Short-lived stoloniferous perennial herb, erect or often decumbent, 15-50 cm tall; stems slender, weak, unbranched or occasionally branched from the base, glabrous or sparsely pubescent. Leaves linear to narrowly elliptic or oblanceolate, 14-70 x 1-6(-11) mm, densely to sparsely pubescent on both surfaces or ventral surface only, often glabrescent, trichomes eglandular, multicelled, tapering; apex acute or occasionally narrowly rounded; base sessile, broad or tapering; margins entire or rarely denticulate near apices, revolute when dry. Capitula 1-4 in lax terminal corymbs, homogamous, discoid, diameter 5-7 mm (across apices of involucral bracts), peduncles glabrous or very sparsely pubescent, 4.5-80(-135) mm long, with bracts mainly at base of branches, rarely along length. Involucre cylindrical with florets spreading beyond, involucral bracts/phyllaries 8, green tinged purple, tips purple or reddish, 5-8 mm long, with scarious margins, glabrous or sparsely pubescent, mainly near apex. Disc florets purple, mauve, magenta, lilac, pink, (15-)20-33 per capitulum, corolla 5-8 mm long, lobes 1.4-2.3 mm long, glandular at apices, tube 2.8-3.5 mm long. Stamens: anthers 1.9-2.0 mm long with narrow, acute to obtuse appendage (c. 0.25 mm long), sometimes tinged purple, bases minutely sagittate, filament collars slightly balusterform, 0.4-0.7 mm long. Style arms c. 0.6-0.8 mm long, apices shallowly penicillate with short fringing papillae on outer side. Cypselas cylindrical or elliptic due to tapered ends, brown or reddish brown when mature, 1.7-3.1 mm long, glabrous, distinctly ribbed. Pappus 3.5-5 mm long, white, persistent.
