| Tasmania
has four introduced species of Fleabane (Erigeron).
These are common erect weeds of disturbed areas, roadsides
and urban areas.
The flower heads of three of these species are in
terminal panicles. The outer flowers of the heads have
tiny ligules (only about 1mm long).
The fourth species, E.
karvinskianus is quite different: it is almost
hairless and its flower heads are solitary and on long
peduncles (flower stems).
Species of the mainly alpine genus Pappochroma
were previously considered to be species of Erigeron
