My chief amateur's hate is the introduction of the rule that a family
must have a genus with the name that produces the name of the family -
Hence long entrenched family names Umbilliferae and Brassicaceae were
thrown out of the window.

***
Actually there is no such rule: it is perfectly within the rules to use
Umbelliferae. It has become somewhat unfashionable, but any complaints
should be directed against the writers of flora's and textbooks, not against
the rules.

The confusion you note is probably worse at the level of order and above.
