Low spreading shrub up to 1 m tall. Old stems grey-brown; branchlets yellowish brown, drying dark, glabrous or minutely puberulent when young; internodes 3–10x diameter. Leaf bud usually with small rounded sinus, sometimes sinus absent. Leaves erecto-patent to patent; lamina lanceolate to narrowly elliptic, coriaceous, glossy bronze green above, slightly duller beneath, (30–)50–100 × (7–)10–18(–28) mm, glabrous except for minute glands and short eglandular hairs on midrib above, young leaves sometimes ciliolate or minutely glandular along margins; apex subacute to acute; base abruptly narrowed to short ciliolate petiole; margin entire, glabrous, pale, weakly bevelled. Inflorescences lateral, racemose, 5–10(–15) cm long; flowers distant, spiralled. Peduncle and rachis with minute spreading eglandular hairs; peduncle 1–3 cm long. Bracts linear, acute, ciliolate, usually shorter than or equalling pedicels, rarely longer. Pedicels erecto-patent to spreading, 2.5–4 mm long. Flowers weakly turpentine-scented, protandrous. Calyx lobes broadly ovate, acuminate, overlapping at edges, 3 × 1 .5–2 mm; outer surface with scattered minute sessile glands; margin eglandular- and glandularciliolate. Corolla pale pinkish mauve, fading dirty white; tube 2.5–4 mm long, broad and rounded at base, puberulent inside; lobes suberect, ovate to lanceolate, subauriculate at base, acute, 4–5 × 2.5– 4 mm. Anthers pale mauve, acute, 2 .5 mm long; filaments pinkish mauve, fading white, 6–7 m m long, curving outwards after dehiscence. Nectarial disk glabrous, fleshy, dark green. Style white, glabrous, 6–7 mm long; stigma subcapitate. Ovary cylindrical, glabrous, 1–1.2 × 0.8 mm; ovules c . 8– 10 per locule, marginal on a discoid placenta. Capsule ovoid, acute, pale brown, 4.5–5(–6) × 3.5– 4 mm, septicidal to base, loculicidal to half-way. Seeds brown, elliptic to subcircular, strongly flattened, smooth, 2–2.5 × 1 .5–2 mm.

Spreading or trailing gynodioecious subshrub with ascending to erect branchlets, to 20 cm tall. Old stems grey or brown; branchlet s greenish to pale brown, with red band at nodes, bifariously pubescent; internodes 1–2x diameter. Leaf bud with narrow acuminate sinus. Leave s spreading, very shortly connate; lamina elliptic to obovate, subcoriaceous, yellowish green above and beneath, 3.5–9 × 2–5 mm, usually with sparse, very short, tapering eglandular hairs on midrib above an d beneath and margins, rarely glabrous; apex broadly rounded; base cuneately narrowed to short broad flat petiole; margin entire, yellowish, rounded. Inflorescences terminal, racemose, 1–3 cm long; flowers crowded, spiralled. Peduncle and rachis puberulent; peduncle very short. Bracts linear-lanceolate to narrow-elliptic, obtuse to acute, minutely ciliolate, slightly shorter than calyx lobes. Pedicels erecto-patent, 0.5–2 mm long. Flowers sweetly scented, female or hermaphrodite on separate plants. Calyx lobes 4, oblong to elliptic, obtuse to subacute, not overlapping, 2.5–3 × 1– 1.5 mm; margin minutely glandular and eglandular ciliolate. Corolla white; tube 1.5–2 × 1 .5–2 mm, funnelform, glabrous; lobes recurved, elliptic (female) to broadly elliptic (hermaphrodite), obtuse, 2.5–3 × 1.5–2.5 mm. Anthers purple, obtuse, fertile and c. 2 mm long (hermaphrodite) or sterile and c. 1 mm long (female); filaments white, long-exserted , 1(female)–3(hermaphrodite) mm long, erect or slightly spreading. Nectarial disk glabrous, fleshy, green. Style white, glabrous, (1–)3–5 mm long, curving to anterior of flower, clavate below stigma; stigma subcapitate. Ovary ovoid, glabrous, c. 1 × 0.7 mm; ovules 12–15 per locule, marginal on a discoid placenta. Capsule flattened, ovate, acute, dark brown, 3.5–4 × 3 mm, 1 mm thick, septicidal to base, loculicidal at apex only. Seeds pale orangebrown, elliptic, strongly piano-convex, smooth, 0.9– 1.1 × 0.6–0.8 mm. Chromosome number 2n = 42 (Hair 1967, as H. petriei var . petriei, now redetermined as H. murrellii).
