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

several, erect, freely branched, leafy, elongate, 30–80 cm, scabrid-puberulent and glandular-viscid.

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;

basal long-petiolate, blade oblanceolate, (2–)5–18 cm × 5–30 mm, base narrowed into petiole, apex ± acute, glandular-puberulent on both surfaces;

cauline not greatly reduced in distal stem, blade 5–15 cm × 10–20 mm, viscid glandular-pubescent, sparsely so in shade forms, proximal petiolate and blade oblanceolate, distal sessile and blade lanceolate, apex acute.

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.

open, elongate, dichotomously branched, branches ascending, bracteate;

bracts leaflike, reduced distally.

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

ascending, may be partially deflexed, rather slender, longer than calyx, viscid glandular-pubescent with septate hairs, septa colorless.

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.

calyx prominently 10-veined, tubular in flower, 8–12 × 2–4 mm, swelling to campanulate and 5–7 mm broad in fruit, not contracted proximally around carpophore, viscid glandular-pubescent, especially on veins, veins parallel, green, with pale commissures, those to lobes broadened distally, lobes erect, narrowly lanceolate, 3–4 mm, rigid, setose-scabrous, glandular-viscid, apex recurved;

corolla greenish white, claw equaling calyx, limb 2-lobed, ca. 3 mm, appendages ca. 0.5 mm, margins erose;

stamens equaling petals;

styles 3, equaling petals.
