Morphology General Habit
Annual or perennial herb (sometimes called a subshrub) 0.1–1 m high, aromatic; stems much branched, winged, scabrid and glandular or almost glabrous; wings 0.5–2 mm wide, entire or slightly serrate.
Morphology Leaves
Leaves sessile, linear to narrowlylanceolate, 1–7.5 cm long, 0.1–1.4 cm wide, base decurrent into the wings, margins entire or sparsely dentate, apex acute or apiculate, scabrid, glandular and viscid to almost glabrous.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 3–7 mm long, solitary and terminal or 3–6 together in corymbose cymes; stalks of individual capitula 1–6(–15) mm long; phyllaries green and often with purplish tips, lanceolate to linear, 2–5 mm long, 0.6–1 mm wide, margins scarious and ciliate, apex acute to acuminate, scabrid and glandular.
Morphology Reproductive morphology Flowers Florets
Florets mauve or purple, the outer florets stalked with the stalks connate into a rim up to 1 mm long surrounding the unstalked inner florets; outer florets very many, tube 1.5–1.9 mm long; style 2.2–2.6 mm long with filiform branches; inner florets 20–30, tube 1.8–3.3 mm long, slightly widening, distally glandular, lobes 0.3–0.6 mm long and glandular; anthers cream, 1.4–1.5 mm long with ovate distal appendages; style long-exserted, purplish, 3.5–6 mm long, minutely bifurcate with closely parallel branches.
Morphology Reproductive morphology Fruits
Achenes cylindrical, 0.3–0.4 mm long, vestigial in inner florets; pappus absent in outer florets.
