Phylogenetic relations between various groups of plants
The Engler System represents the most modern sector of the Garden, even though it dates back to the early twentieth century, when the Botanical Garden was interested in the acquisition of a piece of land, on the southern border where the municipal nursery once stood.
Plants are arranged according to the systematic scheme of the German botanist, of Polish origin, Adolf Engler, who studied the phylogenetic relations among the various groups of plants.
The collections are divided into Gymnosperms and Angiosperms, the latter urther classified into Dicotyledons and Monocotyledons. The layout follows a sequence from the least to the most evolutionarily advanced forms, in accordance with the phylogenetic tree of the various classes, orders and families.
This arrangement allows visitors to observe the defining characteristics and differences among plant groups, effectively walking through the evolutionary history of the plant kingdom in an open-air setting.
