For a batter understanding of the diversity and differentiation of the flora in the limestone areas of the Sino-Japanese floristic region, field expeditions were made in the southwestern China and also Taiwan and Myanma. Through the expeditions more than 3000 herbarium specimens were prepared. The samples for molecular phylogenetic studies and the study of chromosome numbers were also obtained. Specimens were brought back to Japan and examined together with those gathered through previous activities. Dulicate specimens were studied in the Kunming Institute of Botany, China, by the Chinese counterpart. As the results, specimens obtained from the limestone areas during 1995 and 96 were identified and complied into a list. Two new species of Arisaema from China and one new species of Typhonioum from Myanmar were found. Many other new species were recoginizxed and will be described soon. Population analysis based on the allozyme polymorphism and molecular phylogenetic analysis were made on (Hepaticae), Magnoliaceae, Pedicularis, Araceae, Thymelaeaceae, Lobelia, Aucuba, Aristolochia and Stachyurus. Although the limestone areas extend widely and rather continuously, it is evident that the plants are locally differentiated.

为了更好地了解中日植物区系石灰岩地区的植物群的多样性和分化，我们在中国西南部以及台湾和缅甸进行了实地考察。通过考察，制作了3000多份植物标本。同时获得了用于分子系统学研究和染色体数目研究的样品。标本被带回日本，与通过以前的活动收集的标本一起进行检查。在昆明植物研究所，中国同行进行了研究。作为结果，1995年和1996年从石灰岩地区获得的标本进行了鉴定，并编入一份清单。发现中国天南星属二新种，缅甸香蒲属一新种，另有多个新种被发现，并将在以后的描述中予以描述。对苔类、木兰科、马先蒿属、天南星科、百里香科、半边莲属、桃叶珊瑚属、马兜铃属和旌节花属植物进行了等位酶多态性居群分析和分子系统发育分析。虽然石灰岩地区广泛而连续地延伸，但很明显，植物是局部分化的。
