Ginkgoales

The Ginkgoales is an order of gymnospermous trees that first appeared in the Permian period. It is unique in that it is represented by only one living species, Ginkgo biloba. This tree, often called a "living fossil," is native to China and has existed for about 250 million years.12

The ginkgo tree is known for its fan-shaped, leathery leaves and its resilience to cold and urban pollution. While its wood has little economic value, the roasted seed kernel is considered a delicacy in some cultures. Extracts from the ginkgo leaf have been used in traditional Chinese medicine and are being investigated for their potential benefits in memory enhancement and the treatment of conditions like Alzheimer disease. Despite its historical significance and medicinal uses, Ginkgo biloba is listed as an endangered species in the wild.234
