Description

Eucalyptus oraria is a mallee, rarely a tree or low shrub that typically grows to a height of 1–15 mm (0.039–0.591 in) and forms a lignotuber. It has smooth, greyish bark that is shed in strips, sometimes with rough, flaky bark on the base of the trunk. Young plants and coppice regrowth have dull green, egg-shaped to lance-shaped leaves that are 50–90 mm (2.0–3.5 in) long and 13–35 mm (0.51–1.38 in) wide. Adult leaves are the same shade of glossy green on both sides, lance-shaped, 65–100 mm (2.6–3.9 in) long and 8–23 mm (0.31–0.91 in) wide, tapering to a petiole 8–15 mm (0.31–0.59 in) long. The flower buds are arranged in leaf axils in groups of between nine and nineteen or more on an unbranched peduncle 5–15 mm (0.20–0.59 in) long, the individual buds on pedicels 1–3 mm (0.039–0.118 in) long. Mature buds are oval, 4–7 mm (0.16–0.28 in) long and 2–4 mm (0.079–0.157 in) wide with a rounded operculum. Flowering mainly occurs from August to October and the flowers are white. The fruit is a woody, barrel-shaped capsule with the valves below the level of the rim.[2][3][4]

Taxonomy and naming

Eucalyptus oraria was first formally described in 1962 by Lawrie Johnson from specimens he collected near Dongara in 1960. The specific epithet (oraria) is from the Latin orarius meaning "pertaining to the coast".[5]

Distribution and habitat

Ooragmandee grows in sand in coastal and near-coastal areas, often over limestone and is found from near Jurien Bay to near Kalbarri and on some nearby offshore islands.[2][3]
