Shrubs, decumbent, straggling and rooting, forming low, rounded clumps or mats, 1–5 dm. Stems: internodes (4-) or 6-lined at first, then terete. Leaf-blades linear-subulate, 13–25 × 0.5–0.8 mm, base articulated, parallel, margins revolute, apex rounded to retuse, midrib unbranched. Inflorescences narrowly pyramidal, 1–3-flowered, with 1–3 (–5) -flowered dichasia from to 5 proximal nodes, without additional flowering branches; pedicels 0.5 mm. Flowers 12–14 mm diam.; sepals deciduous, not enclosing capsule, 5, linear-subulate, unequal, (3–) 4.5–7 × 0.5–0.8 mm; petals 5, golden yellow, oblanceolate-oblong, 5–7.5 mm; stamens deciduous, 100; ovary 3-merous. Capsules ovoid, 3–4 × 2–2.5 mm. Seeds carinate, 0.7 mm; testa not seen.


Phenology: Flowering summer (Aug).
Habitat: Dry habitats (pine woods, granite outcrops, roadside embankments), inner coastal plain and foothills
Elevation: 100–300 m
