Its leaves are lance-shaped, 6.5–12.5 mm long and 1.7–2.5 mm wide on a petiole 0.6–1.3 mm long. The flowers are up to 8 mm in diameter and arranged in leaf axils in groups of 3 to 7 on a peduncle 5.0–9.5 mm long. Each flower is on a pedicel 2.5–4.0 mm long with 2 bracts at the base, but that fall off as the flowers develop. The floral tube is 1.5–2.0 mm long, the sepal lobes 0.6 mm long.

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. In 2007, Peter Gordon Wilson changed the name to Sannantha collina in Australian Systematic Botany. The specific epithet (collina) means "relating to hills", referring to the usual habitat of this species.

Distribution and habitat
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.
