Asterales

Asterales ( ) is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids).

Phelline is a genus of shrubs and the sole member of the family Phellinaceae, a family of flowering plants endemic to New Caledonia. It is placed in the order Asterales and is related to two other small plant families: Alseuosmiaceae and Argophyllaceae. It contains ten species.

Pentaphragma is a genus of flowering plants. Pentaphragma is the sole genus in Pentaphragmataceae, a family in the order Asterales. These species are fleshy herbs, with asymmetrical leaf blades. They are found in Southeast Asia. Pentaphragma is rayless, but eventually develops rays in at least one of the species studied. This is interpreted as related to secondary woodiness or upright habit within a predominantly herbaceous phylad. The vessel elements of Pentaphragma have features universally interpreted as primitive in dicotyledons: scalariform perforation plates with numerous bars; pit membr
