Morphology General Habit
A shortly trailing, tough-fleshy white-felted sometimes sticky perennial herb with a woody taproot.
Morphology Stem
Stems herbaceous, robust, to c. 1 cm. in diam., prostrate to decumbent, or suberect to c. 30 cm. tall, branched, leafy, producing adventitious roots when buried in sand.
Morphology Leaves
Leaves thick-textured, mostly 6–20 cm. long, usually spathulate, expanded in the apical c. 5 and abruptly narrowed below, sometimes ± lyrate; the apical part 2–7 x 2–7 cm., ± broadly ovate or broadly elliptic, sometimes lobed at the base, apex rounded to obtuse, base rounded-truncate to cordate or broadly cuneate, margins subentire to shallowly dentate with callose-tipped teeth, strongly 5–7-nerved from the base; the lower c. 2/3 to c. 11 mm. wide, linear, sometimes widening into 2-many large lobes towards the apex, widening again near the base and somewhat conduplicate.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula few-many, solitary and terminal on simple or sometimes 1–2-branched axillary stalks up to c. 12 cm. long.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres 1–1.5 cm. in diam., hemispheric; phyllaries from c. 3 mm. long and broadly triangular outside to c. 10 mm. long and lanceolate-ovate inside, all white-felted to lanate on the back apart from scarious tips and margins.
Morphology Reproductive morphology Flowers Receptacle
Receptacle deeply, membranous-walled alveolate.
Ray
Ray-floret corollas yellow, rays 4–14 mm. long, strap-shaped, 3-denticulate apically; ray-floret achenes to c. 3 mm. long, rudimentary.
Morphology Reproductive morphology Flowers Florets
Disk-floret corollas yellow, 3–4 mm. long, funnel-shaped with a short tube and a long campanulate limb with lobes c. 1 mm. long; disk-floret achenes c. 5 mm. long, laterally compressed-turbinate, wider than the corolla, finely lanate; pappus cupuliform consisting of a row of broad partly connate scales 0.5–1 mm. deep, membranous or chartaceous. Ray-floret corollas yellow, rays 4–14 mm. long, strap-shaped, 3-denticulate apically; ray-floret achenes to c. 3 mm. long, rudimentary.
Disc
Disk-floret corollas yellow, 3–4 mm. long, funnel-shaped with a short tube and a long campanulate limb with lobes c. 1 mm. long; disk-floret achenes c. 5 mm. long, laterally compressed-turbinate, wider than the corolla, finely lanate; pappus cupuliform consisting of a row of broad partly connate scales 0.5–1 mm. deep, membranous or chartaceous.
