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.

The Term Systematic Botany Encompasses The Domain Not Only Of The Higher Plants, But Also Of The Lower Plants. Since It Is Not Possible To Treat Adequately The Various Plant-Groups Under A Single Volume, This Edition Is Restricted To A Discussion Of The Angiosperms. It Has Been Designed As A Textbook For The Undergraduate Students (Pass & Honours) Of All The Indian Universities And It Will Be Helpful To Postgraduate Students In Botany As Well As To The Study Of Agriculture And Allied Subjects. The Author Has Abandoned Bentham-Hookers System And Presented A New Scheme Of Angiosperm-Classification. Although The Latter Scheme, Like Any Other Envisaged Before, Has Its Shortcomings, It Represents The Most Probable Natural Relationship Among Flowering Plants.Almost All The Taxa Prevalent In The Indian Flora Have Been Dealt With, Covering 44 Orders And 193 Families. Generally, Each Order Has Been Discussed In The Light Of Phylogeny And With Emphasis On Its General Features, Circum Inter-Relationship, Origin And Means Of Identification Of Various Families (By Bracketed Keys). Those Families Prominent In The Countrys Flora Have Been Described Under Six Or Seven Different Heads, Depending On The Available Information. Though The Inconspicuous Ones Have Not Been Categorised Likewise, One Can Even Find In Them The Array Of Items Under Each Family Being Suitably Treated. Moreover, The Nomenclature Of Plants Have Been Checked And Brought Up-To-Date As Far As Possible. Part One Is An Expose Of Taxonomic Principles, While PartsThree And Four, Deal With The Dicotyledonous And Monocotyledonous Plants Respectively. Under Part Two, There Are Certain Specialised Topics Which Have A Bearing On The Study Of The Systematic Botany Of Angiosperms. A List Of Important Books And Papers Is Inserted At The End Of Each Part. In Brief, The Author Has Made Anattempt To Give A Complete Picture Of Angiosperm Systematics.

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.

The Biology and Utilization of Grasses reviews current knowledge about grass biology, and it highlights the important role of grasses in human existence. It discusses many fundamental aspects of grass biology, including evolution and genetics, morphology, physiology, and ecology, with emphasis on the relationship of these basic concepts to the use of grasses for forage, turf, and rangelands. Comprised of 28 chapters, this volume begins with an overview of the evolution and genetics of the grass family, followed by a discussion on practical grass-breeding problems. The reader is also introduced to vegetative growth and development of seedlings and mature plants; the ecological aspects of grasses; soils and mineral nutrition in relation to grass growth; the effects of defoliation (moving or grazing); carbohydrate reserves; physiology of flowering; and grass seed production and culture treatments. Other chapters consider the role of polyploidy in the evolution and distribution of grasses; selection and breeding of grasses for forage and other uses; seedling vigor and seedling establishment; environmental modification for seedling establishment; the microclimate of grass communities; effects on turf grass of cultural practices in relation to microclimate; and competition within the grass community. This book will be of benefit to plant breeders, ecologists, botanists, and biologists.

Vistas in Botany features the study of life histories of plants, their development from spore or seed through vegetative phases up to the diverse phenomena of reproduction needs. This book is a compilation of studies and research conducted by several botanists that discuss topics such as the taxonomy general principles and Angiosperms; plant biochemistry; causal plant ecology; plant geography; cytology; genes, chromosomes, and evolution; viruses; bacteria; fungi; Bryophyta; Pteridophyta; Gymnospermae; and plant physiology. This publication is valuable to botanical specialists who wish to obtain updated knowledge in botany or phytology, and to students conducting research on the science of plant life.
