If not, you'll dig deeper into the section on evergreens. A dichotomy is a choice between two options, so it's a manual binary calculator. If, in the above example, the answer is "No, there aren't leaves", the next question might be, "Are the needles grouped in clusters or are they spaced indidually?". For the sake of this experiement, let's assume they're in clusters. Once we find the right page, the next question may be, "How many needles are in each cluster?" The options may be 3 or 5. Depending on which option is true, the book will tell you that you're looking at either a white pine or a red pine.
