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.
