Plant Systematics
A Phylogenetic Approach
Fourth Edition
Walter S. Judd, Christopher S. Campbell, Elizabeth A. Kellogg, Peter F. Stevens, and Michael J. Donoghue
- The authors follow a phylogenetic approach throughout (as opposed to a phenetic or evolutionary taxonomic/eclectic approach).
- The text is copiously illustrated, using in large part the informative analytical drawings developed as part of the Generic Flora of the Southeastern United States project.
New to this Edition:
- Chapter 2, Methods and Principles of Biological Systematics, has been completely rewritten with information on molecular (DNA-based) systematics now fully integrateda change required by the increasing importance of molecular methods in the construction of phylogenetic hypotheses.
- Sections on speciation and species concepts have been rewritten to incorporate extensive recent research on these topics.
- Extensive revisions to 13 families that have undergone significant changes in circumscription have been implemented, and several familial clades are for the first time included in the book.
- Higher-level phylogenetic relationships have been updated on the basis of recently published analyses, and these relationships are reflected in the authors use of names.
- Updates to all chapters and to nearly all cladograms take into account recent taxonomic methods and hypotheses. In addition, several new cladograms and figures have been added.
- A greatly expanded online Photo Gallery of Vascular Plants includes over 9,700 photographs illustrating the diagnostic characters and morphological diversity of each of the familial clades covered in the textbook. The photos also include taxa of both temperate and tropical distribution, economically important species, and examples of important anatomical characteristics.
