The Taxodiaceae was at one time regarded as a distinct plant family comprising the following ten genera of coniferous trees:
- Athrotaxis
- Cryptomeria
- Cunninghamia
- Glyptostrobus
- Metasequoia
- Sciadopitys
- Sequoia
- Sequoiadendron
- Taiwania
- Taxodium
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, Sciadopityaceae.
