Characteristics

Shrub 1–5 m. tall, with both normal white hairs and swollen-based hairs on young stems, leaf-rhachides and inflorescences.. Twigs often white.. Leaves normally in tufts; stipules narrow, acuminate, up to 3 mm. long; rhachis 10–40 mm. long, including a petiole of 3–6 mm.; leaflets 7–15, elliptic-oblong, 2–3 times as long as wide, up to 7(–11) mm. long, 2–3.5 mm. wide, shortly mucronate, not revolute at the margin, white pubescent beneath, at least on the midrib and margins but free from swollen-based hairs; midrib, but not the lateral veins, dark beneath.. Racemes 1–3-flowered; rhachis up to 25 mm., pedicels up to 18 mm. long; bracts and bracteoles lanceolate, up to 2 mm. long, the latter up to 3 mm. below the receptacle.. Calyx usually glabrous except at the margin, sometimes sparsely white pubescent but always free from swollen-based hairs which never occur above the bracteoles; receptacle-cup ± 2 mm. deep, 4–5 mm. long and 2–3 mm. wide; tube 3–5 mm. deep; upper lobes obtuse, 3–3.5 mm. long; lateral lobes falcate-triangular, 3–4 mm. long; lower lobe triangular, folded, acute, 4–6 mm. long.. Corolla caducous, cream or bluish, with deep blue-purple mainly longitudinal veins; claw of standard 2.5–3 mm. long, blade ovate, truncate or very broadly cuneate below, 10–14 mm. long, 11–17 mm. wide with 2 large shelf-like protuberances at its base set at 50°–70° to the horizontal, forming an inverted V; claw of wing 3–5 mm. long, blade asymmetrically obovate, auriculate above the base, 11–16 mm. long, 6–7 mm. wide; claw of keel 3–6 mm. long, blade auriculate above at the base, then upper margin straight or concave, 10–13 mm. long, lower margin nearly semicircular.. Stamens (5) + (5), united parts 8–11 mm., free parts 3–6 mm., anthers 1 mm. long.. Disc cylindrical, 0.5 mm. deep.. Ovary straight, 5–8-ovulate, densely covered with appressed swollen-based hairs ± 2 mm. long; stipe glabrous, 2–5 mm. long; style 6–9 mm. long.. Fruit straight or nearly so, up to 50 mm. long, with a stipe of 4–7 mm., densely covered with stiff yellowish swollen-based hairs which may be up to 7 mm. long, not much constricted between the segments which, excluding the bristles, are 8–12 mm. long, 6 mm. wide and 2 mm. thick.. Fig. 52/5, 6, p. 356.
