Plants 40–150 cm (stems sulcate to striate distally, densely glandular). Leaves cauline and/or basal; sessile; blades ovate to ovate-elliptic, 1.5 (cauline) –18 (basal) cm, bases shortly sagittate or clasping, margins acerose-denticulate, faces densely glandular-puberulent. Heads in subcongested corymbiform arrays. Involucres obconic to campanulate, 7–9 mm. Phyllaries in 2–3 series, oblong-oblanceolate, apices acuminate, abaxial faces densely glandular-hairy. Receptacles alveolate, glandular. Florets 3–6; corollas lavender-pink (purple), 7–12 mm. Cypselae subcylindric to subfusiform, 3–7 mm, glandular; pappi bright white, 8–9 mm (rigid). 2n = 54.


Phenology: Flowering Oct–Nov.
Habitat: Gravel and caliche soils in warm Sonoran desert scrub
Elevation: 100–200 m
