'Tree' would be at the top of the hierarchy (or the root, if you think of a hierarchy as a tree!). You can then set up 'trees' as a synonym, and 'plane', 'willow', 'eucalyptus' and so on as 'children' (perhaps with their Latin names as synonyms). If you know you've photographed a plane tree then by definition it is a tree and will show up in searches for 'tree' - you don't have to type 'plane', 'platana' or 'tree' into the keywords for each of the thousand pictures you've taken of plane trees. If you don't know what kind of tree you've photographed you can just keyword it as 'tree'. Of course, where it all goes horribly wrong is that a plane is also a woodworking tool, a flat level surface and a means of transport, none of which is a subset of tree.
