petiole (1.5–)2–5.2(–9) cm, glabrous or pubescent;

blade usually oblanceolate to spatulate, rarely obovate or lanceolate, 3.3–14(–20) cm × (05–)10–32(–47) mm, margins often pinnately lobed to lyrate, sometimes dentate or entire.

petiolate;

blade often pectinate (lobes linear), similar to basal, much smaller, margins pinnately lobed.

sessile;

blade linear to lanceolate, smaller distally, (base sagittate, appressed to stem), margins usually entire, rarely dentate.

somewhat lax, considerably elongated in fruit.

dense, slightly elongated in fruit, (flower buds oblong).

sepals spreading or ascending, oblong to linear-oblong, (2.5–)3.5–5 × 1–1.5 mm;

petals white, spatulate to oblanceolate, (3.5–)4–6.5(–7) × (0.5–)1–2 mm, margins not crisped, claw differentiated from blade (widest at base);

nectar glands confluent;

anthers oblong, (1–)1.5–2 mm, circinately coiled;

gynophore 0.5–1(–2) mm.

sepals erect, lanceolate to linear-lanceolate or ovate, (3–)3.5–5(–5.5) × 1–1.5(–2) mm;

petals white, linear to narrowly oblanceolate, 8–12.5(–16) × 0.3–0.5(–1) mm, margins strongly crisped, claw differentiated from blade, (slender, 2.5–4 mm, narrowest at base);

nectar glands surrounding bases of lateral stamens, median glands absent;

filaments subequal or slightly tetradynamous, 2.5–6.5(–10) mm;

anthers exserted, linear, 1.5.–2(–2.5) mm, slightly circinately coiled, (apiculate);
