simple, 5–15 cm, pubescent and viscid, with stipitate glands.

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

basal with blade 1-veined, oblanceolate, broadly spatulate, 1–4 cm × 2–8 mm, apex obtuse to acute, glandular-puberulent throughout, rarely subglabrous adaxially;

cauline in 3–6 pairs, sessile, reduced distally, blade lanceolate, narrowly elliptic, or oblanceolate, 2–4 cm × 2–8 mm, apex ± acute, glandular-puberulent throughout.

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.

usually with solitary terminal flower, sometimes cymose, to 8-flowered, open.

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 or angled near tip with flowers slightly nodding, 1–3 times longer than calyx, glandular-puberulent, often densely so.

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

calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 15–20 × 4–8 mm, papery, margins dentate, veins parallel, usually purple tinged, with pale commissures;

lobes ovate, 3–5 mm, glandular-puberulent, midrib triangular, margins purple tinged, broad, membranous, apex obtuse;

corolla bright pink, clawed, claw equaling calyx, broad and ligulate but abruptly contracted into limb, limb broadly cuneate, shallowly to deeply 2–4-lobed, 5–15 mm, lobes broad or narrow, appendages absent or to 2 mm, margins erose;

stamens slightly longer than corolla claw;

stigmas 3(–5), slightly longer than corolla claw.

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 by 6 (or 8 or 10) lanceolate teeth;

carpophore 1–2.5 mm.

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

carpophore 2–3 mm.

brown, broadly reniform, flattened, 2–2.5 mm, rugose, more coarsely so on margins.

rusty brown, often with gray bloom, broadly reniform, 1–1.8 mm, coarsely papillate.
