Micromyrtus racemosa

Micromyrtus racemosa is species of the flowering plant in the family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with relatively thick, narrowly egg-shaped leaves, sometimes with the narrower end toward the base, and white, cream-coloured or yellow flowers 2.5–4.0 mm in diameter.

Description
Micromyrtus racemosa is a shrub that typically grows to 0.7–3 m high and 0.1–1.5 m wide and has erect leaves, sometimes almost pressed against the stems of smaller branchlets. Its leaves are narrowly egg-shaped, sometimes with the narrower end towards the base, 1.5–4.0 mm long, 0.5–0.8 mm wide and 0.3–0.4 mm thick, on a petiole 0.3–0.6 mm long. The flowers are 2.5–4.0 mm in diameter, and arranged in between 4 and 20 upper leaf axils on a peduncle 1.3–3.0 mm long. The sepals are 0.1–0.35 mm long and 0.35–0.6 mm wide and the petals are white or cream-coloured, rarely pink, 1.1–1.6 mm long. The anthers are 0.30–0.35 mm long and the style is 0.15–0.35 mm wide. Flowering occurs between May and September and the fruit is 1.5–2 mm long and about 0.7–1.0 mm wide, containing a seed 1.4–1.8 mm long.

Taxonomy
Micromyrtus racemosa was first formally described in 1867 by George Bentham in his Flora Australiensis. The specific epithet (racemosa) means "racemose".
