Morphology General Habit
Perennial herb, woody herb or shrub, 0.4–2 m high; stems wiry, distally branched, with dense leaf scars and some marcescent leaves, scabridulous but glabrescent.
Morphology Leaves
Leaves sessile, linear to lanceolate, 0.8–5(–7) cm long, 0.1–1.4 cm wide, base ± auriculate, margins entire to dentate with callose teeth, often inrolled, apex acute and mucronate, scabrid above, scabrid on midrib and veins beneath and arachnoid-pubescent or rarely glabrous in between, often glandular.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 4–6 mm long, several together in slightly lax hemispherical cymes, several of these united into a terminal, lax, leafy corymb; stalks of individual capitula 2–7 mm long, pubescent and often glandular; phyllaries 3–4-seriate, ± 24, pale green, the outermost shorter than the inner, lanceolate, 2–4 mm long, 0.5–0.9 mm wide, margins hyaline and often fimbriate, apex often reddish, acute and fimbriate, the outermost pubescent, the inner more glabrous; receptacle flat to convex, toothed.
