Sannantha bidwillii is a species in the myrtle family, Myrtaceae and is endemic to coastal Queensland in Australia. It is a shrub or tree with elliptic to egg-shaped leaves with the narrower end towards the base, and clusters of 3 white flowers.

Description

Sannantha bidwillii is a shrub or tree that typically grows to a height of up to 5 m (16 ft) and has scaly to fibrous bark. It leaves are elliptic to egg-shaped with the narrower end towards the base, 4.5–7.0 mm (0.18–0.28 in) long and 1.3–2.0 mm (0.051–0.079 in) wide on a petiole 0.6–1.0 mm (0.024–0.039 in) long. The flowers are arranged in leaf axils, usually in clusters of 3 on a peduncle 4.5–8 mm (0.18–0.31 in) long, each flower on a pedicel 3.0–4.5 mm (0.12–0.18 in) long with 2 linear bracts at the base, but that fall off as the flowers develop. The floral tube is 1.5–2.0 mm (0.059–0.079 in) long, the sepal lobes 0.4–2 mm (0.016–0.079 in) long. The petals are 2.2–2.6 mm (0.087–0.102 in) long and 2.0–2.5 mm (0.079–0.098 in) wide and there are usually 7 to 10 stamens. Flowering occurs from October to December and the fruit is a hemispherical, capsule 2.6–3.5 mm (0.10–0.14 in) in diameter.[2][3]

Taxonomy
