Rosadavurica var. rubro-stipulata (Rosaceae), the correct name for R.davurica var. alpestris

The name Rosadavuricavar.alpestris (Nakai) Kitag. was published in 1979 as a new combination based on R.rubro-stipullatavar.alpestris Nakai. It is generally accepted as a deciduous shrub occurring in Russia, Manchuria, Japan, and the northern part of the Korean Peninsula and is distinguished by the presence of eglandular leaves. Rosarubro-stipullatavar.alpestris was originally described as a new variety with a leaf size relatively smaller than that of R.rubro-stipullatavar.rubro-stipullata . However, the observation of various specimens showed the leaf size of var.alpestris to be of minor importance, and it was included in var.rubro-stipullata as a synonym. Due to the priority of autonyms, a new combination is required to replace R.davuricavar.alpestris. Additionally, it should be noted that the epithet “rubro-stipullata” is derived from the Latin word “stipula” rather than “stipulla.” Therefore, for this variety, we propose a new combination, R.davuricavar.rubro-stipulata (Nakai) D.
