Karafuto-Ibara (Sakhalin Briar) R. davurica Pall. var. alpestris (Nakai) Kitag. (syn. = R. marretti H. Lév.)
Neo-Lin. Fl. Manshur.:382 (1979)
Distribution: Hokkaido, Central Honshu
R. davurica var. alpestris is found in grassland and on forest margins in Hokkaido, and in some limited areas of central Honshu: Gunma and Nagano Prefectures. The flowers of this rose closely resembles that of R. rugosa, though it is a little smaller (3 to 4 cm across). Two, three, or more flowers are borne at the terminal of a small cane. The tree grows pretty tall, some reaching 2 metres or more. Its distinctive features are purplish coloured stems and reddish bracts at the base of a peduncle. It gives globular or ovoid fruits ca. 12 mm across. Its flowering period in C-Honshu is the beginning of July. Its fragrance is spicy, too, but less sweet than that of R. rugosa.

Botanical roses on the territory of the USSR, whose independence requires precising...
R. marretii Lévl. - according to Tolmatschew very similar to R. amblyotis C. A. Mey., no reason to classify as an independent species; according to Juseptschuk differs by its high fertility from R. amblyotis; a critical investigation is required; the existence of transitional forms does not justify the classification as an independent species. According to Woroschilow R. amblyotis C. A. Mey.
