Alstonia constricta, commonly known as the Bitterbark or Bitterbark tree, is a species of small tree or shrub in the family Apocynaceae. It is native to Australia, specifically found in the regions of Queensland, New South Wales, and Northern Territory.
Description[edit | edit source]
Alstonia constricta typically grows to a height of 3 to 10 meters. The tree has a distinctive greyish-brown bark that is deeply furrowed. The leaves are arranged in whorls and are narrow, lance-shaped, and leathery. The flowers are small, white, and fragrant, appearing in clusters. The fruit is a long, slender follicle containing numerous seeds.
Habitat[edit | edit source]
This species is commonly found in woodland and open forest environments, often on sandy or rocky soils. It is well adapted to dry conditions and can often be found in areas with low rainfall.
Uses[edit | edit source]
Alstonia constricta has been traditionally used in Aboriginal Australian medicine. The bark contains alkaloids that have been used for their medicinal properties, particularly as a febrifuge and tonic. The bitter taste of the bark is due to these alkaloids.
Cultivation[edit | edit source]
The tree is not commonly cultivated but can be grown from seed. It prefers well-drained soils and a sunny position. It is relatively drought-tolerant once established.
Conservation Status[edit | edit source]
The conservation status of Alstonia constricta is not currently listed as threatened. However, habitat destruction and changes in land use could potentially impact local populations.
