O. Box 9514, 2300 RA Leiden, THE NETHERLANDS (Received on March 5, 2009) In 1851, Carl Lodewijk von Blume, who studied extensively the specimens collected in Japan by Siebold, Bürger, their successors, and their Japanese correspondents, described a great number of new species and varieties of Quercus and other genera of Fagaceae. His treatment, especially of Quercus, influenced later workers on the family, and also studies of the flora and vegetation of Japan. To stabilize the taxonomy of the family, lectotypes for taxa described by Blume are herein designated for Quercus (13 species and 13 varieties), Lithocarpus (1 and 2), Castanea (1 and 10), and Fagus (1 and 2). Key words: Fagaceae, Japanese flora, lectotypification, Siebold collections. Carl Lodewijk von Blume (Karl Ludwig not designate lectotypes. The type concept was von Blume) studied extensively the specimens not as well developed at those times as it is collected in Japan by Siebold, Bürger, their now. successors, and their Japanese correspondents. Siebold, Bürger, their successors, and Blume (1851) described a great number of their Japanese correspondents gathered the new species and varieties of Quercus and specimens from various sources. The majority other genera of Fagaceae, and his treatment, of the specimens appear to be from trees especially of Quercus, influenced later workers in spontaneous situations, but some were on the family and also studies of the flora and collected from cultivated trees in various vegetations of Japan. gardens and nurseries. Although several Japanese botanists During preparation of manuscripts on studied the specimens used by Blume, they Fagaceae for recent publications on the did not designate any lectotypes.
