}}Tristania is a monotypic genus of flowering plants native to New South Wales, Australia, closely related to Thaleropia.[2] The genus had a number of species, but some have been reclassified as Lophostemon and Tristaniopsis. The sole species currently in the genus is Tristania neriifolia. It is known commonly as the water gum.[3] It is a small tree, with dense branching. The leaves are evergreen, opposite, simple, lanceolate, 5–9 cm long and 1 cm broad. The flowers are produced in dense clusters of 3–15 together; each flower is 1–1.5 cm diameter, with five small yellow petals and numerous conspicuous stamens.
