5. Artemisia carruthii A.W. Wood ex Carruth.

Pl. 226 e, f; Map 945

Plants perennial herbs, with long-creeping rhizomes, sometimes producing short vegetative stems among the taller flowering ones, strongly aromatic when bruised. Stems 10–60 cm long, erect or ascending from sometimes spreading bases, densely pubescent with grayish white, woolly or felty hairs, these hiding the minute glands. Leaves 0.5–2.5(–5.0) cm long, relatively long-petiolate to sessile, often with a pair of slender, stipulelike lobes or leaflets at the base. Leaf blades mostly 1 time pinnately compound or deeply lobed, narrowly oblanceolate to oblong-ovate or obovate in outline, the main leaves with 3–5(–7) lobes, the ultimate segments or lobes 0.5–2.0 mm wide, narrowly linear and often threadlike, mostly sharply pointed at the tip, the margins entire and usually rolled under, both surfaces densely pubescent with woolly or felty hairs, the upper surface sometimes glabrous or nearly so, also minutely glandular. Inflorescences appearing paniculate, ranging from narrow and spikelike with short, densely flowered branches to more open with longer, ascending branches, the heads sessile and/or very short-stalked. Heads with the central florets perfect and the marginal florets usually pistillate, thus all of the florets potentially producing fruits. Involucre 2.5–4.0 mm long, the bracts in 2 or 3 overlapping rows, the often indistinct main body linear to oblong-elliptic, moderately to densely woolly-hairy and minutely glandular, with broad, thin, transparent margins and tip, these usually glabrous but sometimes appearing cobwebby-hairy. Receptacle naked, without bristly hairs. Corollas 1.3–2.0 mm long. Fruits 0.7–1.0 mm long, narrowly ellipsoid-obovoid to nearly cylindrical, faintly lined, somewhat flattened, reddish brown to brown, shiny. 2n=18. August–October.

Introduced, uncommon, known only from historical collections from Jackson County (native from Nevada to Kansas south to Arizona and Texas; Mexico; introduced eastward to New York). Railroads and open, disturbed areas.
