Inflorescences: flowers borne singly on peduncles; bracts 2, ovate to broadly lanceolate, 5–7 mm, margins entire, apex acute to acuminate. Flowers sessile, not disarticulate in fruit; sepals 2, decussate with bracts, ovate, 4–9 mm, herbaceous, margins entire, not glandular, apex acute; petals 5–9, white, sometimes with pink veins, or pinkish, obovate, 12–26 mm; stamens 9–15; stigmas 5–8. Capsules 6–9 mm. Seeds 40–50, 1.5 mm, shiny. 2n = 20.
