Morphology General Habit
Annual or biennial herb, 0.3-1.5(–2) m high, erect, slightly viscid and aromatic; stems unbranched or sparsely branched in the distal part, pale green, terete, ribbed, white-pubescent to hispid, the long hairs mixed with short glandular hairs.
Morphology Leaves
Leaves sessile (or the proximal pseudopetiolate), very variable in outline, lanceolate, spatulate or oblanceolate, entire to pinnatilobed or pinnatipartite, 2–12 cm long, 0.5–5 cm wide in outline, base semi-amplexicaul, margins dentate with mucronate teeth or lobed to dissected with segments to 3 cm long and entire, dentate or lobed, apex acute or obtuse and mucronate, sparsely to densely hispid to scabrid (mostly on midrib and margins, but to a lesser extent on veins) and with short glandular hairs on both surfaces.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 5–10 mm long, in rather lax leafy corymbs or panicles; stalks of individual capitula 2–17 mm long, densely hairy and glandular; phyllaries ± 40, in several series, pale green with purplish tips, lanceolate, the outermost smallest, 2–8.5 mm long, 0.5–0.6 mm wide, with scarious margins, acute, pilose and glandular; receptacle toroid, alveolar, slightly toothed.
Morphology Reproductive morphology Flowers Florets
Florets pale yellow or cream; marginal florets many (> 100), tube narrowly cylindrical, 1.5–2 mm long, very briefly dentate or fimbriate at the apex (rarely with a brief and narrow ray to 0.8 mm), style 3.5–4.6 mm long; central florets few, tube cylindrical proximally and infundibuliform distally, 2.2–3 mm long, lobes 0.7–1.2 mm and glandular (sometimes also puberulous); anthers 1.1–1.4 mm long; style ± 3.5 mm long with flattened papillose triangular branches 0.3–0.5 mm long.
Morphology Reproductive morphology Fruits
Achenes compressed, obovoid, 1–1.3 mm long, puberulous, ribbed; pappus white or cream with many persistent setae, connate at base, 2.5–6 mm long.
