This is a real back-to-basics approach, both to the subject of drawing and to writing books on drawing.  Forget all those pages devoted to materials and tips, and the written descriptions of what you need to do, and look instead at a book filled with just diagrams.  Who needs words after all, to show how to draw pictures?  Every page shows you how, in about eight or nine staged steps, to paint a particular garden flower.  At the bottom is a finished tonal drawing in done in pencil, and one painted in watercolors.  In each of the drawings the previous stage is shown in a different color, so you can see what to do next.  It is surprisingly easy to do, although the huge leap from a simple pencil outline to the complex tonal or painted study is far from obvious, and I would have preferred fewer early stages and more showing the later nuances.
