Download or read book Flowering Plants written by Armen Takhtajan and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Download or read book Flowering Plants Eudicots written by Joachim W. Kadereit and published by Springer. This book was released on 2016-04-09 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume covers the orders Boraginales, Garryales and Solanales (except Convolvulaceae) of the Lamiids (Asterids I) as well as three unplaced families of that clade, i.e. Vahliaceae, Icacinaceae and Metteniusaceae, and the orders Aquifoliales, Escalloniales, Bruniales, Dipsacales and Paracryphiales of the Campanulids (Asterids II). It is the first of two final volumes to (almost) complete the treatment of the Asterids, which started with Vol. VI (Cornales, Ericales, 2004) and continued with Vol. VII (Lamiales, 2004) and Vol. VIII (Asterales, 2007). The present volume provides descriptions for 35 families and altogether 340 genera, including three genera of somewhat uncertain family affiliation. It provides identification keys for families within orders and for all genera within families, and also discusses probable phylogenetic relationships. The wealth of information contained in this volume makes it an indispensable source for all those working in pure and applied plant sciences.

Download or read book Seeds written by Carol C. Baskin and published by Elsevier. This book was released on 2014-02-20 with total page 1601 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. - Most wide-ranging and thorough account of whole-seed dormancy available - Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent - Includes a taxonomic index so researchers can quickly find information on their study organism(s) and - Provides a dichotomous key for the kinds of seed dormancy - Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy - Much attention is given to the evolution of kinds of seed dormancy - Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks - Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy - Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth
Download or read book Vistas in Botany written by W. B. Turrill and published by Elsevier. This book was released on 2013-10-22 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
