Eucalyptus piperita

Eucalyptus piperita, commonly known as Sydney peppermint or peppermint gum, is a medium to tall tree in the family Myrtaceae endemic to the central and northern coasts and adjacent tablelands of New South Wales, Australia, growing on sandstone-derived sandy soils in dry sclerophyll forest. The tree typically reaches 15 to 25 metres in height with a straight trunk clad in rough, fibrous, finely furrowed grey-brown 'peppermint' bark to the smaller branches, the smallest twigs being smooth. Juvenile leaves are opposite, lanceolate to elliptic, and dull green, while adult leaves are alternate, narrow-lanceolate to falcate, 7 to 15 centimetres long and 1.5 to 3 centimetres wide, glossy green on both sides, with conspicuous oil glands releasing a strong peppermint-like aroma when crushed. White flowers are borne in axillary umbels of 7 to 15, each on a slender pedicel from a club-shaped bud with a hemispherical operculum, flowering mainly in summer. Fruits are hemispherical to slightly pear-shaped capsules 5 to 8 millimetres across.
