Mondrian has broken the form of the branches down and simplified it into basic shapes. You can see the characteristic shape of the branches and would still possibly be able to identify the type from this however. The curves of the branches and the way they repeated is very pleasing. I love the monochrome nature of this painting as well.
I then did some research and found that he actually did a series of tree paintings and it's possible to see the way he has progressed through the stages of abstraction to his simple grid shapes that we are more familiar with. He seems to analyse the branches and then break them down into squares and regular shapes.
