Description

Eucalyptus preissiana, commonly known as bell-fruited mallee, is a species of small tree or shrub that occurs in an area between Albany and Esperance in Western Australia. It has a spreading habit, smooth bark, elliptical to egg-shaped or oblong leaves, flower buds in groups of three, yellow flowers and cup-shaped, conical or bell-shaped fruit. Eucalyptus preissiana is a mallee that typically grows to a height of 3–5 m (9.8–16.4 ft) with a sprawling habit, and forms a lignotuber. It has smooth, greyish and brown bark. Young plants and coppice regrowth have stems that are square in cross-section and elliptical to egg-shaped leaves that are the greyish green, 50–93 mm (2.0–3.7 in) long, 30–62 mm (1.2–2.4 in) wide and arranged in opposite pairs. Adult leaves are sometimes arranged alternately, the same shade of dull greyish green on both sides, elliptical to egg-shaped or oblong, 65–130 mm (2.6–5.1 in) long and 25–50 mm (0.98–1.97 in) wide on a petiole 10–40 mm (0.39–1.57 in) long. The flower buds are arranged in leaf axils on a flattened, unbranched peduncle 8–25 mm (0.31–0.98 in) long, the individual buds on pedicels 2–5 mm (0.079–0.197 in) long. Mature buds are oval, 15–26 mm (0.59–1.02 in) long and 13–18 mm (0.51–0.71 in) wide with a conical to rounded operculum. Flowering occurs from September to November and the flowers are yellow. The fruit is a woody, cup-shaped, conical or bell-shaped capsule 15–27 mm (0.59–1.06 in) long and 20–38 mm (0.79–1.50 in) wide with lobes between the valves. Bell-fruited mallee is found in coastal and sub-coastal areas among limestone and laterite and grows in gravelly sandy-clay soils. It occurs in coastal and near-coastal areas from the Stirling Range to the Fitzgerald River National Park and almost to Esperance to the east. Subspecies lobata only occurs in coastal areas in a few places between Esperance and Hopetoun. Subspecies preissiana is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife, but subspecies lobata is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife, meaning that is rare or near threatened.
