Treatment appears in FNA Volume 19. Treatment on page 511.
Leaves broadly cuneate (lobed, lobes less than 1/2 blade lengths, 1–3 mm wide, rounded). Involucres 3.5–4 (–5) × 2–4.5 mm. 2n = 18, 36.
Phenology: Flowering mid–late summer.
Habitat: Rocky sedimentary soils, high valleys, mountain slopes

Distribution
Calif., Colo., Idaho, Mont., Nev., Utah, Wash., Wyo.
Discussion
The relatively large heads of Artemisia arbuscula subsp. arbuscula suggest a relationship with A. cana; the extreme morphologic variability of this subspecies from east to west may be the result of hybridization with various subspecies within the A. cana complex.
