Leaves: Basal and cauline, alternate, simple, elliptic, lanceolate, or ovate, 2-7 cm long, 1-3 cm wide, glabrous, margins entire; basal and lower cauline blades short- petiolate, upper cauline blades sessile. Flowers: Inflorescence of numerous flowers arranged in panicle- like cymes, the branches often elongating in fruit; pedicels strigose; calyx 2.5-4 mm long, divided nearly to the base, the lobes linear-lanceolate, glabrous or pubescent, the margins the lobes rounded; flowers June- September. Fruits: Nutlets 4, with a distinct, reflexed margin. Ecology: Pine forests; 1800-2700 m (6000-9000 ft); Coconino, Gila, Mohave, and Yavapai counties; endemic to Arizona. Notes: Mertensia franciscana is distinguished from M. macdougalli by strigose pubescence on the upper surfaces of the leaves, strigose pedicels, calyx divided nearly to the base, and the lobes of the calyx with a fringe of hairs.
