Taxonomy
The genus was formerly placed in the segregate family Taxodiaceae, it is now included in the monotypic subfamily Taiwanioideae of the family Cupressaceae. It is the second most basal member of the living Cupressaceae, with only Cunninghamia being more basal. Its lineage is thought to have diverged from the rest of Cupressaceae during the Middle Jurassic. The oldest fossil assignable to the genus is from the mid-Cretaceous (Albian-Cenomanian) of Alaska. Other fossils of the genus are known from the Late Cretaceous of Asia, the Eocene of Asia and North America, and the Miocene of Europe and Asia.
