Morphology General Habit
Annual or short-lived perennial herb, erect, occasionally slightly woody at base, 0.3–1 m high; stems unbranched or more often branched distally with fastigiate branching, cylindrical, striate, scabrid or pubescent.
Morphology Leaves
Leaves pseudopetiolate (proximal leaves) to sessile (distal leaves), oblanceolate to spatulate, 1–5(–6) cm long, 0.2–1.5(–2) cm wide, base narrow but slightly widening at stem insertion and narrowly truncate to narrowly auriculate, margins entire to denticulate to pinnatilobed with few lobes in the distal half of the leaf with lobes to 12 mm long and 4 mm wide, acute or obtuse and mucronate at apex, scabrid and glandular on both surfaces.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 2–4 mm long, in fairly dense subglobose cymes, the cymes united in terminal, lax, leafy corymbs; stalks of individual capitula 0.1–1 cm, scabrid-pubescent; phyllaries 3–4-seriate, ± 30, the outermost smallest, narrowly lanceolate, 1.5–2.6 mm long, 0.3–0.5 mm wide, entire or serrulate, attenuate at apex, pubescent and glandular on the outermost ones, the inner ones subglabrous and more hyaline; receptacle 1.5–2 mm in diameter, convex to toroid, not toothed.
Morphology Reproductive morphology Flowers Florets
Marginal florets (pale) yellow, 46–60, tube 1.3–1.9 mm long and slightly pilose, mouth oblique and with ?4 small lobes to 0.2 mm, the tube slit on the abaxial side so technically with a ray 0.3–0.5 mm long (but unless the style is projecting through the slit this is very difficult to see), style 2–2.2 mm long; central florets yellow or pale yellow, 2–8, tube 1.4–2 mm long, lobes 0.4–0.5 mm long and often glandular; anthers 0.7–1 mm long with brief triangular appendages; style 2.2–2.5 mm long with short triangular papillose branches.
Morphology Reproductive morphology Fruits
Achenes narrowly obovoid, 0.8–1.2 mm long, ± pubescent and glandular; pappus of many yellowish to pinkish setae, 1.2–2.1 mm long.
Figures
