Leaves imparipinnate, together with rachis 15–26 cm; petiole 4–5 cm; stipules semiorbicular, 1–2 cm in diam., margin coarsely serrate; rachis shallowly sulcate adaxially, initially grayish white tomentose, with few remaining hairs when old; leaflets 5 or 6 pairs, at intervals of 2–3.5 cm, blades dark green adaxially, elliptic, oblong-elliptic, or oblong-lanceolate, 5–9 × 2–3 cm, basal ones smaller, lateral veins 12–16 pairs, arcuate-anastomosing, abaxially prominent and adaxially deeply impressed, abaxially persistently densely grayish white tomentose, adaxially glabrous, base rounded or obliquely cordate, margin sharply minutely serrate, 8–20-toothed per side, entire near base, apex acuminate. Inflorescences 7–12 × 10–18 cm, densely flowered; rachis and pedicels densely grayish white tomentose when young, glabrescent; bracts smaller than stipules. Pedicel 1–3 mm. Hypanthium campanulate, abaxially tomentose. Sepals triangular, 1.5–2.5 mm, sparsely tomentose or glabrous near apex, apex acute or ± obtuse.
