Annuals, mostly 10-40(-50) cm; taprooted. Stems erect, sparsely hispido-pilose (hairs spreading, straight, 0.6-2) mm), densely stipitate-glandular. Leaves basal (persistent) and cauline; basal and proximal cauline blades obovate-spatulate, 50-100(-150) × 4-25 mm, cauline gradually reduced (lobing distally), margins pinnatifid or bipinnatifid with (1-)2-4 pairs of rounded to acute lobes, faces sparsely hispido-pilose, stipitate-glandular. Heads 1-5 (peduncles long, ebracteate). Involucres 3-4 × 6-10 mm. Phyllaries in 2-3 series (sometimes basally connate, broad, thin) sparsely hispido-pilose, stipitate glandular. Ray florets 85-110; corollas white, drying dark blue, 6-9 mm, laminae not coiling or reflexing. Disc corollas 1.8-2.9 mm. Cypselae 1.2-1.4 mm, 2-nerved, faces sparsely strigose; pappi: outer of scales (sometimes connate, forming crowns), inner of 11-12 bristles. Flowering (Jan-)Feb-May(-Oct). Stream banks, sandy lake shores, dry washes, desert or riparian scrub, sometime with creosote bush; 300-1200 m; Ariz., Calif., Nev.; Mexico (Sonora). Erigeron lobatus is characterized by persistent basal and proximal cauline leaves with rounded to acute lobes, vestiture of stipitate glands and sparse, spreading, hispido-pilose hairs, heads on relatively long, ebracteate peduncles, and broad, thin phyllaries. Erigeron divergens often is similar; its glandularity is not stipitate and its nonglandular hairs are shorter and denser.

Duration: Biennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous annuals to biennials, 10-50 cm tall, stems several, erect, herbage densely stipitate-glandular, with straight or spreading sparse to dense white hairs, these 0.5-2 mm long, plants taprooted and with woody rhizomes. Leaves: Alternate, with both basal (persistent) and cauline, basal and proximal cauline blades obovate-spatulate, 50-150 mm long and 4-25 mm wide, sometimes with lobed to dentate margins, cauline gradually becoming reduced, linear to oblanceolate and entire or lobing distally, margins pinnatifid or bipinnatifid with 1-4 pairs of rounded to acute lobes, faces sparsely hispido-pilose and stipitate-glandular, blades borne on slender peduncles 3-10 cm long. Flowers: White purple, or lavender, drying dark blue, borne in heads with both ray and disk flowers; ray florets 85-110, with corollas 6-9 mm long, the laminae not coiling or reflexing, disc corollas 2-3 mm long, with turbinate to hemispheric involucres 3-4 mm high and 5-8 mm in diameter, phyllaries narrowly elliptic- to linear-lanceolate, 30-150 in 2-5 series, 1-3-nerved, the nerves golden-resinous and usually flat, rarely broadly keeled to convex, flowers solitary at branch tips or borne in groups of 1-5 (peduncles long, ebracteate). Fruits: Cypselae (achenes) tan, oblong to oblong-obovoid, 1-1.5 mm long, 2-nerved, with sparsely strigose faces. Outer pappus of scales, these sometimes connate, forming crowns, inner pappus of 11-12 bristles. Ecology: Found on stream banks, sandy lake shores, dry washes, plains, mesas, and rocky slopes, in desert or riparian scrub, sometimes with creosote bush, from 1,000-4,000 ft (305-1219 m); flowering January-October. Distribution: Arizona, California, Nevada; Mexico. Ethnobotany: Specific uses for this species are unknown, but other species in the genus have uses; decoction of plant taken for backache, stomachache, menstrual cramps, or used as a contraceptive; salve of toasted, crushed plant and grease rubbed on painful area, and sprinkled on sores, ulcers, cuts and wounds.
