What to read after How to Draw Trees (Facsimile Reprint)?

Gregory Brown provides profiles of oak, elm, willow, apple, chestnut, and other trees for the artist who wishes to pursue trees as a subject. Brown begins with the basic elements: the branches, leaves, and trunk, then covers various species. He notes, "There are, of course, many kinds of trees, each having a distinct character of its own and much pleasure can be gained by learning to recognize them. You will also get to understand them better, which will be a great help to you when you start your drawing." This is a reprint of this 1943 title.
