Morphology General Habit

Perennial with scandent to procumbent stems rooting at the lower nodes and forming shoots to 1 m. or more long; stems subangular to cylindric, usually densely spreading pilose and somewhat puberulent.

Morphology Leaves

Leaves 3-foliolate; stipules obliquely ovate-attenuate, 3.5–8.5 mm. long, ± puberulent on the outer surface; stipels slender and persistent, 0.5–4 mm. long; petiole stramineous to reddish, densely long-pilose, 7–19 mm. long; leaf-rhachis similar, 3–12 mm. long; terminal leaflets suborbicular to elliptic or obovate, retuse and rounded to truncate at apex, cuneate to rounded at base, 1.4– 4.2 cm. long, 1–2 cm. wide, lateral leaflets similar or more nearly elliptic, 1–3 cm. long and 0.7–1.5 cm. wide, all glabrous to moderately pilose above, rather densely pilose beneath.

Morphology Reproductive morphology Inflorescences

Inflorescence of axillary and terminal panicles or racemes; rhachides densely uncinulate-puberulent, sometimes also sparsely to moderately spreading or appressed pilose; primary bracts each subtending 2 pedicels, ovate-attenuate, 2.3–6.5 mm. long (the attenuate tip 1.5–2 mm. long), 1.5–2 mm. wide, somewhat pilose on the outer surface; secondary bracts occasionally present, rather depauperate, 1.3–2 mm. long, 0.5–1.5 mm. wide, rarely a minute bracteole is borne on the pedicel; pedicels uncinulate puberulent, 4–13 mm. long.

Morphology Reproductive morphology Flowers

Flowers white, yellow, or mauve turning blue (or, fide Milne-Redhead & Taylor 9733, the standard mauve, the wings deep violet above and white below, the keel white).

Morphology Reproductive morphology Flowers Calyx

Calyx 2-lipped, green, minutely puberulent throughout, long-pilose especially on the teeth of both lobes; teeth subequal, 2–3.5 mm. long; standard obovate, retuse, equalling or exceeded by the keel, 2.5–4.5 mm. long, 4 mm. wide; wings slightly shorter, 3mm. long, 1 mm. wide.

Morphology Reproductive morphology Fruits

Fruit sessile to shortly stipitate or the basal 1 or 2 articles aborted, up to 6-articled, the upper suture slightly, the lower rather deeply indented at the isthmi; articles obtusely curved below, 1.5–3 mm. long, 1.5–2 mm. wide, uncinulate-puberulent throughout to glabrescent; style usually persistent, rather twisted.

Morphology Reproductive morphology Seeds

Seed obtusely oblong or subreniform, 1.5–2 mm. long, 1–1.5 mm. wide.

Morphology General Habit

Prostrate or trailing perennial herb 0.5–1 m long.

Morphology Stem

Stems mostly several from a somewhat woody base, sometimes rooting at the nodes, densely covered with whitish, ferruginous or yellowish spreading or more rarely appressed hairs.

Morphology Leaves

Leaves 3-foliolate, leaflets 5–35 × 4–30 mm, the laterals usually distinctly smaller, mostly obovate or rounded to elliptic, truncate, rounded or slightly emarginate at the apex, cuneate or rounded at the base, glabrescent or sparsely pilose above, densely appressed pilose beneath; petiole 0.5–3 cm long, densely pilose; rhachis 2.5–7 mm long; petiolules 1–2.5 mm long; stipules 5–10 × 1.5–2(2.5) mm, lanceolate, brown, striate, hairy, persistent.

Morphology Reproductive morphology Inflorescences

Inflorescences terminal and axillary, 2–7(25) cm long, uncinulate-pubescent and with longer appressed hairs; peduncles 1–3 cm long; pedicels 5–14 mm long, puberulous; primary bracts each supporting 2 pedicels, 2.5–6 × 1.5–2 mm, ovate-lanceolate, hairy; secondary bracts usually absent.

Morphology Reproductive morphology Flowers Calyx

Calyx with spreading bristly hairs; tube 1 mm long; lobes 1–1.5 mm long, narrowly triangular.

Morphology Reproductive morphology Flowers Corolla

Standard white, yellow, pale mauve, pink or purple turning blue on drying, c. 4 mm long and wide, broadly obovate, emarginate; wings and keel purple at apex.

Morphology Reproductive morphology Fruits

Fruit 5–15 mm long, of 1–6 articles, separating and not dehiscing as in previous species; articles with the upper margin slightly curved and lower margin strongly curved, 2–3 × l.6–2.2 mm, glabrescent or uncinulate-pubescent, joined by necks 0.5–1.5 mm wide, reticulately veined.
