Ginkgoidae is a subclass of Equisetopsida in the sense used by Mark W. Chase and James L. Reveal in their 2009 article "A phylogenetic classification of the land plants to accompany APG III."^[1] This subclass contains the single extant genus Ginkgo under order Ginkgoales, family Ginkgoaceae.^[2] Its only extant species is Ginkgo biloba, the Maidenhair Tree.
