Leaves 2–7.5 x 0.4–1.5 cm., elliptic to narrowly oblanceolate, tapering into a petiole-like base to c. 2 cm. long, entire or sometimes lobed, apex subobtuse mucronulate, margins ± revolute; upper surface scabrid-hispid, densely beset with conical whitish spinules which grade into scattered conical-based spine-like bristles up to 4 mm. long, the latter usually most numerous towards the leaf base; lower surface whitish or greyish lanate-tomentose except for the mid-nerve.
Involucres 15–30 mm. in diam., the connate part broadly obconic to hemispheric, mostly glabrous; outer phyllaries with free portions 10–20 x 0.5 mm., linear, bristle-Upped, pectinately ciliate on the margins with 10–20 or more bristles 2–3 mm. long on each side; innermost phyllaries with free portions 6–10 x 1–3 mm., narrowly triangular, acute to tapering acuminate, barbellate on the margins, membranous with a narrow dark-purple central part and broad margins.
Disk-floret corollas yellow, c. 8 mm. long, deeply lobed, thinly araneose outside especially on lobes; achenes 4–6 mm. long, narrowly obconic, 10–12-ribbed, glandular, densely long-sericeous; pappus scales 2-seriate, brownish hyaline, the outer ones 5–7 mm. long, oblong-lanceolate, overlapping, the inner ones 2.5–3 mm. long, oblong-ovate, stipitate.
Capitula terminal on branches, sessile and subtended by 3-many leaves which usually exceed the involucre in length.
Branches leafy, hispid, beset with scattered 1–3 mm. long patent whitish bristles.
An erect annual herb, 5–40 cm. tall, branched from near the base.
Rays yellow, 20–25 mm. long, linear-elliptic.
Receptacle shallowly alveolate.
