Description
[edit]Micromyrtus vernicosa is a spreading shrub that typically grows up to 2 m (6 ft 7 in) high and wide and has more or less drooping branchlets. It has overlapping, lance-shaped leaves with the narrower end towards the base, 1.5–2.5 mm (0.059–0.098 in) long, 0.5–0.6 mm (0.020–0.024 in) wide on a petiole 0.25 mm (0.0098 in) long. The leaves are glabrous and glossy with prominent oil glands. The flowers are 1.9–2.1 mm (0.075–0.083 in) wide and arranged singly in leaf axils on a peduncle 0.5–1.0 mm (0.020–0.039 in) long, with 2 translucent bracteoles about 0.7 mm (0.028 in) long at the base. There are 5 more or less round sepals lobes 0.3–0.4 mm (0.012–0.016 in) long and 0.5–0.6 mm (0.020–0.024 in) wide, and 5 white, elliptical petals 0.8–1.0 mm (0.031–0.039 in) long and 0.6–0.7 mm (0.024–0.028 in) wide. There are 5 stamens, the filaments about 0.4 mm (0.016 in) long and the style is 0.3 mm (0.012 in) long. Flowering has been observed in May and June.[2]
