> RE: homotypic synonyms -- in zoology we don't generally use that term (though I think we should), which I gather in non-zoological contexts usually refers to the "same" epithet combined with different genera (e.g., a basionym is a homotypic synonym of a subsequent combination).  However, we do have the notion of "objective synonyms", such as when the same specimen has been designated as the name-bearing type for two different species-group epithets (with different spellings, authorships, protologues*, etc.)  This is not common, but sometimes happens by accident, and sometimes is done on purpose.  But I wonder:  do you have situations in Botany where synonyms are "homotypic", even if they are not the "same" epithet combined with different genera (i.e., in cases where they are truly different epithets)?

Sure, firstly, whenever a name is preoccupied, and
a different epithet needs to be adopted (a replacement

Secondly, in cases where a move to a different genus
would result in a tautonym (when /Leontodon taraxacum/
is moved to /Taraxacum/, the tautonym cannot be published;
the species is named /T. officinale/).

Thirdly, when a move to a different rank is made for the
first time, a different epithet may be chosen ("A name has
no priority outside the rank at which it is published").

And fourthly, as you say, when authors assign the same
type, for different names.
