Stems erect to ascending or decumbent; herbage hirtellous or villoso-pilose or densely gray-tomentose (hairs flattened, vitreous, long) to glabrate, sometimes stipitate-glandular. Leaf blades linear to oblanceolate or spatulate-oblong, 10–40 × 2–6(–9) mm, not thick-fleshy, margins of at least the proximal pinnately lobed or shallowly toothed. Heads in corymbiform arrays. Corollas 5–7 mm. Cypselae 2.3–3.6 mm. 2n = 24.
Phenology: Flowering (Apr–)Jul–Dec.
Habitat: Coastal bluffs and dunes, sandy flats, salt marsh borders, occasionally on dry slopes
Elevation: 5–400 m
Distribution
Calif., Mexico (Baja California).
Discussion
Of conservation concern.
In San Diego and Riverside counties, plants of var. vernonioides produce small leaves that are often nearly glabrous, perhaps reflecting the influence of genes from var. menziesii.
