| The genus once included many more species, but was split several
decades ago into several genera; the naming of the genera has been
contentious, but a ruling of the International Code of Botanical
Nomenclature in 1999 resulted in the defining species of the genus
being changed to Chrysanthemum indicum, thereby restoring the
economically important florist's chrysanthemum to the genus
Chrysanthemum. These species were, after the splitting of the
genus but before the ICBN ruling, commonly treated under the genus
name Dendranthema |
