Perennials, (30–)50–100 cm; taprooted. Stems persistently grayish tomentose, not glandular, (3–5 mm diam. near bases). Leaf blades narrowly oblanceolate, 2–5(–8) cm × 5–10(–18) mm (gradually smaller distally, becoming lanceolate), bases not clasping, not decurrent, margins flat, faces weakly bicolor, tomentose (adaxial less densely), not glandular. Heads in loose, corymbiform arrays. Involucres turbinate-campanulate, 5–6 mm. Phyllaries in 4–5 series, white (opaque, dull), ovate to oblong-ovate (inner narrower, all usually with filiform but definitely thickened keel and slight apiculum), tomentose (at least bases). Pistillate florets 29–49. Bisexual florets 5–9. Cypselae ridged, smooth to weakly papillate-roughened. 2n = 28.
Phenology: Flowering (Apr–)Jun–Aug(–Nov).
Habitat: Grassy hillsides, gravelly canyon bottoms, chaparral, coastal sage scrub
Elevation: 50–900(–1800) m
Distribution
Calif., Mexico (Baja California).
