Micromyrtus greeniana

Micromyrtus greeniana is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to a small area in the west of Western Australia. It is a spindly shrub with linear to egg-shaped leaves and small white or cream-coloured flowers.

Description
Micromyrtus greeniana is a spindly shrub that typically grows to a height of 0.4–1.7 m with most of its leaves densely arranged on smaller side-branches. Its leaves are linear to egg-shaped with the narrower end towards the base, 5–6 mm long and 0.5–0.8 mm wide on a petiole 0.4–0.6 mm long, with obscure oil glands. The flowers are 4.0–4.5 mm in diameter, and arranged in 5 to 10 upper leaf axils on a peduncle 2.5–3 mm long with narrowly egg-shaped bracteoles about 2 mm long at the base. The sepals are broadly egg-shaped, 0.5–0.7 mm long and 0.7–0.9 mm wide. The petals are white or cream-coloured, 2.0–2.5 mm long. Flowering occurs from August to October and the fruits are 2.5–2.7 mm long and about 1 mm wide.
