Austrobaileyales is an order of
flowering plants, consisting of about 100 species of
woody plants growing as trees, shrubs and lianas. Perhaps the most familiar species is
Illicium verum, from which comes the spice
star anise. The order belongs to the group of
basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the
Amborellales and
Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade. The order includes just three families of flowering plants, the Austrobaileyaceae, a
monotypic family containing the sole genus,
Austrobaileya scandens, a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing
essential oils, and the Trimeniaceae, essential oil-bearing trees and lianas.
