Taxonomy
notes
The very closely related D. obénsis Roshev. is reported from Chukchi Peninsula; the report needs confirmation. A plant probably belonging to D. Mackenzieana Raup and very closely related to D. beringensis occurs at mouth of Mackenzie River. Both reports are indicated on Alaskan map by question marks.
