Description
editSannantha 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
editThis species was by first formally described in 1999 Anthony Bean who gave it the name Babingtonia virgata in the journal Austrobaileya from specimens he collected in the Yurol State Forest near Cooroy in 1993.[3][4] In 2007, Peter Gordon Wilson changed the name to Sannantha bidwillii in Australian Systematic Botany.[5] The specific epithet (bidwillii) honours John Carne Bidwill, who collected the first known specimen of this species.[3]
Distribution and habitat
editSannantha bidwillii grows in eucalypt forest in coastal lowland between Shoalwater Bay and Brisbane in Queensland.[3]
