908 Eutrema edwardsii R. Br.
This species has a wide arctic-montane distribution. Possibly the species E. compactum Schulz in the C. Asiatic mountains is included in the material used for this map. A closely related species, E. pentlandii Rollins, occurs in Colorado, U.S.A. E. edwardsii belongs to the circumpolar plants (Hultén, Circumpol. Il, p. 60, 325 and map 52).
