erect, simple proximal to inflorescence, 7–20 cm, with 2–4 pairs of leaves, short retrorse-pubescent proximally, stipitate-glandular and viscid distally, with purple-septate hairs.

basal few, usually withering by time of anthesis, blade spatulate;

cauline numerous, 2 per node, blade 1-veined, ovate-lanceolate to oblanceolate, 3–7 cm × 7–30 mm, margins entire, apex acute.

basal pseudopetiolate, tufted, blade narrowly oblanceolate, 1.5–5 cm × 1.5–5 mm, base narrowed into long pseudopetiole, retrorse-puberulent on both surfaces;

cauline sessile, connate at base, blade linear to linear-lanceolate or linear-oblanceolate, 1–4 cm × 1.5–4 mm, apex acute.

many-flowered, open, bracteate;

primary branches racemose, elongate, with sessile or shortly pedunculate cymes of 1–6 flowers per node;

bracts narrowly lanceolate, 3–12 mm, hyaline-margined, apex acute.

1(–3)-flowered.

ascending, ± straight, 1–2 times calyx, broadening at calyx base.

erect, rarely somewhat curved or reflexed near tip, 0.5–2 cm, 1/2–3 times calyx, viscid with stipitate-glandular and purple-septate hairs, hairs less than 1/2 pedicel diam.

calyx often obscurely ca. 20-veined, elliptic, abruptly contracted at base, opening constricted to 1/2 its diam., slightly inflated in flower, 7–10 × 3–4 mm, in fruit tightly enveloping capsule, ovoid, thin, enlarging to 9–13 × 5–7 mm, herbaceous, margins narrow, membranous, dentate with broadly triangular lobes to 1 mm, glabrous, veins obscure, usually purple tinged, without conspicuous, pale commissures, longitudinal, parallel, not obviously reticulate;

petals white, clawed, claw equaling calyx, limb deeply 2-fid into 2 spatulate lobes, to 5 mm, appendages ca. 0.5 mm;

stamens exserted, to 2 times length of calyx;

filaments usually dark purple;

stigmas 3, exserted, to 2 times length of calyx.

10–12 mm diam.;

calyx prominently 10-veined, ellipsoid, somewhat inflated and contracted at mouth to 1/2–2/3 diam., 12–14 × 6–7 mm in flower, 14–17 × 7–8 mm in fruit, to 2 times as long as broad, papery, margins dentate, lobes 5, patent, ca. 2 mm, with broad, membranous margins, apex obtuse, pubescent, hairs short and stipitate-glandular and long purple-septate;

corolla pink to purple, slightly longer than calyx, limb 2-lobed, 4–5 mm, with 2 short (ca. 0.5 mm) appendages;

stamens equaling corolla;

stigmas (4–)5, equaling corolla.

ovoid, equaling calyx and sometimes splitting it, opening by 6 recurved, narrowly lanceolate teeth;

carpophore ca. 1 mm.

equaling calyx, opening by 5 recurved teeth, which later split into 10;

carpophore very short or absent.

grayish brown, plump, broadly reniform, 0.6–1 mm, with concentric rings of papillae;

papillae slightly longer than broad.

dark brown, reniform, not winged, 0.7–1 mm, papillate-tuberculate.
