My intention in preparing the present work has been to bring together, for the guidance of those who live in the tropical and subtropical regions of the globe, the available information concerning the principal fruits cultivated, or which may be cultivated, in those regions. The banana, the coconut, the pineapple, the citrus fruits, the olive, and the fig are not included, however, since these have been fully treated by other writers. Nor have I attempted to describe all of the fruitbearing plants of the tropics: rather has it been my aim to concentrate on those which most seem to merit extensive cultivation, the culture of many of which is as yet little understood. No work in the English language has attempted to cover this subject, and the few which have appeared in other languages do not contain the data concerning propagation and cultural practices which would make them useful to horticulturists. Unfortunately, as regards many of the less-known fruits, few data are available, but concerning the more important ones the researches of such workers as E. Bonavia, AC Hartless, and William Burns in India, HA Van Hermann, FS Earle, and CF Kinman in the West Indies, George B. Cellon, Edward Simmonds, WJ Krome, PH Rolfs, and Reasoner Brothers in southern Florida, F. Franceschi (EO Fenzi) and Ira J. Condit in California, JE Higgins and his associates in Hawaii, PJ Wester in the Philippines, and L. Trabut in the Mediterranean region, have brought to light much valuable information.
