Douglasia ochotensis is the only North American member of the genus to occur also in Asia; its range extends from the Sea of Okhotsk throughout the Bering Strait region, and across the Brooks Range to the Mackenzie River. It varies considerably with respect to flower size and degree of looseness in the growth habit; these characters are strongly affected by exposure, substrate stability, and moisture availability. Douglasia ochotensis can be easily distinguished from all other members of the genus by its prominent, imbricate, recurving, reddish brown, marcescent leaves.
"thin" is not a number.
