Characteristics

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.. 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.. 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.. Sepals narrowly elliptic, 12.5 mm long, 2 mm wide, with subterminal spine 4 mm long, outside densely stellate-hairy.. 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.. 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.. Fig. 11/10– 11 (p. 71).
More
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.
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.
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.
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.
Fruit up to 3·5 cm. in diam. including the aculei, globose; aculei extremely numerous, densely plumose, with a single fine terminal seta.
Petals yellow, 9–10 mm. long, obovate and narrowed into a linear basal claw which is densely villous just above the base.
Androgynophore very short but with a villous annulus clasping the base of the ovary.
Ovary depressed-globose, villous, 5–6-locular.
Stamens 35–40, 0·8 cm. long.
