Ericameria bloomeri (A. Gray) Macbr.

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.

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.

Ericameria bloomeri, known by the common names Bloomer's rabbitbush and Bloomer's goldenbush, is a species of flowering shrub in the family Asteraceae. This plant is native to the mountains of western North America from British Columbia to California, including Washington, Oregon, Idaho, and Nevada. It may have been extirpated from Canada.

Ericameria bloomeri grows in coniferous forests. This is a small shrub reaching a maximum height of about 50 centimeters (20 inches) and covered in a foliage of threadlike to slightly oval leaves a few centimeters long. It may be glandular and resinous and slightly woolly or hairless. Atop each of the many erect branches is an inflorescence of golden yellow flower heads. Each centimeter-wide head has up to 14 disc florets and sometimes up to 5 ray florets but sometimes none. The dense inflorescence has resin glands and some woolly fibers.
