Tasmania has eight native and two introduced species of Melaleuca (including the species previously known as Callistemon). These are trees or shrubs characterised by having sessile flowers with conspicuous stamens and inconspicuous petals. The flowers form bottlebrush like spikes (sometimes compressed and head-like) and develop into persistent woody, sessile capsules. The species often occur in boggy places, and often have papery bark.

Tasmania has one native and one introduced species of Kunzea. These are both large shrubs or trees. Like Melaleuca species, these plants have flowers in dense spikes, but the fruit is softer. The plants are quite strongly honey-scented when in flower.

Tasmania has one species of Thryptomene. It is a shrub with small flowers with conspicuous petals and few stamens. The fruit is soft.
