Description

Erect or scrambling shrub to 1.3 m, grey-green. Branches sparsely to moderately scabrous-tomentose with dendritic and forked, non-glandular hairs and scattered glandular hairs.

Leaves broadly elliptic to broadly ovate, rarely elliptic, almost sessile, mostly 3–7 mm long, 2–4 mm wide, sometimes larger, tomentose.

Flowers solitary or in 1–3–flowered cymes; pedicels 3.5–10 mm long. Calyx 1.5–2.5 mm long, glabrous. Corolla 6.5–11.5 mm long, almost glabrous, creamy-white, often tinged with yellowish-green, the striations purple; lobes linear, 3–6.5 mm long. Stamens 1.5–2 mm long.

Distribution and ecology

An uncommon species endemic in the Blue Mtns of N.S.W. Occurs as small, scattered populations in dry to wet sclerophyll forest, in sandstone soil.

Selected specimens

N.S.W.: Nepean River district, Sept. 1897, W. Forsyth (AD, NSW); c. 80 km NW of Sydney, L. Haegi 1416 (BRI, MEL, NSW).

Derivation of epithet

From scaber, rough or scabrous; the addition of -ellus indicates the diminutive and hence the plant is only somewhat scabrous.
