Over the past four centuries botanists and gardeners in the British Isles have gathered, maintained and propagated many varying species of plants. Their work has been documented in innumerable books and articles which are often difficult to trace. The Dictionary of British and Irish Botanists and Horticulturalists represents a time-saving reference source for those who wish to discover more about the lives and achievements of the horticulturalists listed. The dictionary's utility comes not only from indicating the major publications of the named authors, but also the location of their herbaria and manuscripts.; The previous 1977 edition of the Dictionary has for many years been a much used source of information for botanists, botanic artists and archivists. In this revised edition the scope has been expanded to include among its 13,000 entries flower painters in addition to botanical artists over 1400 entries and, for the first time, garden designers.; Finally the Dictionary should have international appeal since so many botanists and gardeners worked on collective plants overseas, in particular in North America and the British Commonwealth.; Each entry gives, wherever possible, details of dates and places of birth and death, educational qualifications, professional posts, honours and awards, publications, location of plant collections, manuscripts, drawings and portraits. Its main function, however, is to provide further biographical references to books and periodicals. Comprehensive classified indices facilitate access by professions and activities, countries, and plant interests.

Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.
