This book maintains that higher plants manifest some degree of sexual selection, and it begins to build a framework that unifies many features of plant reproduction previously considered unrelated. Reviewing evidence for sexual selection in plants, the authors discuss possible male-female interactions, concluding with an extensive set of hypotheses for testing. Mechanisms that could be employed in sexual selection in plants include various cellular mechanisms, such as both nuclear and cytoplasmic genetics, B chromosomes, and paternal contributions to the zygote, as well as abortion, double fertilization, delayed fertilization, and certain forms of polyembryony. This study compares the consequences of these processes for the evolution of mate choice in "gymnosperms" and angiosperms.

This second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
