Taxonomy

The genus was traditionally included in the borage family, Boraginaceae sensu lato.^[4] It was assigned to the subfamily Ehretioideae, but molecular data revealed it to be more closely related to the genus Cordia, so that other authors placed in Cordioideae.^[5] Subsequently, it was placed in its own family, Coldeniaceae, within the Boraginales order, by the Boraginales Working Group.^[6] As of December 2025^[update], this placement is accepted by World Flora Online,^[3] but not by Plants of the World Online which retains it in a broadly circumscribed Boraginaceae.^[7]
