Download or read book Microscopic Venation Patterns of Leaves and Their Importance in the Distinction of tropical Species written by Ingrid Roth and published by . This book was released on 1996 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the present publication, the structural studies of the ROLLET-Collection in Venezuelan Guiana are completed. Hundreds of tree species were studied concerning their bark structure, their leaf anatomy and fruit structure. The picture is now rounded off by the investigation of the leaf venation described in detail in this book, accompanied by many instructive figures. The book will be of interest not only to anatomists, taxonomists and ecologists but also to the teachers explaining the extraordinary tropical flora.

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.

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 Monograph of Mitrephora Annonaceae written by Aruna D. Weerasooriya and published by . This book was released on 2010 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The genus Mitrephora (Annonaceae) comprises 47 species of small to medium-sized trees, growing in tropical lowland and submontane forests throughout Southeast Asia. The centers of diversity lie in Borneo, where there are 12 species, and the Philippines, where there are 11 species. The flowers are pendent and hermaphroditic, with two whorls of petals, of which the outer petals are larger. The inner petals are apically con-nivent over the productive structures, forming a partially enclosed pollination chamber with small apertures between the basal claws of the petals that enable entry by pollinators. A field study of the pollination ecology of M. heyneana in Sri Lanka (the first such study for the genus) revealed pollination by small nitidulid beetles, although it is possible that other species may be fly-pollinated. This monograph is the first comprehensive taxonomic revi-sion of the genus. The work is based on a comprehensive study of comparative morphology and anatomy, including a survey of previously published work. Conservation assessments are provided for each species, according to current IUCN Red List categories and criteria. All species are mapped and many are illustrated with line drawings and/or photographs. Separate keys for flowering and fruiting material are included, as well as regional keys. Seven new species (M. amdjahii, M. endertii, M. kostermansii, M. multifolia, M. sorsogonensis, M. sundaica, and M. uniflora) and one new combination (M. macrocarpa) are proposed"--Publisher's description.

Download or read book Plant Identification written by William Hawthorne and published by Routledge. This book was released on 2013-06-17 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important prerequisite for successful conservation is a good understanding of what we seek to conserve. Nowhere is this more the case than in the fight to protect plant biodiversity, which is threatened by human activity in many regions worldwide. This book is written in the belief that tools that enable more people to understand biodiversity can not only aid protection efforts but also contribute to rural livelihoods. Among the most important of those tools is the field guide. Plant Identification provides potential authors of field guides with practical advice about all aspects of producing user-friendly guides which help to identify plants for the purposes of conservation, sustainable use, participatory monitoring or greater appreciation of biodiversity. The book draws on both scientific and participatory processes, supported by the experience of contributors from across the tropics. It presents a core process for producing a field guide, setting out key steps, options and techniques available to the authors of a guide and, through illustration, helps authors choose methods and media appropriate to their context.
