The Taxodiaceae was at one time regarded as a distinct Family comprising 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, as there is no consistent character by which they can be separated, and they also show strong genetic similarity; this classification is now becoming widely accepted. The exception, Sciadopitys, is genetically very distinct from all other conifers, and is now included in a family of its own, the Sciadopityaceae.
