163 Luzula pilosa (L.) Willd. and allied species.

The map shows L. pilosa (Europe and W. Asia) and some closely related species, viz. L. rufescens Fisch. in C. and E. Asia and NW. North America, L. plumosa E. Mey. in isolated C. Asiatic areas, L. japonica Buchen. (syn.: L. plumosa var. macrocarpa [Buchen.] Ohwi) in E. Asia and L. acuminata Raf. In N. America. Together these taxa form a circumpolar distribution pattern (Hultén, Circumpol. I, p. 186 and map 176). Cf. also Meusel et al. 1965, map p. 86.
