Hogan and Elliot (2022) also report a voucher in the Great Sand Dunes Herbarium from a ridge between Medano and Little Medano canyons, a specimen they have not examined. D. cana has been recently given species status (elevated from D. breweri var. cana). Its habitat is rock ledges, talus slopes, and moist tundra meadows. In the Watershed, despite its variability the species is easily recognized since there are only two other drabas with white petals: Draba fladnizensis is four or less inches high, with leaves usually glabrous above, and with stems with three or less leaves; Draba smithii is low and mat forming. The USA distribution of D. cana largely is the Central Rockies, with isolated occurrences across the states bordering Canada.
