About
Eucalyptus bosistoana, commonly known as the coast grey box or Bosisto's box, is a tree that is endemic to south-eastern Australia. It has rough, flaky bark at the base of its trunk, smooth cream yellow or grey bark above and sometimes throughout, the smooth bark shed in ribbons. The adult leaves are lance-shaped to curved and the flower buds are arranged in groups of seven. The flowers are white and the fruit is a cup-shaped, barrel-shaped or hemispherical capsule.
Where it grows
Coast grey box occurs in New South Wales and Victoria from as far north as the Wolgan Valley, west of Sydney and as far south as eastern Gippsland. It is found near streams in lowland areas on better quality soils, particularly over limestone, although it may also appear on the tablelands up to 500 m (1,600 ft) above sea level, near Goulburn and Bungonia.
Uses
A significant timber species, resistant to termites though susceptible to lyctus borers. The interlocked grain timber is highly regarded for heavy engineering. Other uses include construction, piles, poles and sleepers. A durable timber of considerable weight, being 1100 kilograms per cubic metre.
