Artemisia glomerata

Perennials, 30–50(–100) cm (densely cespitose), mildly aromatic (not rhizomatous, caudices subterranean, branches clothed with persistent leaf bases). Stems relatively numerous, ascending, brown, simple, hairy. Leaves mostly basal (cauline mostly 2–4, smaller), whitish; blades (basal) flabellate, 0.5–1(–2) × 0.5–0.8(–1.5) cm, relatively deeply lobed (lobes 5–9, linear), faces strigillose. Heads (3–10, erect or nodding, peduncles 0 or to 15 mm) in subcapitate to corymbiform arrays 1–5 × 2–4 cm. Involucres broadly campanulate, 3–4 × 3.5–5 mm. Phyllaries lanceolate (margins brownish), densely pilose. Florets: pistillate 4–5; bisexual 10–15; corollas yellow (3–5-toothed), 2–2.5 mm, glabrous or sparsely pilose. Cypselae ellipsoid (flattened, margins ribbed), 1–1.5 mm, glabrous. 2n = 18, 27, 36, 54.

Phenology: Flowering mid summer.
Habitat: Arctic and alpine tundra and sandy slopes
Elevation: 0–1000 m

Discussion

Artemisia glomerata is similar to A. senjavinensis; it can be distinguished by its more deeply lobed leaves and sparser indument.
