Ginkgo biloba, common name Maidenhair tree, is the only living species in the division Ginkgophyta, all others being extinct. 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. Ginkgos are large trees, with an angular crown and long, somewhat erratic branches. It is usually deep rooted and resistant to wind and snow damage. Young trees are often tall and slender, and sparsely branched; the crown becomes broader as the tree ages. During autumn, the leaves turn a bright yellow, then fall, sometimes within a short space of time (one to 15 days). A combination of resistance to disease, insect-resistant wood and the ability to form aerial roots and sprouts makes ginkgos long-lived, with some specimens claimed to be more than 2,500 years old.
Ginkgoites australis, fossils have been found in Koonwarra just a few km's down the Tarwin River. They date from the early Cretaceous, 118–115 million years ago.
