I.Field works had been made in Taiwan from 5 Nov.to 22 Nov.1992, and in China and Hongkong from 29 Nov.to 23 Dec.1992.II.For cpDNA analysis of Euchresta, two Chinese taxonomists were invited to Japan from 5 Aug.to 1 Sep.1993. Field works had been made in China (Guangdon, Guangxi, Human, Hainan Isl.) and Hongkong from 19 Sep.to 9 Nov.1993.III.From 28 July to 14 Aug.1994, herbarium works had been made in China (Guangdong, Kunming and Beijing) and made a field work in China (Kunming).IV.From 24 Oct.to 6 Nov.1994 an International Legume Symposium had been held in Sendai, under the title, "Taxonomy and Distribution of the Leguminosae in SE.-E.Asia". Four taxonomists were invited from China and Taiwan. A proceedings of the symposium was published.V.Results of our researches in this project are summarized below :A.Taxonomic researches : 1. All the native species and infraspecific taxa of Desmodium and its allied genera of China are revised (Ohashi 1995a, b, c). 2. Chamaecrista. Differentiatio … More n of Chamaecrista mimosoides complex is clarified in China (Nemoto in preparation).B.Molecular Phylogenetic researches : 1. Desmodium.RFLPs of Chloroplast DNA were examined in five species of Desmodium subgenus Podocarpium (Kajita and Ohashi 1994). 2. Desmodium and its allies are examining on the basis of comparative analysis of rbcLgene. 3. Euchresta. Fresh materials of Euchresta japonica and E.tubulosa have been collected in Guangdong and Guangxi. CpDNA variations are analyzing for these species (Kajita et al.in preparation).C.Phytogeographic researches : 1.92 genera 424 species of the Leguminosae occur in South China of which about 20 % are with warm-temperate regions ; about 38 % are endemic to China (162 species) of which about 40 % (65 species) are endemic to South China (T.L.Wu et al.in preparation). 2.58 genera 165 species of the Leguminosae are known in Taiwan of which about 49 % of the species are commonly distributed with Japan and the Ryukyus ; 43 genera 73 species of the Leguminosae occur in the Ryukyus, and about 56 % of them are common with the Taiwan species ; 38 genera and 94 species of the Leguminosae are recorded from Japan-Hondo of which 51 % of are common with the Ryukyus and Taiwan. Based on the high percentage of common species and on the occurrence of some characteristic endemic species, Taiwan, the Ryukyus and Japan-Hondo are closely related in the distribution of the Leguminosae (Ohashi et al.in preparation).

1992Aug.to11月22日在台湾、12月23日在中国大陆和香港进行了实地调查Nov.toNov.to在中国（广东、广西、湖南、海南岛）进行了野外工作。Sep.to 1994年7月28日至8月14日，在中国（广东、昆明和北京）进行了植物标本室工作，并在中国（昆明）进行了野外调查。1994年11月6日至24日，在仙台举行了题为“东南豆科植物的分类与分布”的国际豆科植物研讨会。Oct.to东亚”。邀请了来自中国和台湾的四位分类学家。五、本课题的研究成果概括如下：A.分类学研究：1.分类学研究：修订了中国山蚂蝗属及其近缘属的所有种和种下分类群（Ohashi 1995 a，B，c）。2. Chamaecrista。微分 ...更多信息 在中国的Chamaecrista mimosoides复合体的研究中，明确了一个新的分类群（Nemoto在编制中）。在山蚂蝗属Podocarpium亚属的五个种中检测了叶绿体DNA的RFLP（Kajita和Ohashi 1994）。2. Desmodium及其盟友正在比较分析rbcL基因的基础上进行研究。3.尤克里斯塔在广东和广西采集了日本麒麟菜和管花麒麟菜的新鲜材料。al.in C.植物地理学研究：豆科植物92属424种分布于华南，其中约20%分布于暖温带地区;约38%为中国特有种（162种），其中约40%（65种）为华南特有种（T. L. Wu et al.in preparation）。2.58台湾已知豆科植物165属，其中约49%的种与日本和琉球共同分布，琉球有豆科植物43属73种，其中约56%的种与台湾共同分布;本岛豆科植物38属94种，其中51%为琉球和台湾特有种。基于常见种的高比例和一些特有种的出现，台湾、琉球和日本-本岛在豆科植物的分布中密切相关（Ohashi et al.in preparation）。少
