Description: A reproduction of a card index, prepared 1894-1903 by Josephine A. Clark at the U.S. Department of Agriculture Library and (since 1903) by the Gray Herbarium. The set reproduces about 265,000 cards published between 1894 and 1966. It is an indispensable tool for the taxonomy of NorthAmerican plants, covering all vascular plant taxa of the Western Hemisphere beginning with literature of 1886. For earlier names use the original volumes of Index kewensis. "Each card bears the scientific name of the plant, an abbreviation of the publishing author, a bibliographical reference to the place of publication and a brief statement of the geographic location of the taxon. New names and new combinations of names are indexed and the synonym involved is provided on each card" (Preface). Cross-references are provided, and when corrections are needed they are supplied on new cards.
Notes: A reproduction of a card index, issued 1894-1903 in 20 installments by Josephine A. Clark. Since 1903 the index has been published by the Gray Herbarium, currently 3 installments per yr. of 1000 cards per issue. Cf. Pref., signed: Reed C. Rollins, director.
