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.

2 per node, sessile or short-petiolate, largest near mid-stem region, reduced and withering proximally, blade elliptic-lanceolate, base cuneate or rounded, apex gradually acuminate and acute, glabrous to puberulent.

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

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

1/2–21/2 times calyx, apex often becoming deflexed, glabrous to hirsute.

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.

carpophore 1.5–2.5 mm.

globose, equaling calyx, opening by 3 broad teeth that sometimes split to form 6;
