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

mostly in dense basal tufts;

basal blades oblanceolate to elliptic, 1–3.5 cm × 3–10 mm, narrowed to base, apex acute, scabrous-puberulent to subglabrous;

cauline in 2–3 pairs, distal sessile, reduced, blade linear-lanceolate to lanceolate, 1.5–4 cm × 2–6 mm.

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, (1–)3–5(–7)-flowered, open, bracteate, bracteolate, pubescent and viscid with stipitate glands;

cyme open, slender-branched;

bracts and bracteoles narrowly lanceolate, 2–15 mm, herbaceous.

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

divaricate, often curved near apex and/or at base, slender, 1/2–2 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.

calyx prominently 10-veined, campanulate, 6–10 × 2–4 mm in flower, broadening in fruit and becoming obconic with ± constricted base, ± as broad as long, pubescent and glandular, veins parallel, with pale commissures, lobes triangular, 1–2 mm, margins broad, membranous, apex acute;

corolla yellowish white, sometimes tinged with pink, clawed, claw equaling or longer than calyx, limb deeply lobed, lobes 4, linear, 4–8 mm, appendages 2, narrow, ca. 1 mm;

stamens exserted, equaling petals;

styles 3, filamentous, much longer than petals and stamens, exceeding 2 times calyx.

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

carpophore 1.5–2.5 mm.

obovoid, equaling calyx and often splitting it, opening by 6 recurved teeth;

carpophore 2–3 mm.

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