The Flora Europaea, originally published between 1964 and 1980, explores the synthesis of all the national and regional Floras of Europe. The second volume covers the Dicotyledonous families from Rosaceae to Umbelliferae. The text, in English, uses a limited vocabulary, and there are glossaries of technical terms and Latin equivalents.

The Flora Europaea presents for the first time a synthesis of all the national and regional Floras of Europe. It is based on a critical review of existing literature and on studies on herbaria and in the field. It aims to be simple as well as authoritative, and should enable the reader to name as far as its subspecies any fern, conifer or flowering plant growing wild of wildly cultivated. The second of the four volumes covers the Dicotyledonous families from Rosaceae to Umbelliferae, following the Engler system. Apart from keys and descriptions, information is given on geographical distribution and, where possible, on habitat preference and chromosome number. all names used in current Floras or important monographs are cited in the text or index. The text, in English, uses a limited vocabulary, and there are glossaries of technical terms and Latin equivalents.

This book simultaneously provides a useful checklist of all taxa published in Flora Europaea and documents the sources of all the chromosome numbers cited therein. It will be useful to anyone wishing to have ready access to the names and sequence of taxa used in Flora Europaea (for example in botanical libraries and herbaria) and for those involved with chromosome studies of the European flora.

This vol. is the first published product of the Pennsylvania Flora Database, created & maintained at the Morris Arboretum of the U. of Pennsylvania. The database has its roots in the work of Edgar T. Wherry, John M. Fogg, Jr., & Herbert A. Wahl, the Atlas of the Flora of PennsylvaniaÓ (Wherry et al. 1979), published by the Morris Arboretum. Over a period of 40 years, Wherry & his colleagues gathered data from the major Pennsylvania herbaria & manually placed a quarter of a million dots on over 3500 maps (Fogg 1944). The Pennsylvania Flora Database retains the emphasis on specimen-based, site-specific data. The checklist of included taxa has undergone extensive review to reflect recent taxonomic & nomenclatural revisions. Questionable specimens have been re-evaluated with the result that several taxa included in earlier works were dropped. Recent discoveries have been added & distribution data has been updated. This vol. also includes collections made in the 1990s in conjunction with the Pennsylvania Natural Diversity Inventory (PNDI), the state heritage program. The maps present the accumulated collection of information for each taxon as represented in the herbaria. Illus., reprinted 1996.

The book is the first comprehensive analysis of the macroecology and geobotany of endemic vascular plants with case-studies and analyses from different regions in the world. Endemism is a pre-extinction phenomenon. Endemics are threatened with extinction. Due to international nature conservation policies and due to the perception of the public the concept’s importance is increasing. Endemism can result from different biological and environmental processes. Depending on the process conservation measures should be adapted. Endemic vascular plant taxa, in the setting of their species composition and vegetation types are important features of landscapes and indicators of the quality of relating habitats. The book is an important basis for biologists, ecologists, geographers, planners and managers of nature reserves and national parks, and people generally interested in nature conservation and biogeography of vascular plants.
