Leaf-rhachis commonly ± 2 mm., much less than half as long as basal leaflets; leaflets cuneate-oblanceolate, usually 2·5–4 times as long as wide, commonly ± 12 mm. by 4·5 mm., appressed pubescent on both sides; basal leaflets usually much the same shape and size as the others but sometimes asymmetrically oblong.. Umbels 2–7-flowered; peduncle 2–5 cm. long, appressed pubescent, densely so towards the top; bract 1–3-foliolate, oblanceolate; glands obscure, minute; pedicels densely appressed pubescent, ± 3 mm. long.. Calyx appressed pubescent, the tube ± 3 mm. long, 1 mm. below and 2 mm. above the insertion of the stamens; teeth triangular-acuminate, ± 3 mm. long.. Corolla white with pink markings; standard cuneate-oblong, constricted above the middle, 6–9 mm. long, 1–2 mm. shorter than the wing.. Filament-sheath 4–6 mm. long, the free parts of the shorter filaments two-thirds or three-fourths as long as those of the longer filaments.. Ovary 4–5 mm. long, ± 25-ovulate; style 3–5 mm. long.. Pod ± 2·5 cm. long, ± 8-seeded.. Fig. 146/14, p. 1046.
Perennial herb, erect 0.3-0.9 m high; many herbaceous stems from a woody rootstock, sometimes scrambling, yellowish green when dry; indumentum variable, from appressed-pubescent to pilose. Leaves 5-foliolate; leaf rachis shorter than half the length of basal leaflets. Leaflets: basal ones oblanceolate, apical leaflets cuneate-oblanceolate to cuneate-obovate, apiculate at apex; both surfaces sparsely appressed-pubescent or spreading hairy, with conspicuous brown dots, especially on lower surface. Inflorescences (2)5-or 6(8)-flowered umbels; peduncle 20-90 mm long. Calyx light green, purple-tinged, appressed or spreading hairy; hypanthium ± 1 mm long, tube above insertion of stamens 2.0-2.5 mm long; teeth triangular-acuminate, 1.5-3.0 mm long. Flowering time Aug.-Jan.
Leaves usually well spaced, often remote towards the base, 5-foliolate; leaf rhachis usually 1.5–4.5 mm long, less often up to 6(10) mm long, usually shorter than half the length of the basal leaflets or sometimes longer, indumentum as for the stems; basal leaflets 5–15 × 2.2–7 mm, 2–3 times as long as wide, oblanceolate to obovate, similar to the apical ones but smaller, or sometimes asymmetrically elliptic-oblong, subacute to rounded but apiculate at the apex, cuneate to obtuse at the base; apical leaflets 10–18 × 3–7 mm, 2.5–4 times as long as wide, cuneate-oblanceolate to cuneate-obovate, acute to rounded but apiculate at the apex; all leaflets appressed pubescent or spreading hairy on both surfaces, sometimes sparsely so; stipular glands very small or absent.
Corolla white or cream, the standard sometimes veined with purple, the keel with purple tip; standard 7–9 × 3.5–4.5 mm, usually 0.5–1.5 mm shorter than the wings, ± violin-shaped, wedge-shaped at the base, retuse, the margins infolded over 4–5 mm from the base, the upper third wider and abruptly bent upward; wings 9–11 mm long including the 3–3.5 mm long claw, the blade c. 4 mm wide, oblong, laterally pouched, strongly auriculate; keel c. 1 mm shorter than the wings, curved, pointed, the claws c. 3 mm long.
Stems erect and 30–90 cm tall, or sometimes scrambling and up to 2 m long, usually up to 2.5 mm in diameter, the epidermis yellowish-green when dry, whitish or yellowish appressed pubescent, sometimes sparsely so, or pilose with spreading and arching or curled whitish or yellowish hairs, grooved, sometimes the prostrate stems woody and persisting, tinged purple.
Umbels 2–8-flowered, usually 5–6-flowered; peduncle 2–9 cm long, occasionally up to 15 cm long; foliage leaf on the peduncle sometimes inserted up to 5(8) mm above the tip, 1-foliolate or 3-foliolate with leaflets up to 14 mm long but often much shorter, oblanceolate; pedicels 1.5–3 mm long; glands (bracts) minute or absent.
Calyx light green often purple-tinged, appressed pubescent or spreading hairy; hypanthium c. 1 mm long, calyx tube 2–2.5 mm above the insertion of the stamens; calyx teeth 1.5–3 mm long, triangular-acuminate.
Filament sheath 5–6 mm long, papillose near the base; free parts of the shorter filaments c. 2 mm long, those of the longer filaments c. 3 mm long.
Ovary 5–6 mm long, glabrous, 25–29-ovulate; style 3–4 mm long, curved upwards.
Pod up to 35 × 3 mm, often much shorter, reddish-brown to greyish-brown.
