Revisio Aceracearum Japonicarum

In the year 1902, Dr. F. PAX published, in Engler's "Das Pflanzenreich," his excellent monograph of the Aceraceae, in which the genus Acer was divided into 13 sections, comprising 114 species in all, besides a large number of varieties and forms. Since that publication, new species have been added to the genus from Eastern Asia, especially from the Sinico-Japanese region augmenting the total number of known species up to 127. In 1905, a new section of the genus was proposed by Dr. REHDER, based on certain species found in eastern continental Asia, in addition to those of PAX. The present monograph deals with Acer found in Japan proper, Loochoo Islands, Formosa and Sachalin. Based on the results of careful examinations and revisions of each species, I have attempted to present a new systematic arrangement of the genus on the principle of bringing out as far as possible the phylogenetic relations of the members. The vernacular names of every species are taken principally from the works of Prof. J. MATSUMURA and Prof. M. SHIRAI. The present work was taken up at the suggestion of Prof. J. MATSUMURA, to whom I beg herewith to express my grateful thanks for the many acts of kindness renderd me during my studies. I am also under great obligation to Prof. M. SHIRAI who helped me in many matters regarding the literature. Further to Dr. Y. SHIRASAWA, Prof. G. YAMADA, and Mr. T. KAWAKAMI of the Formosan government, I am much indebted for the valuable material placed at my disposal
