Taproots gradually ramified distally. Stems procumbent to suberect, 10–12 (–30) cm. Leaves: basal leaves evergreen, sessile, blade narrowly linear to linear-oblanceolate, flattened or slightly grooved on adaxial surface, 2–10 cm, margins entire, apex obtuse to acute; cauline leaves absent, or alternate and intergrading with bracts, blade linear, 5–18 mm, margins entire or eglandular-toothed, apex acute. Inflorescences paniculate cymes, 20–100-flowered; bracts alternate proximally, 2 at each flowering node distally, ovate, 2–5 mm, margins toothed to glandular-toothed, apex obtuse. Flowers pedicellate, not disarticulate in fruit; sepals 2, suborbiculate, 1.5–3 mm, herbaceous at anthesis, margins glandular-toothed, apex rounded to truncate; petals 4–9 (–11), white with pink veins to pink to magenta, oblong or obovate, 5–13 mm; stamens 5–6; stigmas 2 or 3; pedicel 5–13 mm.
