The systematic order of the plant world
In the Systematic Group, the plantings in the beds serve to reflect the family tree of angiosperms. In groups 1-19, the related species from the different plant families grow side by side, from the magnolias near the root of the family tree in groups 1-2 to the plants from the aster family at the top of the family tree in groups 17-18.
The angiosperms evolved from a common ancestor that lived at least 140 million years ago. Today, angiosperms are the most species-rich group in the entire plant kingdom – grasses, broadleaf trees and species with conspicuous flowers are all angiosperms. They differ from naked-seeded flowering plants such as conifers in their ovules, which are covered by carpels.
The plant display in the systematic group enables visitors to trace the evolutionary history of angiosperms.
