Interesting you should ask.  I've just compiled a list of the species of
Campanulaceae s. lat. recognized in the taxonomic literature since 1940.
The only synonyms included are those that have been used (accepted) during
that period.  Even constrained thusly, it averaged out to a 1.6-to-1 synonym
to accepted name ratio.
