mostly basal;

basal marcescent, long-petiolate, densely tufted, blade 1-veined, narrowly oblanceolate, 2–10(–20) cm × 2–12(–20) mm, not fleshy, base tapering to petiole, apex acute to obtuse, finely puberulent on both surfaces;

cauline in 1–3 pairs, sessile, much reduced, blade linear-lanceolate, not fleshy.

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.

1–5(–7)-flowered, with terminal flower and lateral, open, pedunculate cymes often reduced to single flowers, bracteate;

bracts narrowly lanceolate, 3–10(–20) mm.

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

erect, elongate, 0.5–4.5 cm, glandular-puberulent.

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.

calyx prominently 10-veined, those to lobes lance-shaped broadened and thickened distally, commissural veins slender, not forked distally, campanulate, 10–12 × 3.5–5 mm in flower, enlarging to 15 × 10 mm in fruit, not contracted around carpophore, papery, margins dentate, glandular-pubescent, viscid, veins parallel, with pale commissures, lobes patent, ovate, 1.5–4 mm, rigid, margins broad, membranous;

corolla off-white to dingy purple-red, clawed, claw exceeding calyx, ciliate proximally, broadened distally, limbs erect, 2–4-lobed, less than 1/2 length of calyx, lobes 2–5 mm, appendages 2–4, 0.5–1 mm;

stamens slightly exserted;

filaments lanate, expanded at base;

styles 3–5, ± equaling calyx.

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

carpophore ca. 1 mm.

slightly longer than calyx, opening by 3–5 teeth;

carpophore 1.5–2.5 mm.

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

papillae slightly longer than broad.

brown, reniform, 1.2–2 mm, margins with large, inflated papillae, rugose on sides.
