Dendrology is basically a science all about trees and other plants that have woody structures. It seems appropriate to have such a complicated science for a plant system that took a long time and a lot of effort to evolve into the structures that they are today. Trees have a long history, about three hundred and seventy million years in the making, so there is a lot to learn, and piece by piece the science of dendrology has put together an evolutionary pattern, one that we will likely see continue with new species come and older species die off. The tree is quite fascinating, so too is the science of dendrology if you look beyond it's complicated name and the simple appearance of a tree.
