Erect, openly-branched to dense shrubs to 0.5(–0.7) m high; young branchlets mostly glabrous except for a minute, white pubescence of multi-armed hairs on the very youngest shoots near the leaf bases, with obscure tufts of short hairs in the leaf axils. Leaves spreading, scattered, linear, (12–)15–18(–20) mm long, c. 1 mm wide, the margins revolute and tightly abutting the rather weak midrib (which is usually sunken relative to the margins) or to each other, the abaxial surface obscured; adaxial surface smooth to obscurely tuberculate, glabrous when mature (or sometimes with sparse, minute, antrorse hairs from the tubercles) except for short hairs at the very base, the very youngest leaves sometimes with few, scattered hooked hairs that are soon deciduous; abaxial midrib smooth except for minutely papillate margins that grade into a dense but minute pubescence on the abaxial lamina (which is almost or completely hidden within the lacunae formed between the margins and the midrib and usually requires dissection to examine); petiole abaxially glabrous; apex tapering and pungent-pointed. Flowers pedicellate, from upper leaf nodes or on lateral shoots, the pedicels 6–15 mm long, glabrous or with sparse, minute, stellate hairs below the flower; bract 1, subtending the flower at the apex of the pedicel, linear to narrowly triangular, herbaceous, 1.6–3.5 mm long, abaxially glabrous, adaxially and on the margins minutely pubescent. Sepals ovate-acute, 3.8–5.5 mm long, herbaceous, with scattered hooked hairs mostly towards the base; midribs prominent especially at the base; outer and inner sepals similar in size and shape but the inner slightly broader, scarious-margined, and with minute stellate hairs where overlapped by the outer in bud. Petals 5, yellow, broadly obovate, 6–8.5 mm long, deeply emarginate. Stamens 10, all on one side of the gynoecium and curving over it like a hand of bananas; filaments 0.4–0.6 mm long, fused at the base into a robust claw; anthers rectangular, 1.5–2.2 mm long, dehiscing by introrse, longitudinal slits. Staminodes 2(3) either side of the stamens, sometimes also with a few behind the stamens. Carpels 2; ovaries globular, densely pubescent; styles inserted excentrically on the carpel apex, parallel and curved beneath the stamens, 1–1.8 mm long. Ovules 2 per carpel. Fruiting carpels and seeds not seen.
