Botanical trip to Iriomote-jima, Ishigaki-jima and Okinawa-jima, the Ryukyu islands, has been carried out during the days from 10th to 18th on October in 1986, since there are a few specimens in the Herbarium at Kyoto University. 760 sheets of specimens newly collected from the islands have been sorted together to the Herbarium. Based on both our and previous materials in the Herbarium, taxonomic and phytogeographic studies have been carried out.Koyama published two papers. "Taxonomic studies in the Compositae of Thailand 7" includs the subtropical elements of the Ryukyu islands and the other is "Taxonomic notes on Lindera umbellata and its allied in Japan", of which the family is very common in tropical and subtropical regions of Southeast Asia.Having studied on the genus Cinnamomum, Murata has reached the conclusion that "Nikkei" is not "C. sieboldii Meissn. "' but "C. okinawaense Hatus." inthe course of his taxonomic investigation on the flora of the Ryukyu islands.The flora of Japa … More n, northwards Yaku-shima, which has close affinity to those of middle china and Himalayas, has been considered to be a part of Sino-Japanese middle China and Himalayas, has been considered to be a part of Sino-Japanese floristic region, while that of the Ryukyu has been recognised to be a part of Southeast Asiatic floristic region. As being increasing the floristic knowledges of Southeast Asiatic region, however, very few species have been found as a species endemic to that region.Making the check list of widely distributed species in the Ryukyu islands, we have found that there are 400 species, one-fifths of the Ryukyu flora, which are spreading northwards so far as the Ryukyu from Southeast Asia under subtropical temperature. On the other hand, in the species endemic to Southeast Asia. In addition, some species endemic to the Ryukyu there are no species closely related to the Ryukyu are recognised to have close affinity to the species confined to the middle China and/or Japan. Thus, the flora of the Ryukyu islands can be considered to be a part of Sino-Japanese floristic region. Less

由于京都大学标本馆有少量标本，1986年10月10日至18日期间，对琉球群岛的伊里奥莫特岛、石垣岛和冲绳岛进行了植物学考察。从这些岛屿上新收集的760张标本已经被一起分拣到标本馆。根据植物标本馆的资料，进行了分类学和植物地理学研究。《泰国菊科植物分类研究7》收录了琉球诸岛的亚热带成分，另一篇是《关于伞形乌鸦及其日本近缘的分类注释》，该科在东南亚热带和亚热带地区非常常见。村田对肉桂属进行了研究，得出结论：“Nikkei”不是“C.sieboldii Meissn”。而是“冲绳华南星”。在他对琉球岛植物区系的分类研究过程中.日本…的植物区系北上与中国和喜马拉雅中部关系密切的雅库什岛被认为是中日中部中国和喜马拉雅的一部分，被认为是中日植物区系的一部分，琉球被认为是东南亚植物区系的一部分。然而，随着东南亚地区植物区系知识的增加，作为该地区特有种的种类很少。通过对琉球群岛广泛分布的物种名录进行核对，我们发现有400种，占琉球植物区系的五分之一，在亚热带温度下从东南亚向北蔓延到琉球群岛。另一方面，在东南亚特有的物种中。此外，一些琉球特有的物种没有与琉球有密切关系的物种被认为与局限于中国中部和/或日本的物种有密切的亲缘关系。因此，琉球群岛的植物区系可以认为是中日植物区系的一部分。较少
