Pilidiostigma tetramerum is a species of plant in the clove and eucalyptus family Myrtaceae. It is native to the Wet Tropics bioregion of Queensland, Australia.
Description
Pilidiostigma tetramerum is a shrub up to 4 m (13 ft) tall, or rarely a small tree. It usually begins to flower when about 2–3 m (6½–10 ft) tall. The leaves are arranged in opposite pairs on the twigs and measure up to 8 cm (3 in) long and 2.5 cm (1 in) wide. There are two intramarginal veins, and the lateral veins are somewhat obscured.[4][5]
Flowers are produced, either singly or in racemes, in the leaf axils. They have four white petals which are more or less circular in shape and measure about 2.5 mm (0.10 in) in diameter. The fruit is a dark red-purple or black berry, about 15 mm (0.6 in) long and 20 mm (0.8 in) wide.[4][5]
