Shrubs, 50-200 cm. Stems branched from near bases, glandular-pubescent. Leaves alternate; petioles 5-60+ mm; blades 3-nerved from bases, ovate to deltate, 10-100 × 10-90 mm, bases cordate to truncate, margins crenate to serrate, apices acute to rounded, faces puberulent to glabrate, often gland-dotted. Heads borne in (leafy) paniculiform arrays. Peduncles 1-5 mm, glandular-pubescent. Involucres cylindric to obconic, 7-12 mm. Phyllaries 21-35 in 5-6 series, greenish, often purple-tinged, 3-4-striate, unequal, margins scarious; outer ovate to lance-ovate (glabrous or sparsely glandular-pubescent, apices acute to acuminate), inner lanceolate (glabrous, apices obtuse to acuminate). Florets 8-12; corollas pale yellow-green, 5.5-8 mm. Cypselae 2.5-3.5 mm, puberulent; pappi of 24-30 white, barbellate bristles. 2n = 18. Flowering Jul-Oct. Dry, rocky hillsides, arroyos, canyons; 800-2700 m; Ariz., Calif., Colo., Idaho, Nev., N.Mex., Okla., Tex., Utah, Wyo. Floret number of 18 is reported for Brickellia californica in most floras; A. Cronquist (1994) noted that 18 is high by his count; he reported 12 as the maximum number for the specimens he sampled and that fits the specimens I have counted from Arizona.
