Subshrub, (2–)5–10(–20) cm tall. Old stems brown to grey. Branches decumbent. Branchlets brown or purplish. Vegetative internodes 2–5(–8) mm long. Stem pubescence uniform, eglandular pubescent (rarely a few glandular hairs also present). Leaves decussate, erecto-patent to spreading. Lamina obovate, (4–)5–7(–12) × (2.5–)4– 6(–11) mm. Adaxial surface of leaves dark green or purple (often greyish), dull. Abaxial surface of leaves dark green or purple, dull. Leaf hairs dense, on all parts of leaf, uniseriate eglandular and uniseriate glandular with globular head (occasionally). Apex obtuse or rounded or retuse or truncate. Base cuneate. Margin ciliate and glandular-ciliate (very few glandular hairs), crenate (deeply). Marginal teeth or lobes in (1–)2–3 pairs. Petiole 0–1 mm long. Inflorescence a solitary bibracteolate flower or a pair of flowers (rarely 3), 0.2–0.6 cm long at fruiting. Indumentum of peduncle, rachis, and pedicels sparse to moderately dense. Eglandular hairs of inflorescence patent, white. Peduncle 0.2–0.5(–4) cm long, eglandular-pubescent; hairs all around peduncle. Bracts paired and opposite, obtuse, eglandular-hairy adaxially and eglandular-hairy abaxially (usually with some glandular hairs), spathulate (narrowly). Bract margins entire. Pedicels erecto-patent at anthesis, straight at fruiting, 0.3–1 mm long, glabrous or eglandular-pubescent; hairs all around pedicel. Flowers: Calyx 4-lobed, 4–5(–6) mm long. Calyx lobes oblong or elliptic, subacute or obtuse. Calyx hairs on both abaxial and adaxial surfaces, mixed eglandular and glandular. Calyx lobe margins entire. Corolla white at anthesis. Nectar guides absent. Corolla 7–10 mm diam. Corolla tube 2–3 mm long, 1 mm wide, glabrous. Corolla lobes glabrous. Posterior corolla lobe circular to elliptic, emarginate or divided in two, 3–4 × (1.8–)2.5–3 mm. Lateral corolla lobes elliptic, obtuse, flat, not enfolding stamens, 4–5 × 4–4.5 mm. Anterior corolla lobe elliptic, obtuse, 4–4.5 × 2.5–3 mm. Stamen filaments white, 2(–3) mm long, not narrowed at base. Anthers pink or magenta or mauve, 1–1.5 mm long. Nectarial disc glabrous. Ovary ovoid, acute, glabrous, 1– 1.5 mm long. Style 1–1.5 mm long. Stigma 0.3– 0.4 mm wide. Capsules hygrochastic, narrowly angustiseptate (i.e., strongly flattened), emarginate, 3–4 × 3–4 mm, 0.8–1 mm thick, glabrous. Septicidal split of capsule extending 1⁄4 way to base. Loculicidal split of capsule extending 1⁄2 way to base. Seeds approx. 10–15 per locule, strongly flattened, smoothsurfaced, ellipsoid, straw yellow to pale brown, 0.8– 1 × 0.6–0.7 mm.
