Definition of melaleuca in English:



  • An Australian shrub or tree that bears spikes of flowers. Some kinds are a source of timber or medicinal oil.

    • ‘Callistemons and melaleucas are often tricky to tell apart as they are both evergreen trees or shrubs with papery trunks.’
    • ‘A mature melaleuca tree can produce as many as 60 million seeds every year.’
    • ‘This species has the potential to threaten natural areas to a greater degree than melaleuca, an aggressive Australian tree that has largely been controlled within the Preserve.’
    • ‘A dozen native trees will be saved, including melaleucas, coolamons, conifers, a flame tree and a lilly pilly.’
    • ‘Acacias, grevilleas and melaleucas need careful annual pruning to keep them busy and attractive and should be replaced when they are no longer so.’


Modern Latin: from Greek melas ‘black’ + leukos ‘white’ (because of the fire-blackened white bark of some Asian species).
