Characteristics

Multi-stemmed shrub to 2 m high; branchlets tomentose with ± spreading hairs. Stands displaying a range of early developmental stages in leaves. Leaves in juvenile stages subsessile, clustering around a spinescent short shoot to 10 mm long; lamina narrowly elliptic to narrowly obcordate, glabrous, margin entire, apex shortly mucronate. Later development stages with leaves barely petiolate (0.7 mm long); lamina 9.5–19 mm long, to 3 mm wide, glabrous, with thickened margins. Inflorescences are mostly axillary, solitary, white regular flowers, rarely 2–5-flowered racemes or terminal racemes to 30 mm long, barely pedicallate, the pedicel c. 1 mm long, elongating up to 8.5 mm in fruit, tomentose. Sepals 5, to 3.6 mm long, narrowly ovate, to 9 mm long, acute, spreading, white, glabrous. Stamens regularly inserted opposite sepals; filaments to 5 mm long, white; anthers elliptic, dehiscing through slits. Pistil with compressed ovary to 3 mm long, tapering to a style (1.5 mm), all glabrous. Fruit a compressed, subglobose to broadly cordiform capsule, 6–10 mm long, 6.5–11.2 mm wide, rounded or slightly emarginated apex, minutely transversely striate, glabrous, green ripening brown, persisting long after seed shed. Seeds compressed, ± ovoid, 3.5–3.7 mm long, c. 2.8 mm wide, slightly winged at margins, brown.

Environment

These populations inhabit Eucalyptus shrubby woodland on shallow, sandy soils derived fro sandstone of the Grafton formation, Kangaroo Creek sandstone and Malanganee Coal Measures. Dominant tree species at the type locality include Eucalyptus propinqua, E. fibrosa, Corymbia variegata with Allocasuarina littoralis and Acacia falcata in the understory (Telford 2013).
