It has thin, rough bark on the older stems, narrow egg-shaped leaves, relatively large white flowers and flat topped fruit that is shed shortly after reaching maturity.

Flowering mainly occurs from August to October and the fruit is a capsule 7–8 mm (0.28–0.31 in) wide with the remains of the sepals initially attached.

[3][4][5][6] This teatree was first formally described in 1788 by Joseph Gaertner who gave it the name Fabricia laevigata and published the description in his book De Fructibus et Seminibus Plantarum.

[7] In 2023, Peter Gordon Wilson transferred the species to the genus Gaudium as G. laevigatum in the journal Taxon.

It is useful as a windbreak or hedging plant and for the rapid stabilisation of sandy soils, and in rehabilitation areas where construction or mining has taken place.
