Sprawling to ± decumbent, openly branched shrubs to 0.2 m high, spreading to 0.3 m, resprouting after fire; branchlets quite glabrous to sparsely simple-hairy when young; older stems decorticating in papery flakes and strips. Leaves spreading, scattered, glabrous or with sparse simple hairs mostly on the midrib beneath, obovate to elliptic, 10–15 mm long, 2–5 mm wide, entire or with a very few blunt teeth towards the apex, flat but the margins slightly thickened; apex obtuse. Flowers sessile, axillary, subtended by 3–6 dark dark brown, scarious, broadly ovate, obtuse, glabrous bracts to 3 mm long. Sepals ovate-attenuate, 7–8 mm long, quite glabrous or with few to many, appressed to ± spreading hairs to 1 mm long; midribs not prominent; outer sepals acute to somewhat acuminate; inner sepals similar to the outer in size, shape, apex and indumentum but broader; buds acute. Petals yellow, obovate, 9–10 mm long, emarginate. Stamens 22–27, in three groups between the carpels, free; filaments 3–3.5 mm long, not closely appressed to the gynoecium; anthers oblong to rectangular, 1.2–1.5 mm long, dehiscing by short, introrse, longitudinal slits near the apex. Staminodes absent. Carpels 3; ovaries globular, glabrous; styles excentrically spreading-erect from near the carpel apex, 2–2.5 mm long. Ovules 2 per carpel. Seeds not seen.

Notes. Glabrous (but sepal indumentum variable; but see McCutcheon) - H. commutata at same site - mroe erect, hairy youung leaves (at least), typical sepal indumentum. No reason to believe hybridisation.

McCutcheon 2000 has sparse hairs on leaves and stems; Davis 14023 has sparsely hairy sepals; KRT 5780 has quite hairy sepals; KRT5778 very few hairs towards apex.
