Based on work spanning a decade, this study of the Maquipucuna area on the western slopes of the Andes discusses the climate, vegetation, ecological relationships, and flora, and emphasizes the importance of the Maquipucuna area as a biological reserve. In addition to the checklist of the flora, which enumerates 1,650 species (including 228 species of pteridophytes and over 200 species of orchids), appendices give information on floristic composition of communities, distribution of epiphytes, and elevational ranges of families and genera. The illustrations include a map, landscapes, and characteristic species.

The 50th volume of Progress in Botany appears in new guise. In cooperation with Springer-Verlag we have changed from the less attractive typewriter composition to the direct reproduction of a manuscript which was writ ten by means of a text editing system and produced by a laser printer. We, the editors, should like to take the appearance of Volume 50 as the occasion for a few short remarks. Our younger readers are perhaps not aware that our Book Series was founded in 1931 by Fritz von Wettstein, based on the following thoughts and considerations, aptly formulated by him in the Preface to the first volume. "One of the greatest dangers threatening progress in the science of botany is the absolutely unbelievable growth in volume of the literature. The quality of journals, books and individual works that are daily sent to us makes it impossible for anyone person to maintain a general view of the progress made in botany in all the specialized fields, let alone to find time for results from associated su bjects. For varying reasons, every botanist must find this state of matters insupportable. Let us endeavor, in the general interest, to retain a wide background of knowledge, and not become limited specialists. The vitally necessary connections between the specialized fields can only flourish, or even exist, if the general view of botany as a whole can be maintained.

Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.
