Systematics

The genus Chione was erected by

biological type for the genus are those plants which de Candolle called Chione glabra.[4] These are now included in Chione venosa var. venosa but per ICN, Chione glabra retains its status as type.[5]

Some authors have assigned as many as 15 species to Chione,[6] but usually only one species is recognized, Chione venosa.[7] In 2003, two species were removed from Chione and placed in a new genus, Colleteria.[5] The remaining species of Chione were combined into one species, Chione venosa, with four varieties.[5] Chione and Colleteria are the only genera in the subfamily Cinchonoideae that have not been assigned to a tribe. They will be placed in a tribe, possibly a new one, after further morphological study.[8]
