Leaves narrowly to broadly ovate, 4-13 × 2.3-11 cm, base broadly cuneate to broadly rounded or truncate or more commonly cordate, margin denticulate to subentire, apex shortly acuminate. Racemes simple or branched near base, 2-20 cm; flowering pedicels ± clustered and perpendicular to axis of raceme, pubescent, with a minute setaceous bracteole at base. Buds with few to many, long, straight or slightly curved, rarely hooked, hairs. Floral tube 0.6-1 mm. Sepals reflexed in flower, white or pale green, ovate to broadly so, 2-3.7 × 1.4-2 mm, apex broadly to narrowly rounded to obtuse. Petals reflexed, white, ovate to broadly so, or depressed-obovate to broadly obovate, 1-2.4 × 1.2-3.1 mm, apex obcordate, apical notch 1/2-2/3 length of petal, petal lobes broadly rounded. Stamens spreading, shorter than to ca. as long as style; nectary wholly within floral tube and inconspicuous. Fruiting pedicel and mature fruit 4.4-7 mm. Fruit 3-3.9 × 1.8-3.3 mm, locules 2, obliquely obovoid to lenticular, abaxially flattened, base obliquely rounded or truncate to pedicel, with low, corky thickenings along margins and between locules, without prominent sulci.
