erect, simple or with ascending branches, (20–)40–100 cm, coarsely puberulent, stipitate-glandular, viscid distally.

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.

mid and proximal stem pairs connate, blade 1–several-veined, oblanceolate to narrowly lanceolate, (3–)5–12 cm × (3–)8–15 mm, apex acute, veins parallel;

basal leaf blades oblanceolate and ± obtuse, sparsely to moderately puberulent on both surfaces, rarely subglabrous.

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

several–many-flowered, open, bracteate;

bracts resembling leaves but smaller.

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

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.
