Information
Stems erect, well branched, (0.2)0.4–0.7(1.5) m tall, several from a deep taproot, pubescent to tomentose. Leaves mostly 3-foliolate, but upper ones 1-foliolate and intergrading to bracts; leaflets 3–6.5(9) × 0.8–2.5(3) cm, oblanceolate to elliptic or obovate, apiculate, thinly pubescent to silvery sericeous-tomentose; lower lateral nerves steeply ascending, reticulation rather prominent; petiole 0.5–2.8 cm long; stipules 0.4–1(1.4) cm long, linear-subulate. Flowers yellow, (3)8–30(40) in heads or short dense racemes often aggregated into panicles by suppression of upper leaves; bracts subtending flowers 4–8 mm long, linear or linear-lanceolate; bracteoles on the very short pedicels a little smaller. Calyx 6–10 mm long, tomentose; upper lip c. 1–1.5 times as long as the tube, with the lateral sinuses as high as or higher than the upper sinus; upper lobes 2–4 mm long, narrowly to broadly triangular-acuminate. Standard 8–13 × 3–7 mm, usually elliptic-oblong, pubescent outside. Stamens all joined. Ovary 6–12-ovulate. Pod little exserted from the calyx, 6–8 × 3–4 mm, oblong-ellipsoid, pubescent, usually only 2-seeded. Seeds c. 1 mm long, oblique-cordiform.
