Annual or biennial herb (perennial fide Drummond & Hemsley), erect, 0.2–3 m tall; stems branched, slightly woody at base, terete, ribbed, glabrous or sparsely pubescent.
Morphology Leaves
Leaves sessile or with a pseudopetiole, membranous, narrowly ovate or narrowly lanceolate, 4–22 cm long, 1–6 cm wide, attenuate at the base but widening at the very base to clasp the stem and sometimes subauriculate, the margins serrulate to serrate with callose teeth or subentire (not in ours), attenuate at the apex, glabrous to sparsely puberulous on both surfaces.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 2–5 mm long, several together in lax half-globose cymes, several to very many cymes combined in large terminal leafy compound panicles or corymbs to 25 cm across, the axes puberulous to glabrous; stalks of individual capitula 2–7 mm long; phyllaries 3–4-seriate, 28–30, pale green, the innermost longest, lanceolate, 1.5–4 mm long, the margins hyaline and serrulate, acuminate to attenuate, glabrous; receptacle flat or toroid, hardly toothed.
Morphology Reproductive morphology Flowers Florets
Marginal florets white, cream or yellow, many, female, tube narrowly cylindric, 0.9–1 mm long, apex minutely toothed, glabrous, style 2–2.5 mm long; central florets white, cream or yellow, fewer than marginal ones, ± 15, tube 1.3–1.7 mm long, lobes 0.5–0.7 mm long, puberulous, anthers 0.8–0.9 mm long; style ± 3 mm long with flattened, lanceolate branches.
Morphology Reproductive morphology Fruits
