Studies of Pacific Island Plants , XX Notes on Some Fijian

IN RECENT YEARS collections made by staff members of the Fiji Department of Agriculture have substantially added to the available study material of Fijian plants, permitting more adequate knowledge of many species and the recognition of others as new to science. Study of the Rubiaceae of these collections has made desirable the publication of notes to clarify certain complexes within the genus Psychotria. During the course of this work the related genus Readea was also reviewed. In the present paper four species of Psychotria are described as new, and hitherto unpublished combinations are proposed for three others. The pertinent herbarium material of several institutions has been examined and some of it cited, with these indicated abbreviations: Arnold Arboretum of Harvard University (A); Bernice P. Bishop Museum (BISH); British Museum (BM); Gray Herbarium of Harvard University (GH); Royal Botanic Gardens, Kew (K); New York Botanical Garden (NY); Department of Agriculture, Suva, Fiji (SUVA); University of California, Berkeley (uc); and U. S. National Herbarium (us). The cooperation of administrators of these herbaria is appreciated.
