First multi-year cumulation covers six years: 1965-70.
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 3 contains accounts of 47 families, including those formerly included in the Leguminosae (Mimosaceae, Caesalpiniaceae, Fabaceae) as well as the large and important Rosaceae. Also included are those families formerly covered by the name Saxifragaceae (Saxifragaceae in the strict sense, Penthoraceae, Grossulariaceae, Parnassiaceae, Hydrangeaceae and Escalloniaceae).
This book provides essential information on the morphology, biology, phytochemistry, pharmaceutical prospects, evolution, phylogeny, biogeography, and taxonomy of Paris (Melanthiaceae), a morphologically distinctive plant genus with great economic importance. Since the establishment of this genus, 70 species and 24 subspecific taxa have been described, resulting in considerable confusion in species delimitation. In this book, the taxonomy of all described taxa is carefully revised. Based on multi-disciplinary evidences, a revised classification system of Paris containing five sections is outlined. Every species is provided with a concise but diagnostic description, a color illustration, photographs that highlight distinguishing characters, examined specimens and distribution range. The interspecific relationships are clarified with an identification key. This monograph offers taxonomists, evolutionary biologists, ecologists, horticulturalists, phytochemists, and practitioners a thorough and up-to-date overview about this interesting plant group. It is equally valuable for undergraduate and graduate students, teachers and professionals engaged in related fields.
Space experiments have opened practically all electromagnetic windows on the Universe. A discussion of the most important results obtained with multi-frequency photonic astrophysics experiments will provide new input to advance our knowledge of physics, very often in its more extreme conditions. A multitude of high quality data across the whole electromagnetic spectrum came at the scientific community's disposal a few years after the beginning of the Space Era. With these data we are attempting to explain the physics governing the Universe and its origin, which continues to be a matter of the greatest curiosity for humanity. In this book we describe the latest steps of the investigations bor...
Pulsars are stars, a significant part of whose observed energy output is not continuous but is emitted as distinct flashes or pulses of electromagnetic radiation. Many pulsars also emit some radiation weakly and constantly, forming a background for the more intensive pulses. Three distinct classes of pulsars are presently known to astronomers, according to the source of energy that powers the radiation: Rotation-powered pulsars, where the loss of rotational energy of the star powers the radiation X-ray pulsars, where the gravitational potential energy of accreted matter is the energy source, and Magnetars, where the decay of an extremely strong magnetic field powers the radiation. Although a...
This text is a reference work for botanists studying the flora of South Asia. As commander of Malabar, van Reed was responsible for compiling the Hortus Malabaricus, a major publication of the flora and medical use of plants.
This is the third volume in a series of six and contains accounts of the first 48 families of dicotyledons, including many well known trees. The series is a manual for the accurate identification of cultivated ornamental plants throughout the world, concentrating specifically on Europe.
The 'scientific revolution' of the sixteenth and seventeenth century continues to command attention in historical debate. Controversy still rages about the extent to which it was essentially a 'revolution of the mind', or how far it must also be explained by wider considerations. In this volume, leading scholars of early modern science argue the importance of specifically national contexts for understanding the transformation in natural philosophy between Copernicus and Newton. Distinct political, religious, cultural and linguistic formations shaped scientific interests and concerns differently in each European state and explain different levels of scientific intensity. Questions of institutional development and of the transmission of scientific ideas are also addressed. The emphasis upon national determinants makes this volume an interesting contribution to the study of the Scientific Revolution.
This volume provides the origins and meanings of the names of genera and species of extant vascular plants, with the genera arranged alphabetically from A to C.
