Book Description
This second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

Book Description
Although the only publication with a realistic claim to the title "The plant diver sity of Malesia" is Flora Malesiana itself, we have hesitatingly chosen this title for the present proceedings volume. Past, present and future work on the Flora Malesiana project was the subject of a successful symposium held in August 1989. This book contains only a selection of the papers presented at that meet ing, yet it covers a much greater diversity of themes than just the inventory of botanical diversity. It even goes beyond the boundaries of the vast Flora Malesi ana region in several of its chapters. The role of the founder of the Flora Malesiana Project, Professor C.G.G.J. van Steenis, repeatedly recurs in several chapters; not only as director of and contributor to the project, but also as a pioneer in the fields of Malesian vege tation, conservation and biogeography, and as an enlightened systematist whose ideas and practical recommendations for taxonomic delimitation still largely apply. Botanical information made available in regional and local floras is of vital im portance for applications such as the exploitation of natural forests on a sus tainable yield basis. for establishing gene banks for the benefit of agriculture. forestry and horticulture. and not in the least for nature conservation. Several chapters are devoted to these themes. Floristic studies are also at the basis of the biogeographical essays and vegetation studies included in this book.

Book Description
The Marquesas Islands (French Polynesia) are an isolated group of volcanic hot spot islands in the SE Pacific Ocean. Intensive botanical exploration of the Marquesas for the Vascular Flora of the Marquesas Islands and Flore de la Polyn?sie fran?aise projects has resulted in numerous new collections. The nine precursor papers in this issue include three new combinations and descriptions of 18 new species and one new variety of ferns and flowering plants, bringing the total number of new species described in conjunction with these projects to 62. Most of these new species are extremely rare and localized, and they have been assigned preliminary IUCN Red List ratings of Endangered or Critically Endangered. This clearly demonstrates that field work and biological inventories are essential to enhance our knowledge of insular biodiversity and provide critical information for conservation of organisms and habitats. The Vascular Flora of the Marquesas Islands is a collaborative project between the National Tropical Botanical Garden, Smithsonian Institution, and D?l?gation ? la Recherche (French Polynesia) under the direction of David H. Lorence and Warren L. Wagner.

Book Description
The Ecology of Nusa Tenggara and Maluku is a comprehensive ecological survey of a series ecologically diverse islands in the Pacific. It contains extensive baseline data on the region’s people, ecosystems, biodiversity and land use, and discusses these in a historical as well as a developmental context. It also provides guidelines for scientific researchers on worthwhile ecological and socio-economic research projects. This region is the most diverse in Indonesia. Its myriad islands range from small atolls to active volcanic islands rising 3,500 meters above sea level. Each province has extensive coastlines—only 10 percent of the province of Maluku is land. The seas include shallow continental shelves and some of the deepest sea basins in the world. The complexity and vulnerability of these islands mean that development and environment are inextricably linked. If this is not understood and acted upon, there is no possibility for the ecologically sustainable development of Nusa Tenggara and Maluku.

Book Description
This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.
