Isocoma menziesii var. vernonioides
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.

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.
