Taproots gradually ramified distally. Stems ascending to suberect, 10–12(–30) cm. Leaves: basal leaves evergreen, sessile or abruptly or gradually narrowed to broad petiole, blade oblanceolate, obovate, spatulate, or rarely ± linear or ± orbiculate, ± flattened, 3–14 cm, margins entire, crisped, or toothed, apex truncate, emarginate, retuse, or rounded; cauline leaves alternate, intergrading with bracts, blade oblong to ovate, 5–10 mm, margins glandular-toothed, apex acute to occasionally obtuse. Inflorescences dense, paniculate to subumbellate cymes, 10–50-flowered; bracts alternate or opposite proximally, 2 at each flowering node distally, obovate to lanceolate, 2–4 mm, margins glandular-toothed, apex acute. Flowers pedicellate, not disarticulate in fruit; sepals 2, suborbiculate to broadly ovate, 4–6 mm, herbaceous at anthesis, margins glandular-toothed, apex obtuse to truncate; petals 7–10, usually pink-purple with pale and darker stripes, less often white, cream with pink-orange stripes, ± orange, or yellow, oblanceolate, obovate, or spatulate, (8–)12–20 mm; stamens 5–12; stigmas 2–4; pedicel 2–5 mm.
