Phyllaries (ovate, inconspicuous, margins scarious) densely hairy. Florets: pistillate 1–4; functionally staminate 3–6; corollas pale-yellow, 1–1.5 mm, glabrous. Cypselae oblong (distally incurved-falcate and oblique), 0.2–0.5 mm, obscurely nerved, glabrous. 2n = 18.

Discussion

One of the more easily distinguished of the shrubby Artemisia species, A. filifolia occurs in sandy soils and cohabits with species of Yucca, Cactaceae, and Salvia dorrii, the purple sage of western literary fame. Its filiform leaves and faintly aromatic foliage distinguish it from members of subg. Tridentatae.
