Anyway, such a pretty picture would certainly be possible if botanists
could only agree on genera ... and it's possible that such beasts are
available online, but by what I can see, Matthew didn't even try a google
search.


Judging by the results of a quick google, any such picture would be
inaccurate. The classification of Apiaceae, Araliaceae and allies is
being reworked in the light of DNA sequence data. (Apparently one
subfamily has been moved from Apiaceae to Araliaceae.) Diagrams of parts
of the cladogram should be available in the literature, but whether
they've all been put together is another matter. And generic limits are
apparently in need of revision.

Apiaceae has a pollen record back to the Eocene, and Araliaceae into the
Upper Cretaceous.
