Bottle tree is a succulent plant which can be
a thorny shrub grown in a pot, or can grow
into a small tree up to 6 m tall. The species name derives from the 19th
century Portuguese geologist Fernando da Costa Leal, who described the
Bottle tree during an exploration in southern Angola. The plant is
characterized by the thick bottle-shaped trunk, which is almost branchless
until the top. The branches are few and covered by slender thorns up to 30
cm long. Leaves are oblong and are covered with short hairs on both
surfaces. The flowers bloom in spring, when the tree is leafless. The
white flowers, characteristic of the Oleander family, cluster around the
tips of the branches. The Bottle tree is endemic to Namibia and southern
Angola where it grows in the semi-desert areas and dry rocky hillsides.
The plant produces a watery latex, rich in toxic alkaloids, used by local
populations as arrow poison for hunting. In contact with the eyes this
latex can produce blindness.
