Popular floras books to identify plants of a certain area sometimes group plants using color of their flowers, or their growth form trees, shrubs, herbs, and so on. Although such books are useful in finding the names of taxa, they provide few clues about relationships among the taxa and hence are not predictive, which means that you can deduce nothing more about the plant other than that it exhibits the characteristics used to classify it. That is, by enumerating the characteristics of a plant, one can predict the natural group to which it belongs. Taxonomic floras, for example, identify species, genera, and families by listing as many characteristics as possible concerning anatomy, morphology, cytology, ecology, biochemistry, genetics, and distribution.
