"The Gingko tree, Ginkgo biloba, is the sole surviving species of a group of Gymnosperms that flourished 65 million years ago, the time when dinosaurs existed. Gingko trees are also called Maidenhair trees. It is the only living gymnosperm (which includes pines, firs, and spruces) that sheds its leaves during the fall. Ginkgo are not native to North America, rather they are indigenous to China, Japan, and Korea, where they may still exist in remote mountainous parts."
