Description: Spreading dioecious shrub to 1.5 m high; branches quadrangular, usually with two pairs of ridges laterally (forming 'angles'), minutely and densely hairy.
Leaves sessile; petiole not differentiated; stipules up to 1 mm long, soon reduced to a scarious scar; lamina subcoriaceous, linear, 7–30 mm long, 1–2.5 mm wide, juvenile leaves or leaves of young plants up to 6 mm wide [length to width ratio (5-)7–12]; base slightly narrowed, decurrent; margin entire, strongly recurved, such that lower surface hidden; lower surface densely, minutely papillose (margin and midrib glabrous, lacking papillae); upper surface glabrous.
Inflorescence axillary, metabotryoidal or botryoidal (variously reduced), usually 3–9-flowered (male), (1-)3-flowered (female); flowers unisexual, very shortly pedicellate; bracteoles 0.5–0.8 mm long. Corolla white or cream-coloured, c. 2 mm long; tube glabrous; lobes with outer surface glabrous, inner surface minutely papillose (papillae < 0.03 mm long). Stamens inserted c. ½ way up tube. Pistil 0.5–0.7 mm long (male), 0.7–1 mm long (female); ovary and style glabrous; stigma clavate (male), ovoid-capitate, ± bilobed (female).
Capsule slightly flattened, ± ellipsoid to ± cylindrical, 3–5.5 mm long, 2–2.5 mm diameter, with style and stigma persisting for some time; seeds few per locule, fawn-coloured, slightly flattened-obloid, 1.8–2.2 mm long, c. 1 mm wide, minutely papillose.
Distribution and occurrence: This species extends from Booroomba Rocks (Australian Capital Territory) south through Kosciuszko National Park in New South Wales, to Mt Buffalo and Mt Tingaringy in Victoria. grows in heathland communities, in Kunzea ericoides-K. muelleri dominated shrublands or in subalpine eucalypt woodlands (dominated by Eucalytus pauciflora, E. stellulata or E. niphophila). It grows on rocky slopes or exposed hilltops in skeletal soils derived from a granitic substrate at high elevations (1200-1450 m).
NSW subdivisions: SC, CT, ST
Other Australian states: Vic.
despite the limited number of known populations and the disjunction between each of these populations, this species is not considered to be at risk.
