A genus of 4 species of aromatic evergreen trees in the Myrtaceae family native to Australia and New Guinea. Of the four species, the most commonly cultivated is L. confertus, known as the box brush or brush box in Australia, where it is often grown as a street tree due to its pest and disease resistance, tolerance to drought, smog and poor drainage and little requirement for upkeep. Flowers are showy and unusual in appearance, with 5 elongated clusters of stamens radiating from the centre where petals usually are in classic flower structures, cream-white in colour, tending towards yellow at the throat. Foliage is leathery and lanceolate, with pointed tips.
