Several years ago the Director of the Bernice P. Bishop Museum, Honolulu, was kind enough to lend me the Sapotaceous material from the Pacific region preserved in its Herbarium. It has been enumerated underneath together with additional material from other herbaria. These have been quoted by means of the following abbreviations, which are taken from Lanjouw’s list, published in Chronica Botanica V, 1932, 142. A. = Arnold Arboretum of Harvard University, Jamaica Plain (Mass.), U.S.A. B. = Botanisches Museum, Berlin-Dahlem. Bish. = Bernice P. Bish. Museum, Honolulu, Hawaiian Isl. and some specimens from the private herbarium of Mr O. Degener. Bz. = Herbarium, Gov. Botanic Gardens, Buitenzorg, Java. Cal. = California Botanical Gardens, San Francisco. G. = Institut de Botanique systématique de l’Université de Genève. GB. = Botanical Garden, Göteborg. GH. = Gray Herbarium of Harvard University, Cambridge (Mass.), U.S.A. K. = Royal Botanic Gardens, Kew. L. = Rijksherbarium, Leiden. NY. = New York Botanical Garden, New York.

Besides, a number of the specimens quoted are probably represented in other, particularly American herbaria, of which no data were available. I wish to tender my sincere thanks to the directors of the institutions mentioned for their kind assistance.
