Petioles and rachises sericeous,pedicels glabrous.Standard:blade 6–10 by 4–9 mm. Wings sculptured. Ovary with bulbous-based hairs. — Type: Milne 108 (holo K!), Fiji.

Treelets or shrubs. Twigs terete, 4–5 mm diam, glabrous. Stipules triangular, 2–4 by 1.2–1.7 mm, both sides glabrous. Leaves with 7–15 leaflets. Petiole 3– 6 mm long, sericeous, with bulbous-based hairs; rachis mostly as the petiole, 10–23 mm long; pulvinus c. 1 mm long. Leaflets: terminal one (broadly) obovate, 4–8 by 2–5 mm, 1.1–2.1 times as long as wide, base cuneate to acute, apex acute to retuse, apiculate, upper surface glabrous, lower surface with few hairs, midrib and nerves flat above, nerves ± black, 2–5 per side, 1–1.3 mm apart; lateral leaflets mostly as the terminal one, obovate to elliptic, 3.5–8 by 1.6–5.5 mm, 1.2–2.1 times as long as wide, nerves 4–6 per side, 1–1.6 mm apart, venation brownish, ± similar to (slightly) darker than the rest of the surface; pulvinus 0.3–0.6 mm long. Bracts to the flowers broadly obovate, 0.7–2.3 by 0.5–2 mm, outside glabrous, inside glabrous or with few hairs at the base. Pedicels 4.4–8 mm long, glabrous. Bracteoles circular to elliptic, 0.7–2.9 by 0.6–1.2 mm, both sides glabrous. Calyx 5 –7 mm long, tube 4–5.5 mm long; teeth of upper lip triangu- lar, 0.4–1.5 by 0.7–2 mm; lateral teeth triangular, 1.5–2 by 1.5–2 mm, median tooth triangular, 1.6–3 by 1.1–2 mm; both sides glabrous, teeth ciliate. Standard: claw 1.5–3 mm long; blade broadly obovate to orbicular, 6–10 by 4–9 mm, apex rounded or emarginate, with 1 or 2 basal callosities, both sides glabrous, apex ciliate. Wings: claw 2–2.5 mm long; blade obliquely obovate to ‘boat-shaped’, 5–10 by 4–5 mm, auricles 0.2–0.8 mm long, outside sculptured along upper margin in basal part, both sides glabrous, apex ciliate. Keel petals: claw 2.2–4 mm long; blade ‘boat-shaped’, 5–8 by 4.2–5.2 mm, auricles 0.4–0.6 mm long, both sides glabrous. Stamens all in an open sheet, in upper part split into two bundles of 5 each, tube 3.8–8 mm long, free part 1.5–6 mm long, glabrous; anthers 0.4–0.9 by 0.2–0.5 mm, glabrous. Disc 0.5–0.6 mm long, glabrous. Ovary 3– 6 mm long, with bulbous-based hairs; stipe 2.5–4 mm long, glabrous or with bulbous-based hairs; ovules 2–4; style 4–6.5 mm long, glabrous. Pods (young) strap-like, beak c. 5 mm long, articles flattened ellipsoid, 12–13 by c. 6 mm, with bulbous-based hairs. Seeds flattened ellipsoid, c. 6 by 3.5 by 0.2 mm; hilum c. 1.8 mm long.

Distribution — Fiji, New Caledonia

Habitat & Ecology — Dry terrain, dry rocks, waste places.

Note — The specimen Vieillard 398b [P00440555] with rounded, retuse and acute young leaflets probably belongs here.
