context_page_description: Nauclea orientalis is a species of tree in the family Rubiaceae, native to Southeast Asia, New Guinea, and Australia. It has many common names, including bur tree, canary wood, Leichhardt pine and yellow cheesewood. It grows to a maximum of around 30 m in height and has large glossy leaves. It bears spherical clusters of fragrant flowers that develop into golf ball-sized edible but bitter fruits. The yellowish to orange soft wood is also used for timber and in woodcarving and folk medicine.
context_section_description: Leichhardt trees usually grow near bodies of water, as they prefer alluvial soils. They can occur from shrublands of rheophytes, in areas often subjected to flooding, to rainforests where they flourish best. Leichhardt trees are pioneer species, settling areas leading to ecological succession. In Australia, they are usually associated in ecosystems including red gums and honey myrtles in drier habitats. In wetter areas they are associated with brush cherries, Moreton Bay chestnuts, and blush walnuts. They grow along with honey myrtles in swamps. In the Philippines, Leichhardt trees are usually found growing in secondary forests.
  Leichhardt trees grow at elevations of 0 to 500 m (0 to 1,640 ft) above sea level. Their native range extends from tropical Northern Australia and New Guinea to Southeast Asia; from the Philippines to Myanmar and Thailand (the biogeographic region of Malesia). They are the only species of Nauclea occurring in Australia, though in some regions they can be easily confused with species from the genus Neolamarckia (=Acanthocephalus).
