Austrobaileyales
order of plants
Austrobaileyales is an order of flowering plants consisting of about 100 species of woody plants growing as trees, shrubs and lianas. A well known example is Illicium verum, commonly known as star anise. The order belongs to the group of basal angiosperms, the ANA grade (Amborellales, Nymphaeales, and Austrobaileyales), which diverged earlier from the remaining flowering plants. Austrobaileyales is sister to all remaining extant angiosperms outside 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.
In different classifications
Until the early 21st century, the order was only rarely recognised by 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 vines from Australia
family Schisandraceae [+ family Illiciaceae], several dozen species of woody plants, found in tropical to temperate regions of East and Southeast Asia and the Caribbean. The best known of those is Star anise.
The public source identifies “Austrobaileyales” as order of plants. This brief keeps that definition visible, then builds a research path around Austrobaileyales, order and plants.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Austrobaileyales”, the useful work is to connect “order of plants” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 2, 2026. The linked authority identifier is Q21788. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1998 and 2003.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
