Herbs glabrous, villous, strig­illose, or glandular puberulent, especially distally, sometimes glabrous distally. Stems erect or decumbent, slender, wiry, usually well-branched, 5–25 (–50) cm. Leaves: proximalmost not clustered near base; blade linear to narrowly elliptic or narrowly oblanceolate, 0.5–2.5 (–3) × 0.1–0.15 (–0.5) cm, base attenuate, margins sparsely serrulate to coarsely serrate, apex acuminate. Flowers opening near sunrise; floral-tube 1.5–5.5 mm, ± densely villous on proximal 1/2 inside; sepals 3.5–8 (–12) mm, re­flexed in pairs; petals (3.5–) 5–15.5 mm, each usually with 1 or 2 red dots basally; episepalous filaments (1.4–) 2.1–5.5 mm, epipetalous filaments (0.7–) 1.2–3.2 mm, anthers 1–2.4 mm, pollen with less than 5% of grains 4-pored or 5-pored; style (3.2–) 4–12 (–15) mm, stigma well exserted beyond anthers at anthesis. Capsules 20–43 × 0.7–1.5 (–2) mm; subsessile. Seeds 0.8–1.6 × 0.4–0.6 mm.
