| Description: | A small, spreading annual or short-lived perennial herb, to 150(-200) mm tall, mostly delicate or sometimes more vigorous and branching mainly from the base, tomentose to almost hairless, glandular. Leaves laxly or densely set, sometimes almost crowded on short, brachyblasts present but mostly with leaves shorter than the subtending leaf, linear, 2-25 x 0.5-2 mm, greyish-tomentose to green and glabrescent, ventrally furrowed and somewhat tomentose, densely glandular. Capitula solitary, radiate, florets yellow. Peduncles smooth, wiry, 10-60 mm long, often at an angle to the main branch and the tip turned upwards. Involucre cup- to bell-shaped, 4-12(-15) mm wide. Involucral bracts 15-50, smooth, acute-obtuse; outer small and ovate; inner gradually longer and oblong with a scarious and often brown apical limb, 5-9 x 0.7-1.6 mm. Receptacle flat-convex, scabrid with small projections and furnished with a distal row of acute or apically laciniate, 0.8-4 mm long, persistent scales. Ray florets 8-35; tube glabrous or with scattered, multicellular hairs; lamina elliptic, 2-9 x 0.7-3 mm; cypselas 2.5-3.8 mm long, with twin hairs and often with a basal tuft of similar hairs, remaining clasped between the spreading receptacular scales and the innermost involucral bracts; pappus of short, flat, obtuse-truncate, white scales but with no bristles. Disc florets 20-175, perfect; corolla 2.6-4 mm long; tube with scattered, multicellular hairs and often with a collar of similar, densely set hairs just below the limb. Cypselas 2.5-3.8 mm long, glabrous or with few twin hairs and often with a basal tuft of similar hairs; pappus of short, flat, obtuse-truncate, white scales and 2-5 outer, basally barbellate and only apically plumose bristles.
