Eucalyptus coolabah

Eucalyptus coolabah, the coolibah, is a medium-sized to large tree in the myrtle family (Myrtaceae) typically growing to about 20 meters tall, with a broadly spreading crown. The trunk bears hard, fibrous to flaky grey bark mottled with whitish patches in its lower part, while the upper branches are smooth, powdery, and white to cream. Young stems are characteristically square in cross-section. Juvenile leaves are dull bluish, lance-shaped, 40 to 130 millimeters long and 5 to 30 millimeters wide; adult leaves are lanceolate to curved, the same dull blue-green on both surfaces, 80 to 170 millimeters long. Flower buds are arranged on branching inflorescences in the leaf axils, with groups of seven buds on each branch, and open to small white flowers in most months of the year. The fruit is a small, woody conical to hemispherical capsule only 2 to 4 millimeters long. The species occupies occasionally flooded heavy-soiled plains and the banks of intermittent streams and creeks across inland eastern Australia, including New South Wales, Queensland, the Northern Territory, South Australia, and Western Australia.
