Discussion

Myurella sibirica is common in the East but becomes rare in northwestern North America. Small, slender, glaucous plants with widely spaced leaves and very large papillae distinguish this species. The leaves end in a rather long, slender apiculus, and the margins are distinctly and irregularly serrulate. The large central papillae and strongly toothed leaf margins distinguish this species from M. julacea and M. tenerrima.
