several, simple proximal to inflorescence, 30–80 cm, puberulent, becoming subglabrous near base.

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

withering proximally, in whorls of 4, ± sessile to short-petiolate, largest in mid-stem region;

blade lanceolate to ovate-lanceolate, 3–10 cm × 4–40 mm, apex acuminate, puberulent on both surfaces, sparsely so adaxially.

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.

paniculate, open, bracteate, bracteolate, branches elongate, puberulent;

bracts and bracteoles linear-lanceolate, 2–15 mm.

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

straight, often with 1 or 2 pairs of bracteoles, slender, 1/2–3 times calyx, glabrous or scabrous-puberulous.

calyx obscurely 10-veined, broadly campanulate, becoming obtriangular in fruit, 7–11 × 6–10 mm, herbaceous, margins dentate, very narrow, membranous, sparsely puberulent, lobes broadly triangular, 2–3 mm;

corolla white, ca. 2 times longer than calyx, limb obtriangular, narrowed into claw, divided ca. 1/2 its length into 4–12 lobes, appendages absent;

stamens equaling petals;

styles 3, longer than petals.

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;
