Aleutian wormwood
usually 1–5, turning reddish brown, (often ribbed) tomentose or glabrous.
usually 1, reddish brown to gray, tomentose to glabrate.
persistent or deciduous, mostly basal;
basal blades 4–12 cm;
cauline gradually reduced, 2–4 × 0.5–1.5 cm, 2–3-pinnately lobed, lobes linear to narrowly oblong, apices acute, faces densely to sparsely white-pubescent.
persistent, mostly basal, gray-green; (petioles often expanded) blades (at least proximal) obovate, 1.5–5 × 0.5–1 cm, 2-palmately lobed, lobes relatively narrow, apices acute, faces densely white-villous (brownish in age);
cauline smaller, distally 1-ternate.
broadly turbinate, 2.5–3(–5) × 2–3.5(–7) mm.
hemispheric or globose, (2–)5–7 × (2–)6–8 mm.
pistillate 5–20; functionally staminate 12–30;
corollas pale yellow, sparsely hairy or glabrous.
pistillate 4–6; functionally staminate 15–30;
corollas purplish red, 1.5–2 mm, hairy.
(margins scarious) glabrous or villous-tomentose.
villous.
(pedunculate) in (mostly leafless) paniculiform arrays.
(sessile or peduncles 2–15 mm) in racemiform or spiciform arrays, 1.5–3 × 0.5–1 cm.
oblong-lanceoloid, somewhat compressed, 0.8–1 mm, faintly nerved, glabrous.
oblong, ca. 1 mm, faintly nerved, glabrous.
Artemisia campestris
Artemisia aleutica
Subspecies ca. 7 (3 in the flora).
Artemisia campestris varies; each morphologic form grades into another. The present circumscription is conservative in that only three subspecies are recognized; the subspecies usually can be separated geographically as well as morphologically. Populations in western North America consist primarily of subsp. pacifica; east of the continental divide, plants are assigned to subsp. canadensis in northern latitudes and to subsp. caudata in southern latitudes.

Of conservation concern.
Artemisia aleutica is known only from the western Aleutian Islands. It is morphologically similar to A. borealis, and the relationships of these species complexes warrant further study.
