It has scaly to fibrous bark, narrowly lance-shaped to linear leaves and white flowers, and usually grows in forest on rocky hillsides.

Sannantha angusta is a shrub that typically grows to a height of up to 2.5 m (8 ft 2 in) and has scaly grey to fibrous bark.

[2][3] This species was first formally described in 1999 by Anthony Bean who gave it the name Babingtonia angusta in the journal Austrobaileya from specimens he collected near Coutts Crossing in 1995.
