| 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).
The mainly alpine genus Pappochroma were
previously considered to be species of Erigeron
