For example, the name "Endressia" (sensu Whiffin) was published in 2007 for a genus in family Monimiaceae, but is an illegitimate homonym of Endressia J.Gay in family Apiaceae.
To illustrate, the term "Endressia" (as described by Whiffin) was published in 2007 for a genus in the Monimiaceae family, however, it is an invalid synonym of Endressia J.Gay from the Apiaceae family.
