PLANT: Taprooted perennial with 3-8(10) erect to ascending stems, often suffrutescent; stems 1-3(4) dm tall, sometimes loosely clumped, the internodes evident, glabrous to glandular and short villous. INFLORESCENCE: flowers 2-3, pedicelled; pedicels glandular to short pilose. FLOWERS: calyx 7-12 mm long, the membranes carinate to ridged at the base; corolla white to deep pink, the tube 12-30 mm long, the lobes 5-12(-15) mm long, obovate, obtuse; stamens inserted on the upper tube; stigmas located among the stamens. NOTES: Sandy to rocky soils, open sites, shrublands and woodlands; Apache, Cochise, Coconino, Gila, Mohave, Navajo, Yavapai cos.; 980-2070 m (3200-6800 ft); Apr-Jun; British Columbia to MT, s to e CA and NM. Geographic and ecological variation with respect to habit, leaf size, and floral morphology is complex throughout the range of the species and in much need of study. REFERENCES: Dieter H.
