#### How related are tree-species: Systematics

For your understanding of trees it might help to know some background on their relatedness. See also here and here for a different overview. You can see to a degree how close treespecies are related by the schema below:

##### The place of trees in the plant kingdom.

All trees are seed-plants. non-seedplants are the Pteridophyta with species like ferns.

##### Different groups containing trees in the plant kingdom.

Some trees are Gymnosperma (naked-seeds) like coniferes, pines and cypresses, lork and taxus.
All trees with leafs are Angiosperma, (flowering plants with covered-seeds), of the class dycotyla (seeds with two parts) as opposed to moncotyls (like grasses for example).

##### Relatedness of tree-species.

Trees with leafs can be more or less related. The ordes Salicales and fagalus are very related. Salicales are willows (wilgen) and cottonwoods (populieren). The order Fagalus contains the birches (berk) and alders (els) in one family, beech (beuk) chestnut (kastanje) and oak (eik) in another and elms (iep) in yet another. All these families of species are in close relationships to one another. These orders were amongst the first flowering plants to evolve about 140 million years ago.

Other trees that are related are those inside the order of Rosalia that contains the Platana (platanen) and Rosaceae with prunus (cherry kers), apple pear (appel en peer) and so on.
Also related are the maples (esdoorns) and horsechestnut (paardekastanje). The ash is part of the order that also contains the olive-tree. The Linden (linde) stand on their own.
