blade prominently 3–5-veined, ovate-acuminate, round at base, (4–)6–10(–13) cm × (20–)30–50(–90) mm, appressed-pubescent on both surfaces.

basal numerous, tufted, petiolate, petiole ciliate, blade oblanceolate, 3–10 cm × 8–18 mm, base spatulate, apex acute to obtuse, glabrous on both surfaces, rarely puberulent;

cauline in 2–4 pairs, broadly petiolate to sessile, reduced distally, blade oblanceolate to narrowly elliptic or lanceolate, 1–10(–30) cm × 4–16(–30) mm, margins ciliate, apex acute, shortly acuminate, glabrous.

bracts leaflike, lanceolate, 4–40 mm.

ascending, recurved near apex, ca. equaling calyx.

erect in flower, sharply deflexed at base in fruit, 1/2–1 times length of calyx.

nocturnal;

calyx prominently 10-veined, tubular to narrowly campanulate and 6–9 × 3–4 mm in flower, turbinate and 10–12 × 4–5 mm in fruit, narrowed proximally around carpophore, veins parallel, green, broad, with pale commissures, puberulent, sometimes with few glands, lobes triangular-acute, 2–3 mm;

corolla white, clawed, claw equaling calyx, broadened into limb, limb obtriangular, deeply lobed, 7–9 mm, lobes ca. 8, linear, appendages minute;
