Ginkgoales

(botany) An order of gymnosperms composing the class Ginkgoopsida with one living species, the dioecious maidenhair tree (Ginkgo biloba).

An order of nearly extinct gymnosperms (Pinophyta) having only one living species, the maidenhair tree (Ginkgo biloba). The fan-shaped leaves resemble those of the maidenhair fern. The leaves are dichotomously veined (fork-veined) and often more or less lobed. The species is dioecious; that is, the male and female reproductive structures occur on separate trees. Ginkgo is widely planted on street borders, on home grounds, and in city parks. See also Pinophyta.
