several, erect, simple, 15–50 cm, puberulent, viscid-glandular distally.

erect, simple proximal to inflorescence or with few basal branches, branched distally, to 75 cm.

mostly basal;

basal marcescent, long-petiolate, densely tufted, blade 1-veined, narrowly oblanceolate, 2–10(–20) cm × 2–12(–20) mm, not fleshy, base tapering to petiole, apex acute to obtuse, finely puberulent on both surfaces;

cauline in 1–3 pairs, sessile, much reduced, blade linear-lanceolate, not fleshy.

2 per node, gradually reduced distally;

basal blades oblanceolate, 6–12(–14) cm × 20–45 mm;

cauline blades ascending, conspicuously veined, broadly elliptic to lanceolate, 1–11 cm × 3–40 mm, apex acute, shortly acuminate, densely pubescent on both surfaces.

1–5(–7)-flowered, with terminal flower and lateral, open, pedunculate cymes often reduced to single flowers, bracteate;

bracts narrowly lanceolate, 3–10(–20) mm.

cymose, 3–15-flowered, bracteate;

cyme open, flowers held on ascending branches;

bracts leaflike, narrowly lanceolate, 1–5 cm, apex acuminate.

erect, elongate, 0.5–4.5 cm, glandular-puberulent.

ascending, straight, 1/3–3 times longer than calyx.

calyx prominently 10-veined, those to lobes lance-shaped broadened and thickened distally, commissural veins slender, not forked distally, campanulate, 10–12 × 3.5–5 mm in flower, enlarging to 15 × 10 mm in fruit, not contracted around carpophore, papery, margins dentate, glandular-pubescent, viscid, veins parallel, with pale commissures, lobes patent, ovate, 1.5–4 mm, rigid, margins broad, membranous;

corolla off-white to dingy purple-red, clawed, claw exceeding calyx, ciliate proximally, broadened distally, limbs erect, 2–4-lobed, less than 1/2 length of calyx, lobes 2–5 mm, appendages 2–4, 0.5–1 mm;

stamens slightly exserted;

filaments lanate, expanded at base;

styles 3–5, ± equaling calyx.

nocturnal, 20–25 mm diam.;

calyx prominently 10-veined, ovate-elliptic, fusiform, narrowed to both ends and constricted around carpophore, 15–24(–40) × ca. 3 mm in flower, swelling to 10 mm diam. in fruit, thin and papery, margins dentate, with pale commissures;

lobes erect, often recurved in fruit, linear-lanceolate, long, narrow, (3–)5–10(–15) mm, apex acuminate, short-pubescent, glandular, interspersed with long eglandular hairs, veins anastomosing;

corolla white, often pink tinged, clawed, claw equaling calyx lobes, limb deeply 2-lobed, lobes usually narrow, appendages 0.5–1.5 mm broad, margins entire or erose;

stamens shorter than petals;

styles 3, shorter than petals.

slightly longer than calyx, opening by 3–5 teeth;

carpophore 1.5–2.5 mm.

ovoid, constricted at mouth, equaling or slightly longer than calyx tube, opening by 6 recurved teeth;

carpophore 1–3 mm.

brown, reniform, 1.2–2 mm, margins with large, inflated papillae, rugose on sides.

dark brown to black, with gray bloom, broadly reniform, 0.8–1 mm, strongly tuberculate.
