336 Deschampsia caespitosa (L.) Beauv. var. glauca (Hartm.) Sam.
This mostly arctic-subarctic variety has an almost circumpolar distribution. However, it is doubtful whether all occurrences in N. America really belong to this taxon described from Scandinavia (cf. Hultén, Circumpol. I, p. 66). On the whole the distribution is uncertain.
