Taxodiaceae is a formerly recognized conifer family. It is today recognised as a paraphyletic grade of basal lineages within the Cupressaceae. It contains the following living genera:

As proposed, genera of the former Taxodiaceae are grouped in the following subfamilies within the larger Cupressaceae:

Athrotaxidoideae Quinn (Athrotaxis)
Cunninghamioideae (Sieb. & Zucc.) Quinn (Cunninghamia)
Sequoioideae (Luerss.) Quinn (Sequoia, Sequoiadendron, and Metasequoia)
Taiwanioideae (Hayata) Quinn (Taiwania)
Taxodioideae Endl. ex K. Koch (Taxodium, Glyptostrobus, and Cryptomeria)[1]

Evolution

In earth's history Taxodiaceae were widespread. They are known since the Jurassic and can be found as fossil from Tertiary times.

-However, recent research has shown that the Taxodiaceae, with the single exception of ''Sciadopitys'', should be merged into the Family [[Cupressaceae]]. There are no consistent characters by which they can be separated, and genetic evidence demonstrates close relationships; this merging now becoming widely accepted. The one exception, the Genus ''Sciadopitys'', is genetically very distinct from all other conifers, and now treated in a family of its own, [[Sciadopitys|Sciadopityaceae]].
