Of conservation concern. Potentilla demotica is known from a single granitic knoll in the Hualapai Mountains, Mohave County. The species was reported as a western range extension of P. subviscosa by M. Butterwick et al. (1991); it differs in rock-dwelling habit, petal color, and epicalyx, among other characters.
