Leaves 3-foliolate: petiole 1.5-7 cm, pubescent to velutinous; leaflet blades elliptic to obovate, or narrowly so, in terminal leaflet 3.5-16 × 1.3-6.5 cm, pubescent or sparsely so at least abaxially on midvein and secondary veins and adaxially on midvein, apex obtuse to acuminate. Leaves 1-foliolate: petiole 0.8-1.5 cm; leaflet blade elliptic to obovate, 4-9.5 × 2-3.8 cm, otherwise similar to 3-foliolate leaves. Inflorescences axillary and sometimes basal to leaves, 0.8-6 × 0.8-1.7 cm; peduncle 0.1-2.5 cm; larger primary branches spreading or ascending. Pedicel 0.6-2 mm but 2.5-4 mm in fruit, sparsely hispidulous to pubescent. Sepals 1-2 mm, connate at base, outside hirsutulous or sparsely so or rarely nearly glabrous, persistent in fruit. Petals 2-3.5 mm, persistent in fruit. Stamens 4, in male and bisexual flowers 1.5-2.5 mm, in female flowers 1.5-2 mm; filaments at least in male and bisexual flowers narrowly obtuse or sometimes acute at apex. Gynoecium glabrous, in female and bisexual flowers 1-1.5 mm, in male flowers ca. 0.3 mm. Fruit follicles obovoid, 5-8 mm, glabrous. Seeds ovoid, 4-5 mm, attachment Type B. Fr. Aug.
