Plant Systematics: A Phylogenetic Apoproach. 4th rev. ed. 2016. XVII, 677 p. 4to. Hardcover.

The 4th edition of Plant Systematics reflects changes in the circumscription of several families in order to represent monophyletic groups, following the classification of the Angiosperm Phylogeny Group (and recent phylogenetic analyses). Appendices cover botanical nomenclature as well as field and herbarium methodology. 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. Plant Systematics: A Phylogenetic Approach, Fourth Edition is appropriate for any course devoted to the systematics of angiosperms or vascular plants and, secondarily, for local flora courses. The text assumes no prerequisites other than introductory botany or biology.New to the Fourth Edition: Chapter 2, Methods and Principles of Biological Systematics, has been completely rewritten with information on molecular (DNA-based) systematics now fullyintegrateda change required by the increasing importance of molecular methods in the construction of phylogenetic hypotheses. The chapter includes updated and expanded coverage of maximum likelihood and Bayesian methods, algorithmic approaches to tree construction, along with parsimony methods, and new sections on mapping characters on trees and dating phylogenies. 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. Revisions include the breakup of the non-monophyletic Woodsiaceae,Portulacaceae, and Clusiaceae, the segregation of Cleomaceae and Capparaceae from Brassicaceae s.l, Cabombaceae from Nymphaeaceae, Nyssaceae from Cornaceae, and Viscaceae from Santalaceae s.l. In addition, Illiciaceae are included in Schisandraceae, Hydnoraceae and Lactoridaceae in Aristolochiaceae, Centrolepidaceae and Anarthriaceae in Restionaceae, Turneraceae in Passifloraceae, Zannichelliaceae inPotamogetonaceae, and Memecylaceae in Melastomataceae. Several familial clades are for the first time included in the book: Balsaminaceae, Chrysobalanaceae, Fouqui-eriaceae, Garryaceae, Goodeniaceae, Hypoxidaceae, Musaceae, Phrymaceae, Pittosporaceae, and Thymelaeaceae.
