Description

edit

Sannantha collina is a shrub that typically grows to a height of up to 3 m (9.8 ft) and has grey, scaly to fibrous bark. Its leaves are lance-shaped, 6.5–12.5 mm (0.26–0.49 in) long and 1.7–2.5 mm (0.067–0.098 in) wide on a petiole 0.6–1.3 mm (0.024–0.051 in) long. The flowers are up to 8 mm (0.31 in) in diameter and arranged in leaf axils in groups of 3 to 7 on a peduncle 5.0–9.5 mm (0.20–0.37 in) long. Each flower is on a pedicel 2.5–4.0 mm (0.098–0.157 in) long with 2 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 0.6 mm (0.024 in) long. The petals are white, 2.2–2.8 mm (0.087–0.110 in) long and wide and there are usually 8 to 11 stamens. Flowering mainly occurs between November and March and the fruit is a hemispherical capsule about 3 mm (0.12 in) in diameter.[2]

Taxonomy

edit

This species was first formally described in 1999 by Anthony Bean who gave it the name Babingtonia collina in the journal Austrobaileya from specimens collected on Karana Downs in 1995.[2][3] In 2007, Peter Gordon Wilson changed the name to Sannantha collina in Australian Systematic Botany.[4] The specific epithet (collina) means "relating to hills", referring to the usual habitat of this species.[2]

Distribution and habitat

edit

Sannantha collina grows in shrubland and forest in isolated populations mainly between Yandina in north-eastern Queensland and Dorrigo in north-eastern New South Wales.[2]
