Herbs glandular puberulent, sometimes also moderately or sparsely villous. Stems simple or loosely branched, 6–20 cm, usually flowering only distally. Leaves cauline, sometimes with lower ones clustered near base, 0.5–3.5 × 0.5–1 cm; petiole 0–0.6 cm; blade elliptic-lanceolate to elliptic, margins crenate-dentate or -serrulate. Inflorescences only at terminal nodes, nodding at anthesis. Flowers opening at sunset; floral tube 1.5–3 mm, villous in proximal 1/2 inside; sepals 1–1.5 mm; petals white, fading pinkish, 1.5–2.5 mm; episepalous filaments 1–2 mm, epipetalous filaments slightly shorter, anthers 0.4–0.9 mm; style 3–4.5 mm, villous near base, stigma 0.5–0.8 mm diam., surrounded by anthers at anthesis. Capsules cylindrical and thickened proximally, spreading, straight to arcuate or weakly sigmoid, terete, thickened near base, tapering distally, 8–12 × 2–3 mm, regularly but tardily dehiscent. Seeds monomorphic, light brown, ca. 1 mm, finely reticulate.
