Herbs erect, 2–7 dm, sometimes with ascending branches distally. Stems: internodes 4-lined or 4-angled at first, then terete. Leaves sessile, sometimes amplexicaul; blade usually ovate or triangular-ovate to elliptic or oblong, rarely oblanceolate, 20–65 × 10–22(–30) mm, base shallowly cordate, apex usually rounded, rarely obtuse to retuse, gland dots laminar (relatively dense, large) and intramarginal (relatively small). Inflorescences laxly cylindric to pyramidal, 3–15-flowered from terminal node, sometimes with subsidiary inflorescences from to 4 proximal nodes and flowering branches from to 6 further nodes. Flowers 10–15 mm diam.; sepals oblong to elliptic-oblong or oblong-lanceolate, 4–7(–8) × 1–2 mm, apex acute to acuminate; petals oblong-elliptic to oblanceolate, 6–9(–10) mm; stamen fascicles 4–6.5 mm; filaments 1/5 connate; styles 2–3.5 mm. Capsules cylindric to ellipsoid or ovoid-ellipsoid, (8–)9–10(–12) × 4–5 mm, apex acute. Seeds 0.5–1.2 mm. 2n = 38.
