The systematic garden shows the main groups in the plant kingdom. It was first laid out in 2005: a series of five beds treating the first major steps in the evolution of plants, followed by 27 beds illustrating the evolution of the flowering plants (angiosperms).
Molecular characters have had an enormous impact on the taxonomy of all living creatures. The Tree of Life website shows the latest ideas about the large groups recognized nowadays, see http://tolweb.org/tree/
The oldest groups in the first beds, and at the end of the series the groups that were split off most recently. In 2016, a team of specialists, the Angiosperm Phylogeny Group, published their fourth version of the taxonomy of the flowering plants. This changed the position and composition of several orders, so that an update required the move of many plants. On the 13th of October 2017 the new systematic garden was opened, when the new information panels were ready. With each bed there are now four types of information on offer: scientific information, both in Dutch and English, information for the general public, and a panel especially designed for children.
Each panel with scientific information features a cladogram, a diagram of the relationships between groups of plants. In each of the beds 1-27, next to the Dutch text, the cladogram featuring all 46 orders of flowering plants is shown – of the 416 flowering plant families, a cladogram of those families belonging in each bed is shown next to the English text.
Recently the poster featuring the cladogram of angiosperms has been published. You may download this poster plus background information by way of the following link http://www.plantgateway.com/poster/
The authors, James Byng and Maarten Christenhusz, allowed us to use this information before it was published, during the rearrangement of the systematic garden in 2017.
