Araliaceae

The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants commonly called the ivy or ginseng family. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels.

There are numerous plants of economic importance. Some genera, such as Hedera (the ivies), Fatsia (Japanese aralias) and Heptapleurum (formerly Schefflera, the umbrella trees), are used as ornamental foliage plants. The family also includes Panax ginseng, the root of which is ginseng, used in traditional Chinese medicine.

The morphology of Araliaceae varies widely. Many studies have found that there is no unifying characteristic capable of classifying the family. In general, Araliaceae species have large, usually alternate leaves, often with aromatic ethereal oils, five-petaled flowers, two to five carpels, simple umbels, and berries without carpophores or oil cavities. Some taxa carry prickles, and the family is often woody but also occasionally herbaceous. While Araliaceae is predominantly a tropical family, some taxa are also endemic to temperate climates. They are found in the Americas, Eurasia, Africa, Australia, New Zealand, New Caledonia, and Pacific islands.[citation needed]

Some examples of Araliaceae include the angelica tree (Aralia spinosa), the devil's club (Oplopanax horridus), ivy (Hedera spp., including H. helix), and herbs such as ginseng (Panax spp.). Leaves are sometimes lauroid (resembling Laurus) and are simple to compound; when compound, they are ternate, pinnate, or palmate.[citation needed]

Araliaceae are found in the pluvial montane forest, very humid montane forest, and humid lowland river forest regions. They are also present in laurel forest, cloud forest, and warm, humid habitats.[citation needed]

Araliaceae is one of six angiosperm families recognized by APG IV belonging to the Apiales, an order within the Asterids. Araliaceae is accepted to be a monophyletic branch within the Apiales.

Within Araliaceae, there are four accepted groups:

1. The Greater Raukaua group, sister to the rest of the main Araliaceae clades.
