Description

Micromyrtus hexamera is a slender shrub that typically grows up to 2 m (6 ft 7 in) high and has many drooping branches. Its leaves are egg-shaped with the narrower end towards the base, 1.1–1.9 mm (0.043–0.075 in) long, 0.8–1 mm (0.031–0.039 in) wide and sessile or on a petiole up to 0.2 mm (0.0079 in) long. The leaves are glabrous and have a few prominent oil glands. The flowers are 5–6 mm (0.20–0.24 in) wide and arranged singly in leaf axils on a peduncle 0.7–1.2 mm (0.028–0.047 in) long, with 2 bracteoles about 1 mm (0.039 in) long at the base. There are 6 more or less round sepals 0.6–0.7 mm (0.024–0.028 in) long, and 6 more or less round white to pink petals 1.7–2.1 mm (0.067–0.083 in) long and wide. There are 12 stamens, the filaments about 1.0 mm (0.039 in) long. Flowering has been recorded in most months, with a peak in August and September, and the fruit contains a single seed. [2] [3] [4]
