No. 2. World Geographical Scheme for Recording Plant Distributions, ed. 2

R. K. Brummitt with assistance from F. Pando, S. Hollis, N. A. Brummitt and others. 2001. xv, 137 pp.; 17 maps; 8 1/2 x 11"; 1 lb. Stiff paper cover. $10.00 plus shipping and handling. ISBN 0-913196-72-X.

This scheme meets the need for a standard yet adaptable system of geographical units for use in recording plant distributions and arranging specimens. Because a purely political arrangement cannot meet all the needs of botanists, the scheme's arrangement compromises between a politically and a phytogeographically oriented system. It identifies geographic units worldwide in a four-level hierarchy, incorporating continents, regions, provinces and countries. Each geographical unit at each level has its own numeric or alphanumeric code. The scheme is presented in five tables, the recognized geographical units are shown in 17 maps, and a gazetteer relates over 2,100 names to the overall system.


This series presents standards for formatting botanical data, prepared by the International Working Group on Taxonomic Databases for Plant Sciences (TDWG) to promote wider and more effective collaboration, dissemination and exchange of information among plant taxonomic databases.The second edition comes some nine years after the first, and, inevitably includes some changes. Although the need for stability has been a major consideration, political realignments have forced new concepts. Some of these have necessitated changes at national level, such as the segregation of Eritrea from Ethiopia and division of Czechoslovakia into Czech Republic and Slovakia. Others are due to the recognition of new administrative units within larger countries, such as Nunavut in Canada, Uttaranchal in India and Chongqing in China. A few changes also have been made in order to make better phytogeographical sense, such as the separation of all Himalayan states from the main body of India, and the uniting of New Guinea and the Solomons to form Papuasia. Others are merely a matter of nomenclature brought about by political name changes. All innovations in the second edition are tabulated to assist database managers in adapting to the new edition.
