Characteristics

Suberect subshrub with strong taproot; stem partly subterranean, compactly branched, producing annual flowering shoots; branches decumbent, woody at base and closely leafy, becoming pedunculoid and almost naked distally, 150-250 mm tall, sparsely villous with hairs 0.5-0.75 mm long. Leaves patent or suberect, lowermost opposite and decussate with bases connate but soon becoming alternate, rarely subtending dwarf axillary shoots, mostly trifid or subdigitately pinnatisect and then 5-lobed, outline spathulate, 10-14 x 4-6 mm, lobes linear-lanceolate, 3-6 x 0.8-1.0 mm, obtuse, lower leaves and often uppermost becoming progressively oblong-lanceolate, 1.0-1.5 mm wide, leathery, margins strigose with coarse hairs 0.75 mm long and scattered glandular hairs. Capitula homogamous, discoid, solitary, terminal, pedunculate; peduncle sparsely villous but densely villous apically beneath capitula, (40-)60-100 mm long, naked or with one or two linear-lanceolate bracts 6-8 mm long. Involucre broadly hemispherical, 7-8 x 12-15 mm; involucral bracts 4(5)-seriate, lanceolate, thinly hairy or subglabrous, with narrow, scarious, fimbriolate margins, 3-veined, outer bracts 5-6 x 1-2 mm, acute, sparsely or more closely ciliate with hairs ±0.5 mm long, inner bracts 9-10 x 2 mm, acuminate-attenuate, glabrous. Receptacle convex, epaleate, alveolate. Florets bisexual, yellow or apparently reddish at tips, tube cylindrical but widening slightly in upper 2.0-2.5 mm, middle third sparsely pubescent with tapering, eglandular hairs, 4.5-5.0 mm long, 5-lobed; lobes recurved, triangular with thickened margins, ±0.8 x 0.4 mm. Anthers ±2 mm long including ovate, somewhat keeled apical appendage; anther bases obtuse, ecaudate. Ovary obovate, flattened with thickened margins, adpressed-hairy; style terete, branches ±1 mm long, incurved, linear, margins stigmatic, apical appendage triangular, papillate with sweeping hairs at base. Cypsela obovate, ±3.0 x 1.5 mm, flattened with thickened margins, moderately densely adpressed-hairy, with two small apical resin sacs beneath ridges. Pappus biseriate; outer series of minute, obtuse scales united basally in ring; inner series of ±20 bristles, 3-4 mm long, barbellate above but subplumose basally, caducous.
More
Subshrub, up to 250 mm tall. Stems partly subterranean and woody below, producing partly decumbent annual flowering shoots.

Flowerheads discoid, solitary, large; peduncles long, densely hairy apically; disc florets yellow with reddish tips. Cypselas obovate, densely covered with short appressed hairs; pappus of small outer scales united in a ring and barbellate inner bristles, subplumose basally.
