Alstoria spectabilis is a medium to tall tree (up to 40 meters tall) that ranges from
Sri Lanka, India, Mayalsia, southern China, and coastal northern Australia. It is used at the Weipa Bauxite Mine in northern
Astralia to replant previously mined landscapes.
It bears leathery leaves with small (3.5 to 5 mm) fragrant white flowers. The twigs produce
a milky alkaloid substance while the living bark is bitter when chewed. Aborignal people have used the bark for a variety
of medicinal purposes including relief of abdominal pain, fever, and dysentery. Common names include Jackapple, Bitterbark,
and Hard Milkwood.
