Characteristics

Scattered to densely leafy dwarf shrub, up to 0.4 m high. Stems woody below, herbaceous upwards, spreading pubescent. Leaves alternate, sessile, linear to very narrowly obovate, 10-23(-30) x 0.5-1.5 mm; apex acute to obtuse; base sometimes slightly broadened; margins entire; spreading pubescent on both sides. Capitula heterogamous, disciform, 8-10 mm in diameter, mostly arranged in loose corymbs or solitary at ends of branches, pedunculate. Peduncle spreading pubescent. Involucre campanulate. Involucral bracts imbricate, in 3 or 4 rows, green, apices sometimes purplish, persistent and recurved in old inflorescences; outer bracts ovate to narrowly oblong, 1.5-2.0 x 0.4-0.5 mm, acute, spreading pubescent; middle row narrowly ovate to narrowly obovate, 2.2-3.0 x 0.5-0.8 mm, acute to acuminate, margin narrowly membranous, slightly fimbriate in upper part, spreading pubescent along central portion; inner row narrowly obovate, 2.8-3.5 x 0.8-1.0 mm, acute, margin narrowly membranous, slightly fimbriate in upper part, glabrous or spreading pubescent along central upper portion. Receptacle epaleate, foveolate. Outer female florets 23-26, arranged in 1 row, fertile, filiform; tube 1.0-1.5 mm long, shorter than style furcation, with glandular hairs, 1-5-toothed; corolla yellow. Style 1.5-2.0 mm long, bifurcate; style branches linear, 0.5-1.0 mm long, rounded to acute; stigmatic areas along margin, confluent at apex. Pappus and cypsela as in disc florets. Disc florets 31-56, regular, bisexual, fertile; tubular below, tube 2.0-2.5 mm long, with glandular hairs, 5-lobed, lobes 0.4-0.5 mm long; corolla yellow, sometimes with purplish apices. Anthers 1.0-1.4 mm long; with ovate apical appendages; base shortly caudate, ecalcarate; filament collars with thickened cell walls. Style 1.5-2.5 mm long, bifurcate; style branches 0.5-1.0 mm long, with deltoid-penicillate apical appendages; stigmatic areas along the margin, not confluent at apex. Cypsela honey-brownish, with faint marginal line, obovoid, 1.0-1.5 x 0.5 mm, shiny because of circular epicarpic cells, covering surfaces of cypselae, each with short twin hair, apices of twin hairs acute but subequal in length. Pappus of caducous, barbellate bristles, 2-3 mm long.
