Homoranthus decasetus is a plant in the myrtle family Myrtaceae and is endemic to a small area in central Queensland. It has small, thin leaves and flowers that fade to purple as they age.
Description
Homoranthus decasetus is an upright shrub that typically grows to a height of 2 m (6 ft 7 in). The leaves are arranged in opposite pair and are club-shaped, curved, circular in cross-section, up to 12 mm (0.47 in) long and about 1 mm (0.039 in) wide. The flower are arranged singly on short branchlets in leaf axils. The flower buds have bracteoles up to 3 mm (0.12 in) long at their base and that fall off as the flower develops. The calyx tube is urn-shaped, with five ribs on the outside. Each of the five sepals has two bristles up to 4 mm (0.16 in) long on its tip. The petals are round, about 2 mm (0.079 in) in diameter and ten stamens alternate with ten staminodes that are attached to the base of the calyx. As the flowers age they turn from white to red or purple. The fruit is about the same size as the flower and contains a single winged seed. Flowering and fruiting occur sporadically throughout the year.
