Atlas of North European vascular plants
Hultén & Fries 1986
1034 Saxifraga oppositifolia L. subsp. glandulisepala Hult.
The map shows total ranges of two subspecies of S. oppositifolia, viz. subsp. glandulisepala Hult., with a fairly large distribution area in E. Asia and northern N. America, and subsp. smalliana (Engl. & Irmsch.) Hult. with a disjunct distribution in about the same area. They are not shown on map no. 1033. Together with S. oppositifolia s. str. a circumpolar distribution pattern is formed (cf. also Meusel et al. 1965, map p. 205, and Hultén, Circumpol. Il, map 62).
