The base is wide and wedge-shaped, and the stem is 3- 10 cm (mostly 5-8 cm). Leaves on young trees and budding branches often split deeply (length 13 cm, width 15 cm), and sometimes the leaves split again (similar to the leaves of more primitive fossil species), and the leaves are spirally scattered on annual branches and short branches.
Cone dioecious, unisexual, clustered in the axils of scaly leaves at the top of short branches; The male cones are inflorescence-shaped, drooping, with loose stamens, short peduncle, 2 anthers, long oval, longitudinally dehiscent anthers, and no drug-separated hairs.

Ginkgo biloba is a rare tree species left over from Mesozoic era, and it is a special product in China. There are only wild trees in Tianmu Mountain, Zhejiang. They are born in acidic yellow soil with good drainage at an altitude of 500- 1000 meters, and often mix with coniferous and broad-leaved trees such as Cryptomeria fortunei, Torreya grandis and Orchidaceae, and grow vigorously.
Ginkgo biloba is cultivated in a wide range: from Shenyang in the northeast in the north to Guangzhou in the south, with an altitude of 40- 1000 meters in east China, and Guizhou and western Yunnan (Tengchong) with an altitude of less than 2000 meters in southwest China to produce seeds or as garden trees.
Seedlings, transplanted seedlings or tillers are often grafted in the cultivation area, which can blossom and bear fruit 8- 10 years in advance (seedlings usually start to bear seeds after 20 years). Ginkgo biloba cultivated everywhere is hundreds or thousands of years old. It is cultivated in gardens in Korea, Japan, Europe and the United States.
