features

The representatives of the Proteales are very different. What they have in common is seeds with little or no endosperm . The ovules are often atropic. The gynoeceum is not fused ( chorikarp ). The stamens show a noticeable apical extension of the connective. The flowers are often twofold.

Systematics

The proteales are fairly basal within the eudicotyledons within the covering plants . The togetherness of the three contained families was only recognized through molecular genetic studies, as they have few common features.

The order of the silver tree-like includes three families with a total of 82 genera and 1610 species:
