The
daisies (Asteraceae) include three alpine cushion plants, Abrotanella forsterioides, Ewartia meredithiae
and Pterygopappus lawrencii. The family is one of Tasmania's most
diverse and widespread families, including many native
herbs shrubs and trees, as well as many naturalised
herbs and shrubs. They occur in almost all habitats. They are
especially prominent in alpine areas, in grasslands and as weeds.
The inflorescence is distinctive, and is why Asteraceae
was once referred to as Compositae. The flowers are in compact heads
that often look like flowers. Bracts called phyllaries surround the
heads. The corolla has two forms
- tube flowers (elongate, radially symmetrical tubes with short lobes)
or ray flowers (short tubes with one side elongated). Species may
have only tube flowers (e.g. Chrysocephalum), only ray flowers
(e.g. Cichorium) or both (e.g. Erigeron). The phyllaries resemble ray
flowers (e.g. Bracteantha).
