Alstonia constricta, known as quinine bush or bitterbark, is an Australian shrub or small tree that suckers from its roots to form thickets. It tolerates a wide range of conditions from humid coast to semiarid inland, and is mainly of interest for its medicinal alkaloids rather than as a garden plant.
Alstonia constricta, commonly known as quinine bush or bitterbark, is an Australian endemic shrub or small tree species of the family Apocynaceae.
Alstonia constricta is the only subtropical member of the genus, and occurs in Eastern Australia from the Tropic of Capricorn in Queensland and then southward to northern New South Wales. The species occurs in eucalypt and Acacia woodlands, vine scrubs and gallery forests from humid coastal regions through to the semiarid and arid inland. The field botanist Anders Bofeldt discovered an isolated population in the Shoalhaven River Gorge in southern New South Wales.
