Information

Annual (?perennial) herb, erect or procumbent, 4–30 cm high, spreading by underground runners; stems branched, sparsely arachnoid-pubescent to almost glabrous. Leaves alternate, dark green, pinnatisect or bipinnatisect, with dentate lobes, the leaf outline lanceolate, 2–5 cm long, 0.6–2 cm wide, base half-amplexicaul extending into a pseudopetiole up to 2 cm long, with up to 5 lobes on each side as well as a terminal lobe, up to 1 cm long, 0.3 cm wide, the lobes and their teeth apiculate, arachnoid-pubescent when young but glabrescent. Capitula terminal, solitary, 2–5 mm long, ± globose; capitulum stalk 0.6–1.3 cm long, sparsely pubescent; phyllaries 2-seriate, 16–27, obovate, 1–2.5 mm long, 0.5–1.2 mm wide, obtuse or rarely acute, with scarious margins; receptacle flat with remnants of floret stalks. Disc florets many (50+), yellow or pale yellow; the outer in several rows, on up to 0.6 mm long stalks; the inner sessile, corolla ± 1 mm long including 4 lobes to 0.2 mm long, anthers ± 0.3 mm long. Achenes dorsiventrally flattened and slightly concave above, slightly convex beneath, slightly obovoid, 1.2–1.5 mm long, 0.6–1 mm wide, 0.2–0.3 mm thick, with narrow wings widening towards the apex, apex rounded to subcordate, with an unequal-sided mucro up to 0.3 mm long.
