Taxodiaceae

The Taxodiaceae were at one time regarded as a distinct plant family comprising the following ten genera of coniferous trees:

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 is 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.

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

Evolution
Fossil leave of Taxodium dubium, 8 Mio. years old, Hambach lignite open cast mine, Germany

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

gollark: *Physical* requirements? Why?
gollark: Maybe someone will make magic everything-producing nanofabricators at some point, but *now* we don't have that and everything has to come out of very complex supply chains involving many large factories.
gollark: You do actually need big nonlocal things to get economies of scale so we can have nice things like any advanced technology whatsoever.
gollark: It's not "weird mesh [REDACTED]". It's just a point to point link. You configure the allowed IPs on each end.
gollark: You can't really *know* if a provider has logs or not.
