Definition
Pomaderris lanigera is a species of flowering shrub in the family Rhamnaceae, native to eastern Australia. It is commonly referred to as woolly pomaderris.
Overview
The species occurs in a range of habitats including open forest, woodland, and scrub, primarily in the states of New South Wales and Queensland, with isolated records in the Australian Capital Territory. It is an erect to spreading shrub that typically reaches heights of 1–2 m. The plant flowers from late winter to early spring, producing small, creamy‑white to pale yellowish inflorescences that lack petals but possess conspicuous, hairy sepals.
Etymology / Origin
The generic name Pomaderris is derived from Greek roots—pôma meaning “cover” and derma meaning “skin”—referring to the densely pubescent (hairy) covering of the leaves and stems. The specific epithet lanigera comes from Latin, where laniger means “wool‑bearing” or “covered with wool,” again alluding to the plant’s characteristic woolly indumentum. The exact historical rationale for the naming was provided in the original species description by Robert Brown (published by George Bentham, 1863).
Characteristics
| Feature | Description |
|---|---|
| Growth form | Shrub, erect to spreading, 1–2 m tall |
| Leaves | Alternate, narrowly elliptic to lanceolate, 20–60 mm long, 5–15 mm wide; both surfaces densely covered with fine, white to greyish hairs giving a woolly appearance; margins usually revolute |
| Stems | Young stems densely tomentose (woolly) with star‑shaped hairs |
| Inflorescence | Cymes or panicles 10–30 mm long; flowers lack true petals but have 5–6 sepals (2–3 mm) that are petaloid and hairy |
| Flowering period | Mainly August to October (southern hemisphere) |
| Fruit | Small, dry, indehiscent capsule containing a few seeds; capsules are covered with short hairs |
| Habitat | Well‑drained sandy or loamy soils, often on slopes or ridges; tolerates a range of moisture conditions but is most common in mesic environments |
| Conservation status | Not listed as threatened at the national level; considered locally common in much of its range |
