Plants perennial. Stems prostrate, often buried in sand, usually much branched, forming large mats, succulent, densely glandular-pubescent to glabrous. Leaves: 1–6 cm; blade deltate-ovate to reniform, 2.2–4.8 × 2.7–5.2 cm, margins usually entire, sometimes slightly repand and undulate, surfaces glabrous or viscid-puberulent. Inflorescences: peduncle longer than subtending petiole; bracts ovate, 5–9 × 3–5 mm, thin, yellowish green, glandular-pubescent; flowers 17–35. Perianth: tube yellowish green, 6.5–18 mm, limb yellow, 8–13 mm diam., lobes slightly to moderately reflexed. Fruits winged, ± rhombic in profile, attenuate at both ends, 8–15 × 6–14 mm, scarious; wings 4–5, thin walled, small, cavities extending into wing.
