摘　　要：笔者经过长时间对豆科的海红豆属Adenanthera、红豆属Ormosia、野扁豆属Dunbaria、山黑豆属Dumasia、胡枝子属Lespedeza…等12个属作了专属系统分类研究,陆续发现了一些新分类群。于是进行再调研与复查核实,补点采集和确认论证,在本文先报导1个新属、4个新种、3个亚种新组合和2个新变种,它们都是中国地理分布的地区特有分类群(除去1个亚种)其余将在另文续报。除此。作了其化学成分、药理试验、花粉与种皮的扫描电镜SEM观测及拍片分析和花、果、叶片和幼枝的比较形态解剖等研究,为新分类群的分类和区别及其亲缘关系提供佐证,为其新药筛选和其他应用开发、保护提供依据或参考。after long periol 12 genera systematic studing on Adenanthera. Ormosia. Dunbaria. Dumasia. Les-pedeza…etc in Leguminosae, the authors have found some rew taxa on the base of on-the-spot investigation , Now we report 1 new genus 4 new species 4 subspecies in new combination and 2 new variety, which were endemic taxa chinese geographic distributions (excluding of one subspecies). The others will report in continued papers. This research work dealt with (1)the systematization, iden-tification and revision of all available home-ab-voad specimens in more than 40 Herbaria; (2)the consultior of the taxonomic references about the specialized genera; (3)the expedition and investigation of them in open field,the collection,ascertainment and check of the novel taxa; (4)the dissection of flowers, fruits anc seeds; (5)the exemination of pollen grains and seed skin by scanning election microscopes; and (6)not only the identifi-cation of all available species and genera firmally but also the exploration of their phylogenetic relation and geographical distribution. Based on the taxonmic research of the specialized genus system, the novel taxa mentioned above were determined after many studies. Authors' purpose is to carry out the specialized systementic taxonomy and revision,to enrich and perfect their taxonomic system, and to develop, utilize, protect and expend these new medicinal or new fine species resourceo.
