Ginkgo biloba is the only living species in the division Ginkgophyta. Some specimens are claimed to be more than 2,500 years old. The leaves are unique among plants, being fan-shaped and radiating out into the leaf blade, sometimes bifurcating into anastomosing.
About Ginkgo biloba in brief
Ginkgo biloba is the only living species in the division Ginkgophyta, all others being extinct. The genus name Ginkgo is regarded as a misspelling of the Japanese gin kyo, which is derived from the Chinese 銀杏 used in Chinese herbalism literature. The tree has an angular crown and long, somewhat erratic branches, and is usually deep rooted and resistant to wind and snow damage. Some specimens are claimed to be more than 2,500 years old. The leaves are unique among plants, being fan-shaped and radiating out into the leaf blade, sometimes bifurcating into anastomosing. Two veins enter the base of the leaf and repeatedly in two; this is known as dichotomous venation and is also known as venation in two. The species shows a preference for disturbed sites; in the \”semiwild\” stands at Tianmu Mountains, many specimens are found along stream banks, rocky slopes, and cliff edges. It is a member of a very old genus, with some fossils dating back 200 million years. Native to China, the tree is widely cultivated, and was cultivated early in human history. It has various uses in traditional medicine and as a source of food. GinkGo prefers full sun and grows best in environments that are well-watered and well-drained. Old individuals are also capable of producing aerial roots on the undersides of large branches in response to disturbances such as crown damage; these roots can lead to successful clonal reproduction upon contacting the soil.
Ingos, as in other plants, allow the formation of new parts of leaves in the older parts of the crown. After a number of years, a short shoot may change into a long shoot, sometimes up to 15cm up to 10cm long, but never up to 5–10cm wide. The Leaves contain unique ginkgo biflavones, as well as alkylphenols and polyprenols. The branches grow in length by growth of shoots with regularly spaced leaves, as seen on most trees. They are arranged regularly on the branches on first-year growth except except on the short internodes of the short shoots, which are formed only on the first year of growth. Because of this, leaves appear to be clustered at the tips of the branches, with reproductive structures and other parts of plants that possess them, such as the ovaries and ovaries, being clustered at their tips. Some ginkgos are known as gingko, which means ‘ginkgo’ in Chinese and ‘gingko’ in English. The name of the tree’s genus is thought to have been misspelled by Carl Linnaeus in his book Mantissa plantarum II and has become the name of its genus. The spelling pronunciation is ˈɡɪŋkɡoʊ, which has given rise to the common other spelling \”gingko\”.
