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 Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Download or read book A Manual for the Identification of Plant Seeds and Fruits written by R.T.J. Cappers and published by Barkhuis. This book was released on 2022-02-05 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The taxonomic and ecological identification of individual seeds and fruits of wild and cultivated plants is not always straightforward. This book helps you to get started, and also serves as a basis for further identification. It describes the inflorescence(s) and infructescence(s) seen in each of a set of 30 plant families, as well as the morphology of the seeds and fruits (with special emphasis on typology), the dispersal units (diaspores), and, if present, heterodiaspory. The manual is richly illustrated with 640 color photos of inflorescences, infructescences, seeds, fruits, and diaspores. Technical terms are described in a glossary. Indices of scientific plant names and subject names are included. This book will be of interest not only to those engaged in the identification of seeds and fruits, such as those who work in seed testing, but also to taxonomists, ecologists, archaeobotanists, and florists who wonder what they are looking at. This handbook is a completely revised version of the first edition, which was published in 2013. An important adaptation relates to new developments in plant taxonomy and the classification of fruits and diaspores. The number of plant families has been extended from 19 to 30.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Systematics, Third Edition, has made substantial contributions to plant systematics courses at the upper-undergraduate and first year graduate level, with the first edition winning The New York Botanical Garden's Henry Allan Gleason Award for outstanding recent publication in plant taxonomy, plant ecology or plant geography. This third edition continues to provide the basis for teaching an introduction to the morphology, evolution and classification of land plants. A foundation of the approach, methods, research goals, evidence and terminology of plant systematics are presented, along with the most recent knowledge of evolutionary relationships of plants and practical information vital to the field. In this new edition, the author includes greatly expanded treatments on families of flowering plants, as well as tropical trees (all with full-color plates), and an updated explanation of maximum likelihood and Bayesian inference algorithms. Chapters on morphology and plant nomenclature have also been enhanced with new material.

Download or read book Flowering Plants written by K. Kubitzki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the International Association for Plant Taxonomy and was at tended by 80 participants from 14 countries. There have been several meetings in recent years which have dealt with the origin and evolution of the Flowering Plants so that it might be questioned whether yet another symposium dealing with more or less the same subject were really "justified. As the reader will see from the contents of the book, this symposium differed from similar ones held recently in two respects: 1. Emphasis was given to methodological aspects of the classification of higher taxa, and 2. much classificatory and evolutionary evidence relating to the higher taxa of Flowering Plants was presented.

Available in PDF, EPUB and Kindle. Book excerpt: The development of specialised feeding habits during the course of time by human beings is paralleled in the majority of animals, in particular have developed special peculiarities, and insect larvae which in most cases are quite characteristic of the species concerned. This applies especially to phytophagous insect larvae, and anyone with the requisite experience can say with a fair degree of certainty which insect larva is responsible for any damage to be found on a plant. It leaves behind a definite "feeding pattern" which might be compared to a "visiting card" on which the genus and species are marked in runic characters. Whoever has learned to read the runes can readily determine who has been feeding on the affected spot, solely on the basic of the "visiting card" left behind. From the known factors - the name of the plant and the type of feeding patter- and after some study of the various types of plant infestation, both the genus and species of the larva producing the feeding pattern can be worked out without difficulty. The importance of "feeding pattern investigation" has now far outstripped the successes to be obtained by normal collecting. Previously, when wishing to list the species of insects present in any given locality they were caught with the net, by sugaring and other methods. This always resulted in a very defective "list" of the insects in fact existing in the locality concerned.

Download or read book Cyclamen written by Christopher Grey-Wilson and published by Batsford Books. This book was released on 2015-02-05 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: A completely revised and updated edition of the most comprehensive study of the genus Cyclamen ever undertaken, this book covers species both in the wild and in cultivation, along with analyses of the many culrtivars. The book is beautifully illustrated with 200 colour photographs as well as line drawings and maps showing the distribution of the various species in the wild. A chapter is specially devoted to the very important florists' cyclamen, Cyclamen persicum, as well as detailed notes on cultivation and propagation. Cyclamen have become ever more popular as garden plants, and the number of nurseries specializing in them has increased. However, in its natural habitat, the Mediterranean region and western Asia, the 22 known species of Cyclamen are increasingly under threat from development of various sorts. As a result conservation is a major issue in the study of the genus. Cyclamen is an ideal genus for the specialist gardener, having sufficient species to make a collection worthwhile and enough variety to sustain interest throughout the year. There is great diversity in the form and colour of the flowers as well as in the shapes and patterns of the leaves. Some are hardy enough to grow unprotected in the garden, while others make excellent plants for sheltered areas and conservatories, with one or more species in flower at almost every time of the year. This book is the best available source of information for gardeners and horticulturists, and is also invaluable to botanists and taxonomists. Using a minimum of botanical jargon, it tells all those with an interest in the subject everything that they may need or want to know about this fascinating genus.
Download or read book Common Families of Flowering Plants written by Michael Hickey and published by Cambridge University Press. This book was released on 1997-01-28 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides a basic introduction to twenty five commonly occurring families of flowering plants, chosen for their economic, ornamental and ecological importance. It is designed to enable students of botany and related disciplines to gain some knowledge of the general characteristics of each family and also the relationships between them. An introductory section provides basic botanical information which is often assumed to be known and which is essential for a proper consideration of the families themselves. These are described in the second section of the book. For each family, information on its distribution, classification, general features and economic importance precedes a detailed description of a typical representative species. For the larger or more varied families several representative species are included. The text is illustrated throughout with clear and accurate line diagrams and accompanied by an exhaustive glossary.
