Gaudium parvifolium, commonly known as lemon-scented tea-tree,[2] is a species of shrub that is endemic to eastern Australia.

It has thin, rough bark, egg-shaped leaves with the narrower end towards the base, white or pink flowers, and fruit with the remains of the sepals attached but that is shed when the seeds are mature.

The plant first appeared in scientific literature in 1797, in the Transactions of the Linnean Society of London published by the eminent 18th century botanist James Edward Smith.

[6][7] In 2023, Peter Gordon Wilson transferred the species to the genus Gaudium as G. parvifolium in the journal Taxon.

[3] Gaudium parvifolium grows in dry sclerophyll forest on shallow soils, especially in sandy and rocky areas.
