Quick Summary

The Ginkgoaceae is a family of gymnospermous plants that includes the genus Ginkgo and extinct plant genera. The sole living representative of this family is the Ginkgo biloba tree, often called a "living fossil" due to its ancient lineage, dating back approximately 250 million years.1234

Key Characteristics of Ginkgo biloba:

  • Appearance: The tree has fan-shaped, leathery leaves that resemble those of the maidenhair fern, giving it the nickname "maidenhair tree". It can grow to heights of 20 to 30 meters (65 to 100 feet).243
  • Resilience: Ginkgo trees are known for their resistance to fungi and insects, and their ability to tolerate cold weather and urban pollution.24
  • Reproduction: Ginkgo trees are dioecious, meaning male and female reproductive structures are on separate trees. The seeds have a fleshy outer layer that emits an unpleasant odor when decaying.34
  • Uses: Historically, ginkgo leaf extracts have been used in traditional Chinese medicine, and modern research investigates their potential for enhancing memory and treating conditions like Alzheimer's disease. The roasted seed kernel is also considered a delicacy in some cultures.234

Despite its resilience and historical significance, Ginkgo biloba is listed as an endangered species in the wild.4
