The
genus ''Carduelis''
is a group of birds in the
finch family Fringillidae.
The genus ''Carduelis'' was introduced by the French zoologist
Mathurin Jacques Brisson in 1760 by
tautonomy based on
Carl Linnaeus's
specific epithet
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ...
for the European goldfinch ''Fringilla carduelis''. The name ''carduelis'' is the
Latin word for the European goldfinch.
Many bird species were at one time assigned to the genus, but it became clear from

polyphyletic. The polyphyletic nature of the genus was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into several

In Greek mythology, the name Chloris (; Greek Χλωρίς ''Chlōrís'', from χλωρός ''chlōrós'', meaning "greenish-yellow", "pale green", "pale", "pallid", or "fresh") appears in a variety of contexts. Some clearly refer to different char ...
