Biogeographical research on the present Himalayan flora

1.实地研究：在尼泊尔、缅甸和中国进行了实地研究。主要目的是收集植物标本和样品进行分子和细胞学研究，并观察繁殖和变异。(1)尼泊尔：贾勒贾勒（1999年8月至9月）和东尼泊尔（2001年5月至6月）。(2)缅甸：中部（2000年8月）。(3)中国：西藏东部（2000年7月至8月）和云南和西藏（2001年7月至8月）。材料与标本分析：（1）以采集标本为主进行分类学研究。(2)对虎耳草属、委陵菜属、凤仙花属、报春花属、风毛菊属和Cremanthdium属进行了细胞分类学研究。(3)对红景天属、虎耳草属、凤仙花属、风毛菊属和Cremanthdium属进行了系统遗传学研究.结果（1）本研究成果发表论文和讲座。(2)标本保存于东京大学植物标本室。来自中国的标本送中国科学院昆明植物研究所标本室，来自尼泊尔的标本送植物资源部。

1. Field research : Field research was held in Nepal, Myanmar and China. The main purposes are to collect herbarium specimens and samples for molecular and cytological studies, and observations on reproductions and variations.(1) Nepal : Jaljale Himal (August to September in 1999) and East Nepal (May to June in 2001).(2) Myanmar : Central part (August in 2000).(3) China : East Tibet (July to August in 2000) and Yunnan and Tibet (July to August in 2001).2. Analyzes based on collected materials and specimens(1) Taxonomical study was done mainly based on the collected specimens.(2) For cytotaxonomic study the following genera, Saxifraga, Potentilla, Impatiens, Primula, Saussurea and Cremanthdium were studied.(3) For phylogenetical study the following genera, Rhodiola, Saxifraga, Impatiens, Saussurea and Cremanthdium were studied.3. Results(1) The results of this research were published in papers and lectured.(2) The collected specimens were deposited in the Herbarium, University of Tokyo. The complete duplicate set was sent to Herbaria of Kunming Institute of Botany, Chinese Academy of Sciences for the plants collected from China, and Department of Plant Resources for those from Nepal.
