Subalpine Goldenbush

Ericameria zionis is known from southern Utah.

Plants 10–30 cm. Stems decumbent to ascending, green when young, often reddish tinged, soon reddish brown to brown, branched, twigs long-stipitate-glandular (sometimes with crinkly hairs interspersed). Leaves mostly erect or ascending; blades spatulate (flat), 25–40 × 2.5–7 mm, midnerves (plus 2 smaller, collateral nerves) evident, apices acuminate, faces long-stipitate-glandular; fascicles absent. Heads in (leafy) congested, paniculiform to cymiform arrays (1–4 cm wide). Peduncles 3–15 mm (long-stipitate-glandular, bracts 0–3, phyllary-like). Involucres turbinate to narrowly campanulate, 14–22 × 6–8 mm. Phyllaries 17–23 in 2–4 series, tan to green, lanceolate to elliptic, 10–14 × 1.6–2.7 mm, subequal (outer often slightly longer than inner), outer herbaceous or with herbaceous cusps, inner mostly chartaceous, midnerves (often plus 2 collateral nerves) evident, (margins villous distally) apices acute to acuminate, abaxial faces stipitate-glandular, inner sometimes glabrous. Ray florets 0. Disc florets 10–21; corollas 9.5–12 mm. Cypselae tan to reddish, ellipsoid, 7–8 mm, glabrous or apically hairy; pappi off-white to brown, sometimes reddish, 9–9.5 mm. 2n = 18 [as Haplopappus bloomeri subsp. compactus].

Ericameria zionis, the subalpine goldenbush or cedar breaks goldenbush, is a rare North American species of flowering plants in the family Asteraceae. It has been found only at high elevations in the mountains in the southern part of the state of Utah in the western United States. Some of the populations lie inside Cedar Breaks National Monument and Bryce Canyon National Park.

Ericameria zionis is a branching shrub up to 30 cm (12 inches) tall. Leaves are spatula-shaped, up to 40 mm (1.6 inches) long. One plant can produce many small white flower heads in a tightly packed clump, each head with as many as 21 disc florets but no ray florets.
