Morphology General Habit
Diffuse ± glaucous herb with horizontal stems or prostrate, up to 1 m long, with sparse white ± stiff hairs 0.5–1 mm long, from thickened bases but otherwise glabrous; older stems minutely tuberculate where hairs have broken off.
Morphology Leaves
Leaves (6)10–14-foliolate; leaflets glaucous, (5)7–14 × 2–7 mm, oblong, rounded to truncate at the apex and when young with fine white hair terminating the mucro soon breaking off, bleakly rounded at the base, glabrous, 5–7-nerved from the base including the distinctly eccentric main nerve; petiole and rhachis together 1.5–5.3 cm long, with sparse bristly hairs; stipules 3–7 × 0.8–2.5 mm, ovate-lanceolate to lanceolate, 7–13-nerved, not appendaged.
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, 1.5–2.5(4) cm long; peduncles up 1.5 cm long; pedicels 2.5–4 mm long; bracts 3–5 × 1.1–1.5(2) mm long, lanceolate, persistent, 7-nerved, with marginal bristle-like hairs; bracteoles 3 × 0.5–0.8 mm, narrowly lanceolate, sparsely white bristly ciliate.
Morphology Reproductive morphology Flowers Calyx
Calyx lobed, the upper 3–4 × 2 mm, entire, the lower 4.2–5 × 2 mm, 3-lobed.
Morphology Reproductive morphology Flowers Corolla
