Shrub, 0.05-0.2 m tall. Branches ascending to erect; branchlets red-brown to grey with thick corky bark; vegetative internodes 1-4 mm long. Stem pubescence bifarious or uniform, eglandular; eglandular stem hairs patent or deflexed. Leaves erecto-patent; lamina lanceolate to oblanceolate, coriaceous and rigid, folded, 5-15 × 2-6 mm; apex acute; base cuneate; margin red, rounded, smooth, crenate to serrate, teeth in 3-8 pairs. Adaxial surface of leaves with minute twin, headed glandular hairs on midrib, green to bronze green, dull, with scattered stomata. Abaxial surface of leaves glabrous, pale green, dull, with numerous stomata. Midrib depressed to grooved above. Petiole not winged, 1-5 mm long. Inflorescence with (30)50-70 flowers, 1-2 cm long; peduncle 0.3- 0.6 cm long; rachis 0.5-1.5 cm long, pubescent; bracts opposite and decussate, acute, ciliate with both eglandular and rare glandular hairs, deltoid. Pedicels eglandular-pubescent, much shorter than bracts, 0- 0.2 mm long. Calyx divisions equally deep; calyx 2.8-3.3 mm long; calyx lobes 4, all similar, ovate to deltoid, subacute to obtuse, glandular- and eglandular-ciliate. Corolla 4-5 mm diam., bright pink at anthesis, mauve after pollination, throat pink; corolla tube 1.8-2.0 mm long, 1 mm wide, cylindric to funnelform, shorter than calyx, glabrous; corolla lobes glabrous; posterior corolla lobe longer than tube, elliptic to ovate, obtuse, spreading to recurved; lateral corolla lobes elliptic, subacute to obtuse, spreading; anterior corolla lobe elliptic to lanceolate, acute to obtuse, spreading. Stamen filaments coloured, inserted about middle of corolla tube, 1.0- 1.2 mm long; anthers pale yellow. Nectarial disk ciliate. Ovary globose to ellipsoid, emarginate, glabrous, 0.8 × 0.7 mm, 0.7 mm thick. Ovules 10- 20 per locule. Style 3.0-3.8 mm long, 0.17-0.2 mm thick, glabrous, pink to dark mauve. Stigma bilobed (sometimes 4-lobed), white to yellow at anthesis, 0.2-0.3 mm wide. Capsule turgid, truncate to emarginate, dark brown, 2.0-2.5 × 1.0-1.5 mm, 1.5 mm thick, glabrous. Loculicidal split of capsule extending 1/3-way to base. Seeds not seen.

Suffrutices parvi, ramunculosi; cortex crassus; a H. raoulii foliis angustioribus, ad medium latissimis, acutis, dentibus foliorum pluribus; pilis caulium inflorescentiarumque brevioribus; lobis calycis quatuor, liberis; corolla staminibus et stylis parvioribus, intensius coloratis; antheris pallidioribus; stigmate lobato, in alabastro incluso vel vix exserto differt.
