Plants 20–90 cm. Stems green to reddish-brown when young, branched, glabrous or sparsely hairy (sometimes tomentulose), often gland-dotted (sessile). Leaves ascending to spreading; blades filiform to narrowly oblong (adaxially flat to sulcate), 20–70 × 0.5–4 mm, midnerves evident abaxially, apices acute, sometimes mucronate, faces glabrous or sparsely hairy, often gland-dotted (sessile) and appearing pustular; axillary leaf fascicles sometimes present. Heads in (leafy) racemiform to narrowly paniculiform arrays (2–15 cm). Peduncles 3–15 mm (bracts usually 0). Involucres narrowly campanulate, 8–11 × 7–12 mm. Phyllaries 17–36 in 3–6 series, green to tan, ovate to linear-lanceolate, 3.5–11 × 0.8–2 mm, subequal, herbaceous or herbaceous-tipped, mid and inner chartaceous, midnerves evident at least on distal 1/2, (margins ciliate) apices acute to acuminate or cuspidate, abaxial faces glabrous or hairy, sometimes gland-dotted, resinous. Ray-florets 0–5; laminae elliptic, 8–12 × 1.5–3 mm. Disc-florets 4–14; corollas 7–11 mm. Cypselae tan to reddish-brown, narrowly elliptic, 6–10 mm, glabrous or apically villous; pappi tan to reddish-brown, 6–9 mm. 2n = 18.


Phenology: Flowering summer–fall.
Habitat: Sandy or rocky soils, openings in coniferous woods, Arid Transition and Canadian zones
Elevation: 1000–3000 m

Discussion

Ericameria bloomeri is apparently extirpated in British Columbia. It is widespread, relatively common, and variable. The significance of infraspecific taxa named by H. M. Hall (1928) is largely unexplored.
