Lvs with 2–3–(4) pairs of leaflets; petiole c. 15–40 mm long, glabrous or sometimes with scattered glandular hairs, occasionally with fine eglandular hairs; stipules completely adnate, usually irregularly toothed or lobed, usually glabrous except for some marginal glandular hairs, occasionally with marginal eglandular hairs, sometimes entire with a fringe of numerous glandular hairs. Lamina of leaflets 12–50–(55) × 10–30–(35) mm, elliptic to broadly elliptic, ovate, almost obovate, or orbicular, scarcely to very glossy dark or bright green above and usually glabrous except for a few glandular hairs at base, glabrous or occasionally with dense eglandular hairs on veins on lower surface; margin serrate, at least in upper 1/2, sometimes crenate-serrate; base cuneate to rounded; apex rounded to acute or shortly acuminate. Fls (1)–5- c. 25, in rather loose clusters, single or double, 25–70 mm diam.; pedicels usually with scattered to dense glandular hairs, sometimes with eglandular hairs, occasionally glabrous. Sepals ovate, oblong-ovate or lanceolate-ovate, acuminate or mucronate, tomentose inside, glabrous or puberulent towards the margins and often with glandular hairs outside; outer sepals often with a pair of long lateral lobes.
