apex is 5 8 cm wide. On shorter shoots, the leaves are usually wavy, while longer shoots are usually two. The leaves are wedge-shaped at the bottom. At the seedling or budding stage, the leaves crack more, and some leaves crack again. The leaves are scattered in a spiral pattern on annual shoots, with 3-8 in clusters on short branches. In autumn, the leaves turn yellow and then fall.
Ginkgo biloba is a unisexual flower that is monoecious. Males, females, and males form clusters in the scaly leaf axils at the top of short branches. The globular corolla of males is soft and low-hanging. Ginkgo biloba is a long-stemmed fruit that hangs. Its seeds are oval, oblong-obovate, oval, or nearly globular. Its main components are leukocarcinol, leukocarpol and leukotol.
Ginkgo biloba is a tall and majestic tree with fan-shaped leaves, dioecious plants, and highly toxic fruits. It occupies a very important place in both nature and human history.
