1075 Rosa majalis Herrm.

Syn.: R. cinnamomea L. 1759

This species occurs spontaneously in Eurasia. The limit of its fairly common occurrence is tentatively drawn. It has been introduced for ornamental purpose into many European countries, where it is partly naturalized (cf. Fl. Eur. 2/1968, p. 27), as well as in eastern N. American. Closely related species take over eastwards, viz. R. jacutica Juz. in the Lena River area, R. davurica Pall. E of Baikal R. maretii Lévl. In Sakhalin and R. amblyotis C.A.M. in Kamchatka and Sakhalin. Cf. also Meusel et al. 1965, map p. 224.
