erect to ascending, green when young, fastigiately branched, glabrous, resinous.
erect to spreading or recurved, green when young, soon becoming tan to brown, then nearly black when older, highly branched, twigs glabrous, glandular, usually resinous.
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.
ascending to spreading;
blades usually elliptic to oblanceolate, occasionally spatulate, 10–15 × 0.5–1.5 mm, mostly adaxially sulcate, margins entire, midnerves usually obscure to weakly evident, apices acute, apiculate, faces glandular, sometimes irregularly gland-dotted (in shallow pits), resinous;
axillary fascicles present, persistent.
3–30 mm (leafy).

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.
22–30 in 4–5 series, mostly tan, lanceolate to elliptic, 2–6.5 × 0.5–1.2 mm, strongly unequal, outer sometimes herbaceous or herbaceous-tipped (body apices obtuse or truncate to retuse, appendages erect), midnerves not evident or slightly raised, slightly expanded subapically, (mostly margins narrowly membranous, entire) apices acute to acuminate or attenuate, mid often aristate to cuspidate, abaxial faces glabrous, resinous.
in racemiform to thyrsiform-paniculiform arrays (to 30 × 3–12 cm).
in congested, cymiform arrays (0.5–2.5 cm wide).
tan to brown, subobovoid, 3.5–5 mm, glabrous or moderately hairy, more densely distally;

Ericameria pinifolia
Ericameria nana
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.

Some populations of Ericameria nana exhibit extreme variation in leaf shape and in phyllary apex length and shape. Whether such variants represent distinct taxa remains to be tested.
