Notes: Elven and Petrovsky: Stellaria longipes s. str. is probably a mainly boreal North American taxon (with type from the nemoral zone at Kingston on Lake Ontario). Hultén (1943a), however, accepted it with a nearly circumboreal-polar range from northeastern European Russia eastwards through northern Asia and North America to Greenland. Petrovsky previously assumed that this species occurs in Siberia but neither in European Russia nor in the Russian Far East where it is replaced by S. peduncularis. Neither Vlasova (1993) nor Palvola and Bezdeleva (1996) reported S. longipes from, respectivelly, Siberia or the Russian Far East. All Eurasian reports needs confirmation. A chromosome count reported by Cai and Chinnappa (1989) suggests that diploid S. longipes s. str. is part of the parentage of the complex.
