Eucalyptus squamosa
Eucalyptus squamosa, commonly known as scaly bark, is a species of small to medium-sized tree that is endemic to the Sydney region in New South Wales. It has rough, tessellated, fibrous or flaky bark, lance-shaped or curved adult leaves, flower buds in groups of seven, nine or eleven, white flowers and cup-shaped or hemispherical fruit. Description 
Eucalyptus squamosa is a tree that typically grows to a height of  and forms a lignotuber. It has rough,  grey or reddish brown, tessellated fibrous or flaky bark on the trunk and branches. Young plants and coppice regrowth have dull green to greyish, egg-shaped leaves that are  long and  wide and petiolate. Adult leaves are arranged alternately, the same shade of green to greyish on both sides, lance-shaped to curved,  long and  wide, tapering to a petiole  long. The flower buds are arranged in leaf axils in groups of seven, nine or eleven on paired peduncles  long, the individual buds on pedicels  long. Mature buds are oval,  long and  wide with a conical to beaked operculum. Flowering occurs from October to December and the flowers are white. The fruit is a woody cup-shaped or hemispherical capsule  long and  wide with the valves protruding strongly. Taxonomy and naming
Eucalyptus squamosa was first formally described in 1898 by Joseph Maiden and Henry Deane in Proceedings of the Linnean Society of New South Wales. The specific epithet (squamosa) is from the Latin word squamosus, meaning "scaly", referring to the bark of this species. Distribution and habitat
Scaly bark grows in sclerophyll woodland, where soil accumulates in depressions on the sandstone on and around sandstone plateaus, often on lateritic soils. It occurs in the Sydney region, between the Putty and Broke districts and the Royal National Park. References
