Gaudium multicaule, commonly known as the silver tea-tree,[2] is a species of shrub that is endemic to south eastern Australia.

Gaudium multicaule is a shrub that typically grows to a height of 1.5 m (4 ft 11 in) and has smooth bark that is shed from the smaller stems in stringy strips.

The flowers are usually borne singly, sometimes in pairs on short side shoots, and are white or pink and 6–10 mm (0.24–0.39 in) wide.

Flowering mainly occurs from October to November and the fruit is a hemispherical capsule 3–3.5 mm (0.12–0.14 in) wide with the remains of the sepals attached, but which fall from the plant soon after the seeds are released.

[2][3][4] This species was first described in 1825 by Allan Cunningham who gave it the name Leptospermum multicaule in a Chapter entitled On the Botany of the Blue Mountains in Barron Field's book Geographical Memoirs on New South Wales.
