Robust herb, subwoody at base; stems decumbent, up to 3 dm. × 5 mm., ascending at tips; branches ∞, at first clad in soft pubescence. Lvs alt., bases persistent; lamina (15)-20-35-(50) × (6)-8-10-(12) mm., almost sessile; obovate- to oblong-cuneate or spathulate, 3-toothed to entire at apex; fleshy, margins ± cartilaginous; densely clad in fine soft pubescence above and below. Scapes axillary and terminal, densely glandular-hairy, 12-25 mm. long, stout, pilose; capitula (5)-8-10 mm. diam.; phyll. 10-15 in c. 2 series, outer ovate-lanceolate, inner broad-oblong, thinly hairy on outer surfaces. Florets yellow, eglandular; ♀ ∞, pedicellate, corolla minute, pale yellow, indistinctly toothed; ♂ ∞, tubular, 4-toothed. Achenes compressed obovoid-cylindric, slightly to densely glandular, strongly ribbed, 1-2 × 0·5 mm.
Cotula featherstonii (F.Muell.) Hook.f.
A robust, luxuriant suberect perennial herb. Stems erect or later becoming decumbent, 0.2-1.2 m tall, thick, up to 6 mm diam., green, hard, subwoody at base, incompletely ringed at intervals with old leafscars and sparsely covered with short deciduous hairs; branches clustered, us. 3-4 diverging from a flowering node and the nodes immediately behind, often repeated at later nodes several times per season; leaves several clustered at the apex, older ones scattered 0.2- 3.0 cm apart. Roots not seen. Leaves simple, almost sessile, 1.5-4.0 × 0.7-1.7 cm; blade obovate, narrowing into ill-defined petiole and leafbase, tender, grass-green, glabrous to thickly and evenly covered with soft, suberect, zh deciduous hairs, midrib and principal veins evident on both surfaces, with 0-3 shallow triangular obtuse teeth on either side just below the apex. Peduncles shorter than leaves, 1-2 cm, with 0 or a few small bracts, villous. Monoecious. Heads ca. 1 cm diam.; surface hemispherical; involucre hemispherical; phyllaries 10- 15 in 1-2 subequal rows, broadly elliptic, rather thick, green with 1-3 brown veins evident, sparsely pilose, with a narrow transparent scarious margin around the apex only, not growing after anthesis; pistillate florets ca. 200 in 6 or more rows, ca. 2.0 mm long, almost straight, yellow-green; corolla ca. 3 times as long as wide, blunt, with equal teeth; staminate florets fewer, ca. 130. Achenes up to 1.5 × 0.7 mm, slightly compressed, chocolate-brown, striated with 2 lateral, 2-4 anterior and 2-4 posterior pale ribs, unwrinkled. Probably flowers from spring to autumn.
