[Taxacom] Quick question regarding formation of some family names in botany

[Paul van Rijckevorsel]

This may not be a question with a clear answer.
As indicated, this will depend on the genitive
form of these generic names. Third-declension
nouns on -/is/ can be divided into four groups,
each with a different genitive form: on /-is/
(unchanged), on -/idis/, -/inis/, or -/itis/.

There is not necessarily close agreement on
what name gets what genitive. For a long
time there was a lively debate on the correct
spelling of the name of the family containing
/Capparis/. In the end those favouring
/Capparidaceae/ lost out to /Capparaceae/ when
the latter spelling was conserved.
