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. Flowering mid summer. Arctic and alpine tundra and sandy slopes; 0-1000 m; Yukon; Alaska. Artemisia glomerata is similar to A. senjavinensis; it can be distinguished by its more deeply lobed leaves and sparser indument.
