Morphology General Habit

Woody perennial herb or subshrub or shrub with flexuous stem erect to 2.6 m., or creeping with ascending to erect inflorescences; stem reddish to pale brown, terete (below) to angular, striate, glabrous near base, minutely uncinulate-puberulent and soft spreading pilose with slender tapering hairs above.

Morphology Leaves

Leaves 3-foliolate; stipules lanceolate-ovate to -attenuate, 5–15 mm. long, 2.5–5 mm. wide, striate and puberulent on outer surface, becoming reflexed, deciduous; petioles scarcely to densely uncinulate-puberulent and pilose, the leaf-rhachides usually more densely so than the petioles; leaflets lanceolate or lanceolate-ovate to nearly elliptic, narrowly obovate, or broadly ovate, obtuse to acute or acuminate and mucronulate at apex, obtuse at base, the lateral similar but slightly oblique, essentially glabrous above except along midrib, softly pilose along veins or throughout beneath, the terminal ones 6–17.5 cm. long, 2–6.5 cm. wide, the lateral slightly smaller.

Morphology Reproductive morphology Inflorescences

Inflorescences racemose-paniculate, the racemes lax to very dense; rhachides angular, lineate, reddish to tawny, uncinulate-puberulent to -pubescent with long tapering hairs sparsely or abundantly intermixed; primary bracts each subtending 2 pedicels, ovate- or lanceolate-attenuate, 3–10 mm. long, 0.7–2 mm. wide, essentially glabrous to minutely puberulent on outer surface; secondary bracts each subtending 1 pedicel (± laterally), smaller, similar or scale-like; pedicels uncinulate-puberulent with (or without) long tapering hairs intermixed, becoming reflexed after anthesis, 2.5–6 mm. long.

Morphology Reproductive morphology Flowers

Flowers (said to be inconspicuous) ranging in colour from yellow or pinkish green to vermilion, or cream or white with blue or mauve keel.

Morphology Reproductive morphology Flowers Calyx

Calyx finely puberulent and abundantly long-pilose throughout, the lobes subequal in length, 3.5–4 mm. long.

Morphology Reproductive morphology Flowers Corolla

Standard almost orbicular, retuse at apex, 4–7 mm. long; wings oblong, obtuse at apex, slightly auricled, shortly clawed, 3–6 mm. long, 1.5–2.5 mm. wide; keel-petals equalling standard in length, 1–2 mm. wide.

Morphology Reproductive morphology Fruits

Fruit sessile to shortly stipitate (stipe up to 2.5 mm. long), 2–7-articled, upper suture straight, the lower slightly indented at the isthmi which are 2.5–3 mm. wide; articles minutely uncinulate-puberulent with short fine pilosity intermixed on both surfaces and sutures, 3.5–6.5 mm. long, 2–3.5 mm. wide.

Morphology Reproductive morphology Seeds

Seed ± oblong, brown, 2.3–3.3 mm. long, 1.5 mm. wide.

Morphology General Habit

An erect somewhat woody subshrub 0.9–3.6 m tall.

Morphology Stem

Stems striate or wrinkled, pilose with slightly spreading or appressed hairs together with some very short pubescence.

Morphology Leaves

Leaves 3-foliolate; leaflets 3–17.5 × 1–6.5 cm, oblong-elliptic to ovate-lanceolate or lanceolate, rounded to acute and mucronulate at the apex, rounded or slightly subcordate at the base, glabrous on upper surface except for the midrib, appressed-hairy on the main venation beneath and with sparse to dense shorter hairs between; petiole 0.7–6 cm long, sometimes rather thick and channelled; rhachis 0.6–2 cm long; petiolules 2.5–5 mm long; stipules 7–18 × 2.5–5 mm, ovate-lanceolate, striate, ciliate, persistent.

Morphology Reproductive morphology Inflorescences
