Coldenia
Coldenia, named after C. Colden, is a genus of flowering plants in the family Coldeniaceae. It is the only genus in the family., the sole accepted species is Coldenia procumbens.
Taxonomy
The genus was traditionally included in the borage family, Boraginaceae sensu lato. 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. Subsequently, it was placed in its own family, Coldeniaceae, within the Boraginales order, by the Boraginales Working Group., this placement is accepted by World [Flora Online], but not by Plants of [the World Online] which retains it in a broadly circumscribed Boraginaceae.
