Woolly gum

Eucalyptus pilularis, commonly known as blackbutt, is a tall, straight-trunked forest tree in the family Myrtaceae endemic to coastal and near-coastal eastern Australia, from southeastern Queensland to eastern Victoria. Mature trees reach 30-70 m in height with a single, cylindrical bole that is characteristically clothed in rough, fibrous, dark grey to blackish bark on the lower half and smooth, pale grey to creamy white shedding bark above, giving the species its common name. Adult leaves are lanceolate, glossy green, and slightly curved. Small white flowers are borne in seven- to eleven-flowered axillary umbels through summer, followed by hemispherical to slightly conical fruits 6-10 mm wide with valves enclosed within the rim. Blackbutt is one of the most important commercial hardwood timbers of New South Wales, valued for its strength, durability, and pale, attractive grain in flooring and construction.
