Descriptions
Cushion-forming subshrub, 1–4 cm tall. Old stems brown. Branches prostrate to ascending. Branchlets brown. Vegetative internodes 1–4 (–12) mm long. Stem pubescence uniform, eglandular pubescent. Leaves decussate, erect to erectopatent or recurved (in distal half of lamina). Lamina ovate or elliptic or orbicular or deltoid or spathulate or rhomboid, 2–3(–5) × 2–3 mm. Adaxial surface of leaves bronze green or dark green, dull. Abaxial surface of leaves bronze green or dark green, dull. Leaf hairs sparse to numerous or absent (rarely), on all parts of leaf, uniseriate eglandular or unicellular eglandular (rarely). Apex subacute to obtuse. Base cuneate. Margin minutely papillate or denticulate, lobed or pinnatifid, to bipinnatifid on basal lobes. Marginal teeth or lobes in 2–5 pairs. Petiole 3–6 mm long. Inflorescence a solitary bibracteolate flower or a pair of flowers (rarely 3), 0.2–1 cm long at fruiting. Indumentum of peduncle, rachis, and pedicels moderately dense to very dense. Eglandular hairs of inflorescence antrorse (curved), white. Peduncle 0– 2 cm long, eglandular-pubescent; hairs all around peduncle. Rachis 0–2 cm long, eglandular-pubescent, hairs all around rachis. Bracts paired and opposite, obtuse or subacute, eglandular-hairy adaxially and eglandular-hairy abaxially, spathulate. Bract margins shallowly to deeply lobed. Pedicels patent at anthesis, straight at fruiting, 0–2 mm long, eglandular-pubescent; hairs all around pedicel. Flowers: Calyx 4(–5)-lobed (5th lobe rarely present, shorter, entire, narrow), 4–7 mm long. Calyx lobes oblanceolate or oblong or spathulate, subacute to obtuse. Calyx hairs on both abaxial and adaxial surfaces, eglandular. Calyx lobe margins pinnatifid or shallowly lobed. Corolla white at anthesis. Nectar guides absent. Corolla throat same colour as lobes. Corolla (4–)5–7 mm diam. Corolla tube (3.5–)4– 7 mm long, 1.5–2 mm wide, glabrous or hairy outside, hairs short. Corolla lobes glabrous or pubescent abaxially. Posterior corolla lobe circular or elliptic or deltoid, obtuse or emarginate or divided in two, 2–3 × 2–4 mm. Lateral corolla lobes circular or elliptic, obtuse, flat, not enfolding stamens, 2–3(–4) × 2–4 mm. Anterior corolla lobe elliptic, obtuse, 2–3 × 1.5–2.5 mm. Stamen filaments white, 1.5(–2) mm long, not narrowed at base. Anthers pink to magenta, 1–1.5 mm long. Nectarial disc glabrous. Ovary ovoid or globose, obtuse, eglandular hairy, 1–1.5 mm long. Style 1.5–2.5 mm long. Stigma 0.4–0.5 mm wide. Capsules hygrochastic, narrowly angustiseptate (i.e., strongly flattened), emarginate to didymous, 3–4 × 3–4 mm, 2(–3) mm thick, hairy. Hairs eglandular. Septicidal split of capsule extending 1⁄3 way to base (split to base in old capsules). Loculicidal split of capsule extending 3⁄4 way to base or to base. Seeds 10–20 per locule, strongly flattened, smooth-surfaced (weakly flattened and minutely papillate), ellipsoid to obovoid, pale brown to dark brown, (0.6–)0.8–1.1 × (0.5–)0.6–0.7 mm.
