Plants 10–30 cm. Stems erect to ascending, green when young, soon reddish to brownish, branched, glabrous or tomentose, stipitate-glandular. Leaves mostly erect or ascending; blades spatulate (flat), 15–30 × 3–7 mm, midnerves (and sometimes 2 fainter, collateral nerves) evident (slightly raised abaxially), apices obtuse, mucronate, faces glabrous or tomentose and/or stipitate-glandular; axillary fascicles absent. Heads (12–22) usually in (leafy) congested, cymiform or racemiform arrays, rarely borne singly. Peduncles usually less than 20, rarely to 100 mm (leafy). Involucres broadly campanulate, 8–12 × 12–15 mm. Phyllaries 18–28 in 2–3 series, green to tan, lanceolate to elliptic, 10–14 × 1.3–2.7 mm, subequal (outer sometimes slightly longer than inner), outer herbaceous or with herbaceous appendages, inner mostly chartaceous, midnerves (and often 2 collateral nerves) evident, (margins often narrowly membranous, fimbriate or tomentose) apices acute, acuminate to cuspidate, abaxial faces stipitate-glandular. Ray florets (0–)1–7; laminae 7–10 × 1.5–2.8 mm. Disc florets 7–20; corollas 8–9.5 mm. Cypselae tan to reddish, ellipsoid, 5–7 mm, glabrous or distally hairy; pappi off-white to reddish brown, 7–9 mm. 2n = 18.

Phenology: Flowering summer–fall.
Habitat: Rocky flats and sparsely wooded slopes
Elevation: 1500–2200 m



Calif., Idaho, Oreg., Wash.


A tomentose entity that was recognized as Haplopappus greenei subsp. mollis differs also in other ways from typical Ericameria greenei. It may merit recognition at some level. A biosystematic and population-level investigation of this complex is needed to better understand the causes and significance of such variation.
