HISTORICAL INTRODUCTION 
China and Japan. — A summary of the Chinese Roses is 
included in Forbes & Hemsley’s Index Florae Sinensis (1887), 
and descriptions of E. H. Wilson’s recent discoveries in the Kew 
Bulletin for 1907. The most recent summary of the Japanese Roses 
is contained in the two volumes of Franchet & Savatier’s Emimeratio 
(1875-6), and they give references to the figures in the illustrated 
Japanese botanical books. Thunberg in his Flora Japonica of 1784 
was the first to name two common garden species, Rosa multiflora 
and Rosa rugosa . Several new species from China and Korea have 
been published lately by Mgr. Leveille in Fedde’s Repertonum and 
the Bulletin of the Botanical Society of France. 
India. — The latest synopsis of the Indian Roses is in Sir J. D. 
Hooker’s Flora of British India (1872, etc.). Roxburgh, in his 
Hort. Beng . (1814), enumerates twelve species as cultivated in Bengal, 
and describes them in his Flora (1820-32). Copies of his drawings 
are at Kew. Wallich (1786-1854) distributed several in his her- 
barium, and Wight gives a good figure of the only South Indian 
species, Rosa Leschenaultiana ( 1 840). 
North America. — There are two monographs of the North 
American Roses — one by Cr6pin in vol. xv. of the Bulletin de la 
Societe Royale de Botanique de Belgique (1876), and one by Sereno 
Watson in vol. xx. of the Proceedings of the American Academy 
(1885). They are also treated by Torrey & Gray in the Flora of 
North America (1838-43), in the different editions of Asa Gray’s 
Manual of the Botany of the Northern United States (1848-78), in 
Brewer & Watson’s Botany of California (1876-80), in Coulter’s 
Flora of the Rocky Mountains (1885), and in two Floras of the 
Southern United States by Chapman (i860) and Small (1903). The 
Rev. E. L. Greene has described several additional species in Pittonia 
(1899-1901) and other periodicals, but few authenticated specimens 
of them have yet reached England.
