木兰藤目目

分类

以前的分类学家很少承认有这样一个目，即使第一版的APG 分类法也没有这一个目，但在2003年修订的APG II 分类法中列入了这个目，属于原始被子植物类。包括三个科：

• 木兰藤科 Austrobaileyaceae
• 五味子科 Schisandraceae
• 苞被木科 Trimeniaceae

本目在APG II 分类法中可包含八角茴香科 Illiciaceae，在APG III 分类法中此科被并入五味子科。

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.

family Trimeniaceae, half-a-dozen species of woody plants found in subtropical to tropical Southeast Asia, eastern Australia and the Pacific Islands

Note: "+..."=optional segregate 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 of order, in the order Illiciales.
