This book is a unique and integrated account of the history of North American vegetation and paleoenvironments over the past 70 million years. It includes discussions of the modern plant communities, causal factors for environmental change, biotic response, and methodologies. The history reveals a North American vegetation that is vast, immensely complex, and dynamic.

Book Description
Vistas in Botany, Volume 4: Recent Researchers in Plant Taxonomy covers some of the more important general aspects of plant taxonomy. This volume is composed of seven chapters that link the practice and theory of taxonomy to plant geography, ecology, pollen anatomy, embryology, genetics, and cytology. The opening chapter outlines the views on plant taxonomy classification, the relevance of these views to biological classification, and some of the problems of classification in the non-taxonomic fields of ecology, soil science, and librarianship. The succeeding chapter presents the classification of the spores in higher plants, the cormophytes. This topic is followed by discussions on the embryological characters of taxonomic significance and the interrelations of plant taxonomy, phytogeography, and plant ecology. The final chapters consider the taxonomic preparation of flora and plant fossils. This book will prove useful to taxonomists, botanists, ecologists, and scientists and researchers in the allied fields of botany.

Book Description
This study reproduces one "Report of Meetings" & six "Bulletins" from the Committee on Common Problems of Genetics, Paleontology, & Systematics. This Committee operated as an administrative unit of the National Research Council, part of the U.S. Nat. Acad. of Science. It was launched in 1943, blossomed for two years, then served as a cornerstone for other cooperative projects. The Committee provided a crucial foothold for those seeking a synthetics view of evolution in 1940s America. These forgotten documents show the Committee at work: building coalitions, defining priorities, & negotiating a common vision. They also show factions within the Committee competing for the leadership of this emerging community. Photo.
