This chapter begins with a discussion of the problems involved in the use of common names for plants, as illustrated by a survey of such names for two related species of American spring-flowering perennials. It continues with a brief historical account of the events that led to the development and acceptance of Linnaeus's Binomial System of Nomenclature. The history of the development of a six-kingdom classification is presented, along with a list of the divisions and classes included in the kingdoms covered in this text. A dichotomous key to the kingdoms and divisions of organisms is provided. The chapter concludes with a brief discussion of cladistics.
