Subshrub (softly woody), 2–7(–15) cm tall. Old stems dark brown or grey. Branches decumbent to ascending. Branchlets brown to redbrown. Vegetative internodes (1–)2–10(–20) mm long. Stem pubescence uniform, mostly eglandular pubescent and glandular puberulent (rare and sparse and/or hard to discern). Leaves decussate, erectopatent to spreading. Lamina elliptic or orbicular or spathulate, (3–)5–7(–10) × (2–)4–6(–9) mm. Adaxial surface of leaves bright green, glossy. Abaxial surface of leaves pale green, dull. Leaf hairs absent. Apex rounded or truncate. Base cuneate. Margin glabrous, crenate or serrate (bluntly). Marginal teeth or lobes in (0–)2–5 pairs. Petiole 3–4(–5) mm long. Inflorescence a solitary bibracteolate flower or a pair of flowers (rarely 3), 0.8–1.5 cm long at fruiting. Indumentum of peduncle, rachis, and pedicels moderately dense. Eglandular hairs of inflorescence antrorse (curved), white. Peduncle 0.1–0.5(–1.2) cm long, eglandular-pubescent; hairs all around peduncle. Rachis 0(–2) cm long, eglandular-pubescent, hairs all around rachis. Bracts alternate (spiralled), obtuse, glabrous, spathulate. Bract margins entire. Pedicels erecto-patent at anthesis, straight at fruiting, 1–3 mm long, eglandular-pubescent; hairs all around pedicel. Flowers: Calyx 4-lobed, (4–)6–7 (–8) mm long. Calyx lobes oblanceolate to obovate, subacute to obtuse. Calyx hairs absent (calyx glabrous). Calyx lobe margins entire. Corolla white at anthesis. Nectar guides absent. Corolla throat same colour as lobes or yellow. Corolla 5–6 mm diam. Corolla tube 1.5–3 mm long, 1.5–2 mm wide, glabrous. Corolla lobes glabrous. Posterior corolla lobe oblong, obtuse or emarginate or divided in two, 3– 4 × 1–2 mm. Lateral corolla lobes oblong, obtuse, flat, not enfolding stamens, 3–6 × 2–3 mm. Anterior corolla lobe oblong, obtuse, 3–5 × 2–3 mm. Stamen filaments white, (0.5–)1–2 mm long, not narrowed at base. Anthers purple, (1–)1.5 mm long. Nectarial disc glabrous. Ovary globose, obtuse, glabrous, 1–2 mm long. Style 0.5–3 mm long. Stigma 0.3– 0.5 mm wide. Capsules hygrochastic, narrowly angustiseptate (i.e., strongly flattened), didymous, 4– 5 × 3.5–5 mm, 1.5–2 mm thick, glabrous. Septicidal split of capsule extending to base. Loculicidal split of capsule extending 1⁄2 way to base. Seeds 10–55 per locule, strongly flattened, smooth-surfaced, ellipsoid, pale brown, 1–1.3 × 0.6–0.7 mm.
