Darwin had a hard time explaining flowers but we will let Wolf-Ekkehard Lönnig tell it:
Editor’s note: Geneticist Wolf-Ekkehard Lönnig brings to our attention a new publication of his that we highly recommend: “On the Inordinate Amount of ‘Living Fossils’ in the Flowering Plants (Angiospermae).” What follows is the Abstract, in which all emphases have been added by Dr. Lönnig, a distinguished retired scientist from at the Max Planck Institute for Plant Breeding Research in Germany. For background, see mathematician Granville Sewell’s recent post, “Wolf-Ekkehard Lönnig: An Intelligent Design Pioneer.”
As illustrated for the monocots (virtually the same situation in the dicots1), the figure below shows that Darwin’s “abominable mystery” has become even more “abominable” and “mysterious” during the last 50 (not to speak of the last 150) years.

Note: Loennig fetched a pole and fished Matzke out of the tank, forcing the carnivorous plant to return to eating… bugs until it managed to acquire an account with DoorDash, after which it ate junk food exclusively.
