Low subshrub, 5–15 cm tall. Old stems brown. Branches decumbent to ascending. Branchlets brown or red-brown or purplish. Vegetative internodes (1–)2–5(–8) mm long. Stem pubescence absent or bifarious (at distal end of internode), eglandular pubescent. Leaves decussate, erecto-patent to recurved. Lamina linear to oblong (narrowly), (4–)8–12(–15) × (1–)1.5–3 mm. Adaxial surface of leaves green, glossy. Abaxial surface of leaves pale green, dull. Leaf hairs sparse to scattered, along margins (especially at base), uniseriate eglandular. Apex rounded or truncate (with swollen hydathode beneath). Base cuneate. Margin ciliate (especially at base), entire. Petiole 1–3 mm long. Inflorescence racemose, unbranched, 1–2.5(–4) cm long at fruiting, with (2–)3–5(–6) flowers. Indumentum of peduncle, rachis, and pedicels absent. Peduncle (0.3–)0.8–1.5(–2) cm long, glabrous. Rachis (0–) 0.2–1.2(–1.5) cm long, glabrous. Bracts alternate (spiralled) (basal pair sometimes subopposite), obtuse, glabrous (rarely a few hairs on margin at base), linear to elliptic (narrowly). Bract margins entire. Pedicels erecto-patent at anthesis to suberect at anthesis, incurved at fruiting, (4–)6–12(–15) mm long, glabrous. Flowers: Calyx 4-lobed, (3–)4–7(–9) mm long. Calyx lobes lanceolate to deltoid or elliptic or obovate, subacute to obtuse. Calyx hairs absent (calyx glabrous). Calyx lobe margins entire. Corolla white at anthesis. Nectar guides obscure (usually 0–2(–4)) or absent, confined to posterior corolla lobe if present. Colour ring and nectar guides pink or absent. Corolla throat same colour as lobes. Corolla 5–8(–10) mm diam. Corolla tube (1.2–)1.5– 2.5(–3.5) mm long, (1–)1.5–2 mm wide, glabrous. Corolla lobes glabrous. Posterior corolla lobe elliptic to ovate, obtuse, 5–6(–7) × 3–4(–5) mm.

Style (2–)3(–4) mm long. Stigma 0.4–0.7 mm wide. Capsules xerochastic, broadly angustiseptate (i.e., weakly flattened), truncate to emarginate, 3.5–4 × 3.5–4 mm, 1.5 mm thick, glabrous. Septicidal split of capsule extending to base. Loculicidal split of capsule extending 1⁄4–1⁄2 way to base.
