GREENWOOD, FIJIAN WEEDS NOTES ON SOME FIJIAN WEEDS AND INTRODUCED PLANTS WILLIAM GREENWOOD A NUMBER of interesting weeds and introduced plants have been foundin Fiji in regions other than the leeward coasts and so were mentionedonly briefly in my previous articles on this general subject (Proc. Linn.Soc. 154: 92-106. 1943; Jour. Arnold Arb. 25: 397-405. 1944). In thepresent article notes on some of these plants are given. Some records ofweeds common to both the dry and wet zones in Fiji are also given, butno attempt has been made to list all the weeds noticed or collected duringvarious trips outside the dry zones. Some hitherto unpublished recordsfor Fiji are also included. In most such cases the records are based uponspecimens which are deposited in the herbarium of either the Royal BotanicGardens, Kew, the Arnold Arboretum, or the Gray Herbarium. In the articles mentioned above, published in 1943 and 1944, about 80records new to Fiji were published; A. C. Smith has also listed new recordsof weeds and introduced plants in Sargentia 1: 1-148. 1942, and in Bull.Torrey Bot. Club 70: 533-549. 1943. From these records one might con-clude that the number of weeds and introduced plants in Fiji is increasingrapidly, but I do not believe this to be the case. Many of the new recordsof recent years are from southeastern Viti Levu in the coastal portions ofSerua, Namosi, Rewa, Naitasiri. and Tailevu Provinces, especially near thetowns of Navua, Nasinu, and Nausori. Although the plants discussedmay have been established for years, these districts have not previouslybeen visited by anyone sufficiently interested in the weeds to collect andidentify them and to publish the records. In this paper families are discussed in the order of Bentham & Hooker'sGenera Plantarum. Collection numbers found in the text italicized andin parentheses refer to the writer's specimens; these numbers are insertedonly when the species has not previously been reported from Fiji. Someof the plants discussed were identified by members of the staff of the RoyalBotanic Gardens, Kew, to whom I am grateful. Dr. E. D. Merrill andDr. A. C. Smith, of the Arnold Arboretum, have identified most of thenew records and have assisted me in the preparation of this article. PORTULACACEAETalinum paniculatum (Jacq.) Gaertn. In Bull. Torrey Bot. Club 70: 537. 1943, Smith states that this specieshas been recorded, in Fiji, only from the island of Ovalau. During 30years' collecting in Fiji I have never seen it except in this one locality,near Levuka. Why this weed should have failed to spread, after its intro-duction into Fiji at least 80 years ago, and why it should have persistedaround Levuka are interesting questions.1949]
