672137 Draba sibirica (Pall.) Thell.
- Thell., Lepidium: 318 in nota 2 (1906). - Lepidium sibiricum Pall., Reise Russ. Reich. 3: 34 (1776). Described from Siberia.
Geography: European (E) - Asian (N/C) & North American (Greenlandic, E).
Notes: Böcher (1974) distinguished between a large-grown subsp. sibirica from the Caucasus, southern Siberia, and the Altai and a small-grown subsp. arctica from northwestern Siberia, northern Russia, and Greenland. He cited several diagnostic differences. We accept the separation. All plants that reach the Arctic belong to subsp. arctica.
