These three
genera of trees or shrubs share the uniting feature of having their
flowers in spikes (in many species, forming "bottlebrushes", or in
some species being head like). 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 bottle-brush-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. |
