But the marvel Tribe IX—Cupanieae. 48 genera and 404 species, by far the largest tribe in the family. However, to date only about 10 species seem to have attracted some garden interest. These are tropical evergreen trees and shrubs, a few valued for their wood. Further field work and study should reveal con siderably more native usage and folklore. The chief world centers of origin of the tribe are 3 in number: (a) The Pacific Islands, south eastward to Australia, and westward and northward to the Asiatic mainland. Within this area there have been described 28 genera and 247 species. There are 10 endemic, monotypic genera: 2 in the Philippines. 1 in Siam, 2 in Indo China, 1 in Hainan, China, 2 in Australia and 1 in New Guinea, a main center of origin of the tribe. Considerably off line, in Zanzibar, East Africa, is also 1. (b) The African-Madagascar subdivision, with 9 genera and 60 species. These are mod erately sized genera, each with 5 to 12 species, except for Bemarivea of Madagascar which is en demic and monotypic. Within this group is Blighia sapida Koen. the <Akee,* a semi-popular trop ical fruit which apparently reached the American tropics from Africa where it is highly developed and widely grown. Later in cultivation it was carried into the Pacific and Asiatic areas. It seems to be the only important economic species of the tribe, (c) The.Tropical American Subdivision, an independent group of 11 genera and 97 species. Cupania, 42 species, and Marayaba, 43, are quite widespread in distribution, the former attracting far more attention by plantsmen than has the latter. All other genera have onjy 1 or 2 species. In Brazil, especially in the northern portions, are found 5 genera; also in Guiana, Argentine, Costa Rica and Peru, 1 each. The independence of each of the above centers in Cupanieae origins, natural relationships and dis tribution is impressive. Only Allosanthus of Peru seems possibly derived from Eriocaelum, a trop ical African genus of 9 species, one of which is also of South American origin, in Spanish Guiana.
