petiole (1–)2–8(–14) cm, ciliate;

blade usually oblanceolate to ovate, rarely oblong, (2–)6.5–20(–29) cm × 10–42(–50) mm, margins entire, (surfaces glabrous or pubescent).

sessile;

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

(ascending);

sessile;

blade lanceolate to oblong-lanceolate, (0.8–)1.6–8.5(–14) cm × 2–13(–28) mm, (base amplexicaul to sagittate), margins entire, (surfaces glabrous or pubescent).

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

sometimes corymbose, lax or dense, elongated or not in fruit, (flower buds ovate to lanceolate).

sepals erect to ascending, oblong to linear-oblong, (3–)3.5–6(–8) × (0.8–)1–1.8(–2) mm;

petals white to lavender, linear to narrowly oblanceolate, (6–)6.5–11(–14.5) × 0.5–0.7(–1) mm, margins strongly crisped, claw differentiated from blade, (slender, 2–4 mm, narrowest at base);

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

filaments subequal, (2.5–)4.5–8.5(–10.5) mm;

anthers exserted, linear to narrowly oblong, 2–3.5(–4.5) mm, circinately coiled, (apiculate);

sepals erect, ovate to oblong, (2.5–)3–6(–10) × (1–)1.5–2(–2.5) mm;

petals white or lavender to purple, oblanceolate to spatulate or linear, (5–)7–14(–19) × (0.5–)1–3(–4) mm, margins slightly crisped between blade and claw, claw differentiated from blade, [slender, (2–)3–6.5(–10) mm, narrowest at base];

nectar glands confluent and subtending bases of stamens, sometimes only lateral;

filaments tetradynamous, median pairs 3–5.5(–8) mm, lateral pair (2–)2.5–4.5(–7) mm;
