Morphology General Habit
Woody shrub (0.6–)0.9(–1.2) m tall, with ascending, blackish brown, sometimes very hairy branches to 5 mm thick from a single stem.
Morphology Leaves
Leaves pedate or deeply pedatifid, usually completely divided, with (3–)5 leaflets, uppermost leaves often only deeply trifid, 2–8 cm long, 3–14.5 cm wide; leaflets sessile, narrowly elliptic-lanceolate to linear, 1.7–7 cm long, 0.5–1.3 cm wide, acute, cuneate, sessile, margin serrate, teeth up to 2 mm long, with secondary and tertiary veins prominent above, dirty white beneath, grey-brown stellate-scabrid on both surfaces, more densely so beneath; petiole 1–4 cm long, terete, dull grey-brown densely stellate-hairy; stipules linear-lanceolate, 10–12 mm long, 2–3 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescences terminal, congested, hairy; peduncles 2–7-flowered, branching 2–3 times, opposite a narrowly ovate reduced leaf 6–9 mm long, 2–4 mm wide; bracts slightly smaller than the reduced leaves; pedicels ± 1 mm long.
Morphology Reproductive morphology Flowers Calyx
Sepals narrowly elliptic, 12.5 mm long, 2 mm wide, with subterminal spine 4 mm long, outside densely stellate-hairy.
Morphology Reproductive morphology Flowers Corolla
Petals spathulate, the blade rounded, 5 mm long, 5.5 mm wide, upper margin sinuate; claw 9 mm long, ± 1 mm wide, with a narrow, densely hairy band on the inner surface ± 1 mm from the base; stamens 40–60; ovary densely villose, hairs 1 mm long.
Morphology Reproductive morphology Fruits
Fruit oblate, indehiscent, 10–11 mm long, 15–18 mm wide, completely covered by more than 100 weak bristles ± 1.5 mm long, each bristle densely covered by interlocking reddish hairs in the lower part.

Morphology General Habit
Low shrub about 0·6 m. tall or sometimes with the branches trailing and almost prostrate, branching mostly from the base; branches densely ferruginously stellate-hairy when young.
Morphology Leaves
Leaf-lamina 1·5–5 × 0·7–1·4 cm., deeply 5–7-partite or -digitate; segments or leaflets oblanceolate, with appressed-stellate hairs of two kinds, some small and some much larger above, whitish- or pale-brownish-tomentellous below, acute or subacute at the apex, margin serrate, cuneate at the base; petiole up to 2·5 cm. long, ferruginously hairy.
Morphology Reproductive morphology Inflorescences
Inflorescences ferruginous, of rather dense cymes opposite the bracts ± aggregated into small terminal panicles; bracts similar to the leaves but smaller and often displaced upwards so that the inflorescences appear axillary; peduncles up to 2·5 cm. long, ferruginous; pedicels up to 5 mm. long but usually less, ferruginous and bearing linear ferruginously hairy bracteoles up to 8 mm. long.
Morphology Reproductive morphology Flowers Calyx
Sepals 12–14 mm. long, linear, narrowing to the apex, ferruginously stellate-hairy outside, with a horn 4–5 mm. long inserted 0·75–1 mm. below the apex.
Morphology Reproductive morphology Flowers Corolla
Petals yellow, 9–10 mm. long, obovate and narrowed into a linear basal claw which is densely villous just above the base.
Morphology Reproductive morphology Flowers Androgynophore
Androgynophore very short but with a villous annulus clasping the base of the ovary.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 35–40, 0·8 cm. long.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary depressed-globose, villous, 5–6-locular.
Morphology Reproductive morphology Fruits
Fruit up to 3·5 cm. in diam. including the aculei, globose; aculei extremely numerous, densely plumose, with a single fine terminal seta.
