Brief Summary

provided by Ecomare
Round-leaved wintergreen has shiny leaves, open blossoms and a style that sticks out of the flower. This makes it easy to distinguish from lesser wintergreen. In addition, the stems of the leaves are longer than the leaf itself. Just like other wintergreens, its leaves stay green during the winter.

According to Haber (Syst. Bot. 8: 277–298. 1983), one of the main areas of taxonomic difficulty in Pyrola occurs in P. sect. Pyrola (see Křísa, Bot. Jahrb. Syst. 90: 476–508. 1971, for sectional subdivisions). The type of the section is P. rotundifolia Linnaeus, a white-flowered species common throughout Europe and eastward to just beyond Lake Baikal in Siberia (cf. Hultén, Amphi-Atlantic Pl. map 123. 1958). Numerous taxa, both white- and pink-flowered, have been recognized as segregates of this widespread species, or described as distinct but related to P. rotundifolia. The assessment of taxonomic affinities within this “complex” has been problematic because of the lack of clear morphological discontinuities (Haber & Takahashi, Bot. Mag. (Tokyo) 101: 483–495).
