Ericameria pinifolia

Plants 50–300 cm. Stems erect to ascending, green when young, fastigiately branched, glabrous, resinous. Leaves ascending to spreading; blades linear to narrowly oblanceolate (terete or adaxially sulcate), 12–35 × 0.5–1.5 mm, midnerves obscure, apices acute, often mucronate, faces glabrous or moderately hairy, gland-dotted (in circular, deep pits), resinous; axillary fascicles of 4–10 leaves, shorter than subtending leaves. Heads in racemiform to thyrsiform-paniculiform arrays (to 30 × 3–12 cm). Peduncles 3–30 mm (leafy). Involucres subcampanulate, 5–8 × 3.5–5.5 mm. Phyllaries 20–26 in 4–6 series, tan, ovate to lanceolate or oblong, 3–7 × 1–1.8 mm, unequal, mostly chartaceous, outermost ± herbaceous-appendaged, midnerves thickened, darker resin ducts, slightly expanded apically, (margins membranous, fimbriate, especially distally) apices erect, acuminate to cuspidate, inner and mid acute to acuminate, abaxial faces usually glabrous, resinous. Ray florets 3–10; laminae 5.5–7 × 1.5–2 mm. Disc florets 11–25; corollas 5–8 mm. Cypselae tan to brown, subobovoid, 3.5–5 mm, glabrous or moderately hairy, more densely distally; pappi off-white to brown, 6–7.5 mm. 2n = 18.

Phenology: Flowering late summer–fall(–spring).
Habitat: Open, sandy to stony soils in chaparral, oak woodland, or scrub in near coastal communities
Elevation: 100–1800 m

Discussion

Of conservation concern.

Ericameria pinifolia ranges from Ventura County to northern Baja California. It blooms primarily in late summer and fall; it sometimes produces scattered, larger flowering heads in spring.
