Melaleuca alternifolia, commonly known as narrow-leaved paperbark, narrow-leaved tea-tree, narrow-leaved ti-tree, or snow-in-summer, is a species of tree or tall shrub in the myrtle family Myrtaceae. Native to Australia, it occurs in southeast Queensland and the north coast and adjacent ranges of New South Wales. It grows along streams and on swampy flats, and is often the dominant species where it occurs.
Melaleuca alternifolia is a small tree to about 7 metres (23 ft) with a bushy crown and whitish, papery bark. Leaves are linear, 10–35 millimetres (0.39–1.38 in) long and 1 millimetre (0.039 in) wide, smooth and soft. They are also rich in oil with the glands prominent.
Flowers occur in fluffy white masses of spikes 3–5 centimetres (1.2–2.0 in) long over a short period, mostly spring to early summer. The small woody, cup-shaped fruit, 2–3 millimetres (0.079–0.118 in) in diameter are scattered along the branches.
Taxonomy and naming
Melaleuca alternifolia was originally described in 1905 by Joseph Maiden and Ernst Betche as Melaleuca linariifolia var. alternifolia. It was renamed Melaleuca alternifolia in 1925 by Edwin Cheel. The specific epithet (alternifolia) is a botanical term meaning "having leaves that alternate on each side of a stem".
Distribution and habitat
This species grows well in a wide range of soils and climates. It prefers well-drained but most soils and a to be grown in fun sun.
The indigenous Bundjalung people of eastern Australia use "tea trees" as a traditional medicine by inhaling the oils from the crushed leaves to treat coughs and colds. They also sprinkle leaves on wounds, after which a poultice is applied. In addition, tea tree leaves are soaked to make an infusion to treat sore throats or skin ailments.
