Perennials, 20–50(–60) cm, strongly aromatic (rhizomatous, fibrous-rooted). Stems 3–20, erect, light brown, simple or branched, glabrous. Leaves cauline, dark green; blades lanceolate, 1.5–5 × 1–2.5 cm, 2-pinnatifid (primary lobes 5–9, 0.4–1.5 cm; cauline smaller, pinnatifid to entire), faces tomentose (abaxial) or glabrous (adaxial). Heads (peduncles 0 or to 3 mm) in usually paniculiform, sometimes racemiform, arrays 5–20 × 1.5–4 cm. Involucres campanulate to hemispheric, 2.5–3.5 × 2–4.5 mm. Phyllaries broadly ovate, glandular (at least at bases). Florets: pistillate 3–8; bisexual, sometimes functionally staminate, (15–)20–35; corollas bright yellow, 1.3–2.2 mm, glandular. Cypselae (light brown) ellipsoid (± arcuate, ribs 4, prominent), ca. 1 mm, glandular. 2n = 18.
Phenology: Flowering late summer.
Habitat: Coarse taluses, alkaline soils, erosion gullies
Elevation: 1000–2400 m
Distribution
Idaho, Nev., Oreg.
Discussion
Artemisia packardiae is known only from southeastern Oregon, western Idaho, and northeastern Nevada. It is closely related to A. michauxiana and could be considered an ecologic variant.
