In her monograph, A. CAMUS recognized not less than 120 species. The distribution covers NE. India (Nepal, Bhutan, Assam), Burma, China (except in the N. and NW. parts),Korea, Japan, Formosa, Hainan, Indochina, Siam, Malesia, and SW. North America (1 sp.). The greatest assemblage and most primitive forms are found in SE. Asia (Indochina and Malesia). In Malesia 34 spp. (see ); the genus has been recorded from most islands except in the eastern half of Java and in the Lesser Sunda Islands; the largest number of species is found in Borneo. The only representative of the genus outside Asia, namely C. chrysophylla from SW. North America, has been recognized by HJELMQVIST (1948) and FOR-MAN (1966) as a separate genus, Chrysolepis, an opinion which I cannot share. .
