erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally.

15–45 cm, pubescent and glandular-viscid distally, sparsely pubescent to ± glabrous proximally.

2 per node, blade with coarse, ascending, scabrous pubescence on both surfaces;

basal few, withering, blade oblanceolate to spatulate-petiolate, 0.5–5 cm × 3–15 mm;

cauline blades oblanceolate to lanceolate, 1–7 cm × 1–15 mm, apex obtuse or shortly acuminate to acute.

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.

open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally.

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.

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

5–8 mm diam.;

calyx prominently 10-veined, narrowly tubular-ovoid in flower, ovoid in fruit, constricted at mouth, 7–10 × 3–5 mm, membranous between veins, margins dentate, hispid, hairs ca. 2 mm, veins parallel, lobes lanceolate, 2–2.5 mm, apex greenish purple, acute;

petals white or pink, often with dark spot or dark pink throughout, clawed, claw equaling calyx, limb elliptic to obovate, lobed or unlobed, to 6 mm, appendages 2, oblong to narrowly lanceolate, 1–1.5 mm;

stamens equaling or shorter than calyx;

stigmas 3, included in 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.

equaling calyx, opening with 6 recurved, narrowly triangular teeth;

carpophore shorter than 1 mm, pubescent.

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

carpophore 2–3 mm.

dark reddish brown, reniform, angular with concave, radially ridged faces, broad outer edge transversely ridged and verrucose, ca. 0.5 mm broad.
