contains approximately 3,757 primary and 3,084 subsidiary titles, a total of 6,841, and treats an area of about 3,044,174 square kilometers (1,175,357 square miles). Thus, it has one primary title for each 810 square kilometers (313 square miles), while the first part had one for every 31,672 square kilometers (12,228 square miles), or a ratio of 39 to 1 in favor of the present part; if the subsidiary titles are included in both cases, the ratio rises to 61 to 1.
The purpose of this publication is essentially, as in the previously published part, to furnish an annotated, geographically and alphabetically arranged catalog of all the now useful floras and floristic works, including those in periodical or serial literature, that list or describe the complete vascular flora (or the phanerogams or pteridophytes only) of any region or locality. The work also includes all essentially complete publications on useful, weedy, poisonous, or woody plants, vernacular names, and botanical bibliography; and for each country (but mostly not for parts of a country) one or more works on ecology and phytogeography, when these are available. For the most part only the later works relating to a given area or subject are treated in full, although earlier publications of the same scope are nearly always mentioned under the titles of works that have replaced them. In general, all available local floras (such as the floras of towns or equivalent districts), regardless of age, are entered even though there may be later works (such as county floras) of wider scope that cover their territory. A considerable proportion not only of the very local floras but also of those of counties, provinces, and similar regions are old and by modern standards inadequate, but they are included because they will be of use to the local student and because they are needed to give a complete picture of our present knowledge. Publications dealing with only a part of the phanerogamic flora, such as a single family or larger division, or a single group of useful plants, such as those producing dyes or resins, are excluded, except for complete papers on edible or medicinal plants. No attempt has been made to evaluate the titles listed, but the presence of an item may be regarded as an indication that it has some current utility. Publications that are primarily ecological or phytogeographical have been excluded unless they contain fairly complete lists of the plants of the area discussed. Works of the "popular" type, intended for beginners in botany, have been omitted except for a few that provide a sufficient number of illustrations to be of value to the scientific worker.
Except for unintentional omissions, this work contains all the available nominally complete publications on the vascular flora and the useful (including cultivated) and injurious plants, vernacular names, and botanical bibliography of the countries treated, as well as a considerable number of incomplete publications on the same subjects, which for one reason or another have seemed worthy of inclusion. It differs in scope from the first part principally by including all complete works on pteridophytes, weeds, and poisonous and cultivated plants; by giving a few
general works on ecology, phytogeography, and related subjects; and by indicating the libraries in which all works not available in Washington were examined or the name of the correspondent who supplied information about them. Parenthetically, it may be stated that only about 64 of the works given in part I were not then available in Washington, and that some of them have since been added to libraries here.
Like part I, this list is fundamentally based on the subject card catalog of botany in the library of the United States Department of Agriculture, begun in 1906 under the direction of the late Dr. Frederick V. Coville by Majorie F. Warner and Alice C. Atwood, and continued by them and their assistants and successors until July 1952. However, the smaller and the more local publications on European botany are so much less completely represented in the catalog, and so many of them are not available in this country, that much more extensive research has been necessary both in literature and in American and foreign libraries to attain the essential completeness of the first part. As before, not only the Washington libraries (Department of Agriculture, Library of Congress, Smithsonian Institution, National Library of Medicine (formerly Surgeon-General's Library), and Geological Survey), but those of the Gray Herbarium and the Arnold Arboretum (now in process of combination into one) and the New York Botanical Garden have been examined. In addition, in the summer of 1950, the author examined the libraries at the Muséum National d'Histoire Naturelle in Paris; the Botaniska Avdelningen of the Naturhistoriska Riksmuseum in Stockholm; the Universitetets Botaniske Museum, Copenhagen; the Botanisch Museum en Herbarium, Utrecht; the Rijksherbarium and the collection of the Koninklijke Nederlandse Botanische Vereniging, Leiden; the British Museum (Natural History), South Kensington; the Royal Botanic Gardens, Kew; and the private libraries of N. Douglas Simpson and George Taylor, in England. The authorities of the Lloyd Library, Cincinnati, have lent many volumes and afforded help in other ways, and Rogers McVaugh of the University of Michigan has looked up many French publications in the University library.
In nearly every country the author has benefited by the assistance of one or more botanists, without whose help the work would be much less complete. The following merit particular mention in this connection: In Belgium, Walter Robyns; in Denmark, J. B. Hansen; in Finland, Hans Luther; in France, Georges Dillemann of Paris, Bernard de Retz of Versailles, and Paul Jovet of the Muséum National; in Great Britain, D. H. Kent of London, H. S. Marshall, E. J. Salisbury and George Taylor of Kew, and N. Douglas Simpson of Bournemouth; in Iceland, Áskell Löve, now of Montreal, Canada; in Italy, Luigi Fenaroli, Valerio Giacomini, Rodolfo Pichi-Sermolli, and the late Francesco Sappa; in Luxembourg, F. L. Lefort, now of Montreal, Canada; in Ñether
Current publications are listed in the monthly Bibliography of Agriculture, published by the Department of Agriculture library and now (1959) in its 23d volume, but no additions are made to the botany card catalog. The botany subject catalog is now published in book form.
