It is a shrub or small tree with narrow lance-shaped adult leaves, groups of creamy white flowers and cylindrical follicles.

Stenocarpus angustifolius is a shrub or small tree that typically grows to a height of 4–5 m (13–16 ft) and has minutely hairy young branchlets that soon become glabrous.

[2] Stenocarpus angustifolius was first formally described in 1919 by Cyril Tenison White in the Botany Bulletin of the Department of Agriculture, Queensland from specimens collected near Stannary Hills by Thomas Lane Bancroft.
