Melaleuca leucadendra, commonly known as weeping paperbark, long-leaved paperbark or white paperbark is a plant in the myrtle family, Myrtaceae and is widespread in northern Australia, Southeast Asia, New Guinea and the Torres Strait Islands. It is a tree, sometimes growing to more than 20 m (70 ft) with a trunk covered with thick, white, papery bark and weeping thinner branches. It has a long flowering season, can flower at almost any time of the year and is often grown as a tree in parks and on roadsides. It was the first melaleuca to be described and was described from a specimen growing in Indonesia.
Melaleuca leucadendra is a large tree, usually less than, but sometimes more than 20 m (70 ft) tall. Its thick bark is papery, usually white but also pinkish or cream and it has weeping branches. Its leaves and young branches are covered with fine, short, white hairs when young but become glabrous as they mature. The leaves are arranged alternately, 75–270 mm (3–10 in) long, 6.5–40 mm (0.3–2 in) wide, flat, narrow egg-shaped or lance-shaped and tapering to a point. The leaves have 5 (sometimes as many as 9) longitudinal veins and are often curved or sickle-shaped.
The flowers are cream, white or greenish-white and are arranged in spikes on the ends of branches which continue to grow after flowering, sometimes on the sides of branches or in the upper leaf axils. Each spike is up to 35 mm (1 in) in diameter, up to 80 mm (3 in) long and contains between 7 and 22 groups of flowers in threes. The petals are 3–4 mm (0.1–0.2 in) wide and fall off soon after the flower opens. The stamens are arranged in five bundles around the flower and each bundle contains 5 to 12 stamens. Flowering can occur at any time of the year and is followed by fruit which are woody capsules, 3.9–4.9 mm (0.15–0.19 in) long in loose clusters along the stems.
Melaleuca leucadendra was first formally described in 1762 by Carl Linnaeus in Species Plantarum as Myrtus leucadendra. Linnaeus used a description of the species written by Georg Eberhard Rumphius in 1741, before the modern system of classification was devised by Linnaeus. Rumphius had described a plant growing in what is now Indonesia. Later, Linnaeus realised that this species had little in common with other species in the genus Myrtus and described the genus Melaleuca to accommodate this species. Thus, Melaleuca leucadendra became the first melaleuca to be formally described. The description was published in 1767 in Mantissa plantarum. It follows that although nearly all melaeucas are found only in Australia, the first type specimen was from Indonesia.
