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

decumbent to ascending, scarcely branched, weak, leafy, with several basal, procumbent, nonflowering shoots, 10–40 cm, softly pilose.

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.

2 per node, blade 2–9 cm × 10–25 mm;

proximal petiolate, petiole ciliate, blade broadly oblanceolate;

distal sessile, blade obovate to elliptic or lanceolate, spatulate, margins ciliate, apex acute or obtuse, apiculate, glabrous to sparsely pilose.

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

terminal, cymose, usually 3-flowered, open, bracteate;

bracts foliaceous.

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

shorter than calyx, pilose, with colorless, large, stipitate glands.

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, funnelform, umbilicate in fruit, constricted around carpophore, 20–28 × 5–9 mm, broadening distally, papery, thinly pilose, veins parallel, green, with pale commissures, lobes lanceolate, 4–7 mm, apex acute;

corolla showy, pink or white, large, clawed, claw equaling calyx, limb fan-shaped, 15–25 mm, laciniate into many narrow segments, appendages absent;

stamens equaling calyx;

stigmas 3(–4), equaling calyx.

equaling calyx, opening by 6 (or 8 or 10) lanceolate teeth;

carpophore 1–2.5 mm.

ovoid, included in calyx, opening by 6 (or 8) teeth;

carpophore 7–10 mm.
