225 Poa palustris L.

This widespread species has a circumpolar distribution (Hultén, Circumpol. I, p. 122 and map 114). Outlying localities may be adventive. The knowledge of the Siberian distribution is incomplete (cf. Tolmatchev in Fl. Aret. URSS 2/1964, p. 151). Cf. also Meusel et al. 1965, map p. 33.
