Subshrub or loose cushion or matforming subshrub, 2–5 cm tall. Old stems brown. Branches prostrate. Branchlets red-brown. Vegetative internodes (1–)2–5(–7) mm long. Stem pubescence sparsely bifarious or absent, eglandular pubescent. Leaves decussate, erecto-patent to spreading. Lamina oblanceolate or oblong or elliptic or rhomboid, (2–)4–7(–10) × (1–)2–4(–6) mm. Adaxial surface of leaves green or dark green, glossy. Abaxial surface of leaves green or pale green or purple, dull. Leaf hairs absent. Apex obtuse to rounded. Base cuneate. Margin glabrous or ciliate (on petiole only), entire or crenate (shallowly). Marginal teeth or lobes in 0–3 pairs. Petiole (1–)2– 3(–5) mm long. Inflorescence a solitary bibracteolate flower or a pair of flowers (rarely), 0.5–0.8 cm long at fruiting. Indumentum of peduncle, rachis, and pedicels absent. Peduncle 0.1–0.2 cm long, glabrous. Bracts paired and opposite, obtuse or subacute, glabrous or eglandular ciliate (at base), spathulate to obovate. Bract margins entire. Pedicels erecto-patent at anthesis, straight at fruiting or incurved at fruiting, 1–5(–7) mm long, glabrous. Flowers: Calyx 4(–5)-lobed (small 5th lobe rarely present), (3.5–)4– 5(–7) mm long. Calyx lobes oblanceolate or obovate or spathulate, obtuse. Calyx hairs absent (calyx glabrous). Calyx lobe margins usually entire or toothed (rarely). Corolla white at anthesis or pink at anthesis or violet at anthesis. Nectar guides absent. Corolla throat same colour as lobes. Corolla 7–9 mm diam. Corolla tube 2–4 mm long, 1–1.5 mm wide, glabrous. Corolla lobes glabrous. Posterior corolla lobe circular or elliptic or rhomboid, obtuse, 3.5–4.5 × 2– 4 mm. Lateral corolla lobes asymmetrically elliptic or oblong or ovate or deltoid, obtuse, flat, not enfolding stamens, 2.5–5.5 × 2–4 mm. Anterior corolla lobe elliptic or oblong or rhomboid, subacute or obtuse, 2.5–4.5 × 1.5–2.5 mm. Stamen filaments white, 1.5–2.5 mm long, not narrowed at base. Anthers magenta, 1 mm long. Nectarial disc minutely ciliolate. Ovary ovoid or fusiform, acute or subacute, glabrous, 1 mm long. Style 2.5–3.5 mm long. Stigma 0.5 mm wide. Capsules hygrochastic, narrowly angustiseptate (i.e., strongly flattened), emarginate or didymous, (3–)3.5–4 × 4–4.5 mm, 2 mm thick, glabrous. Septicidal split of capsule extending to base. Loculicidal split of capsule extending 1⁄4–1⁄2 way to base. Seeds 25–35 per locule, strongly flattened, smooth-surfaced, ellipsoid or obovoid, pale brown, 0.8–1 × 0.5–0.6 mm.
