Rosa xanthina Hook.f. (1899) is a synonym of Rosa ecae. When Rosa ecae was first introducted to Europe after 1880, botanists declared that it was Rosa xanthina as described by Lindley in 1820. Botanists have since determined that the two species are either distinct species or different varieties of a single species.

Belongs to the Pimpinellifolia section (styles free, shorter than the stamens, blooms solitary, without bracts). Has doubly serrated leaflets that are glandular beneath, like R. primula and R. foetida. It differs from R. primula in having fewer leaflets, smaller blooms and in the colour of hips. It differs from R. foetida in its smooth leaves, smaller blooms, and lack of the distinct Foetida scent of linseed oil.
