项目摘要

1)Glychine Koidzumii is a clearly distinct species from G.tabacina which is distributed widely from Australia, through Micronesia and Philippines to Taiwan and has been sometimes conspecific with the G.koidzumii. These two species are clearly distinguished by leaf, pod and flower morphology. Moreover, as a result of the comparative study of the Asiatic species of this genus, it is found that G.koidzumii is rather nearer to G.dolichocarpa, which is endemic to Taiwan. Comparing to G.tabacina and G.dolichocarpa, G.koidzumii is characteristic in having small pods withfewer seeds and ovate monomorphic leaflets.2) Glycine koidzumii is restricted in Miyako Island and Nothern Peninsula of Ishigaki Island, where it trailing on windy rocky cliff. G.koidzumii is seemed to have been survived in such a poor surroundingwith less nutrition and strong wind.3) Vigna minima var.minor, restricated to Taiwan, Yaeyama and Miyako Islands, is a form with small rounded leaflets and smaller pods with less seeds than var. minima.4) Okinawan plant of Vigna vexillata, which is distributed widely in tropics and subtropics, is characteristic in having small leaves, flower, pods and seeds.5) Rhynchosia minima f.nuda is supported as a geographical races of typical R.minima.6) A tendencies to smaller and rounded leaves and smaller pods with fewer seeds are found in some species of tribe phaseoleae.7) Pterocarpus of Ishigagki, which has long been considered as P.indicus distributed India and S.E.Asia, seems to be distinct species having characteristic spined pods.

1)甘氨酸（Glychine Koidzumii）是一种明显不同于G.tabacina的种，G.tabacina广泛分布于澳大利亚、密克罗尼西亚、菲律宾和台湾，有时与G.koidzumii同种。这两个物种在叶、荚和花的形态上有明显的区别。此外，对该属的亚洲种进行比较研究，发现该属与台湾特有的G.dolichocarpa更接近。与烟叶和扁叶相比，扁叶的特点是豆荚小，种子少，小叶卵形。2)甘氨酸koidzumii仅在宫古岛和石垣岛北半岛生长，在多风的岩石悬崖上生长。G.koidzumii似乎是在如此贫瘠的环境中生存下来的，营养不足，风很大。(3)最小变种，局限于台湾，八山岛和宫古岛，是一种小的圆形小叶和较小的荚果，种子比最小变种少。(4)日本冲绳地区的刺蒺藜（Vigna vexillata）植物广泛分布于热带和亚热带地区，其特点是叶子、花、豆荚和种子都很小。(5)小舌鼠（Rhynchosia minima f.nuda）是典型的小舌鼠的地理种族。6)部分菜籽科植物有叶片小而圆、豆荚小、种子少的趋势。7)石垣翼龙属（Pterocarpus of Ishigagki），长期以来被认为是分布在印度和东南亚的印度翼龙属（p.a indicus），似乎是一个独特的种，具有典型的带刺豆荚。
