Leaves 9-15-foliolate, mostly with small, rotund interstitial leaflets, the rachis arching backwards, leaflets to 6 cm long and 1-2 cm broad, narrowly elliptical or lanceolate, apically acute, basally rounded, often oblique, glabrate or with scattered small hairs on the lamina and the midveins puberulent; petiole often bearing interstitial leaflets to the base, the petiolules to 1 cm long or almost wanting. Inflorescence lateral, a few-flowered raceme 4-6 cm long; pedicels filiform, 5-8 mm long, elongating and thickening somewhat in fruit, articulating near the base, glabrous. Flowers small, calyx less than 1.5 mm long, subtruncate with dark, umbonate teeth; corolla white with a dark eye, 1-1.5 cm across, lobed to about the middle; filaments very short.
