'''Austrobaileyales''' is an order of [[flowering plants]], consisting of about 100{{r|palmer}} species of [[woody plant]]s 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.<ref>Angiosperm Phylogeny: A Framework for Studies of Genome Evolution, Plant Genome Diversity Volume 2, pp. 1–11, 2013, Springer, Pamela S.

== In different classifications ==
 
Until the early 21st century, the order was only rarely recognised by [[list of systems of plant taxonomy|systems of classification]] (an exception is the [[Reveal system]]).
 
 
 
The [[APG system]], of 1998, did not recognize such an order. The [[APG II system]], of 2003, does accept this order and places it among the basal angiosperms, that is: it does not belong to any further clade. APG II uses this circumscription:
 
 
 
* order Austrobaileyales
 
** family [[Austrobaileyaceae]], one species of [[woody plant|woody]] [[vine]]s from [[Australia]]
 
** family [[Schisandraceae]] [+ family [[Illiciaceae]]], several dozen species of [[woody plant]]s, found in [[tropical]] to [[temperate]] regions of [[East Asia|East]] and [[Southeast Asia]] and the [[Caribbean]].
 
** family [[Trimeniaceae]], half-a-dozen species, of [[woody plant]]s found in [[subtropical]] to [[tropical]] [[Southeast Asia]], eastern [[Australia]] and the [[Pacific Islands]]
 
 
 
Note: "+ ..." = optional seggregrate family, that may be split off from the preceding family. The [[Cronquist system]], of 1981, also placed the  plants in families Illiciaceae and Schisandraceae together, but as separate families, united at the [[rank (botany)|rank]] of order, in the order Illiciales.
