Pollen morphology and structure of the Japanese Leguminosae were examined by electron nicroscopy, and the results were described with comparison to those of related species in this study. Sophora franchetiana Dunn is a very rare species occurring discontinuously in southern Kyushu and Fukien in southeastern China.Taxonomic relation of this species to others became clear by examining pollen grains which have long colpi, large endoapatures and characteristic structures of tecta which are microperforate or perforate in mesocolpium and perforate, regulate or verrucate near colpus (Hoshi & Ohashi, 1989).All the native Japanese species of Vicia and Maackia were examined and described in pollen morphology and fine structure (Ohashi, 1990 a & b). The genus Lespedeza needed its clear boundary between Kummerowia and Campylotropis. Floral nectaries were found in Lespedeza and Kummerowia, but not in Campylotropis (Nemoto & Ohaslii, 1988). This fact suggest Lespedeza,is distinct and is closer to Kummerowia than Campylotropis.Based on this results, among the native Japanese Lespedeza (may be 16 species), pollen graitis of 13 species were described, and comparative studies of these taxs were made (Oliashi, 1990 c).

用电子显微镜观察了日本豆科植物花粉的形态和结构，并与本研究的近缘种进行了比较。Sophora franchetiana Dunn是中国东南部九州南部和福建不连续分布的一种非常罕见的物种。通过检查花粉粒，该物种与其他物种的分类关系变得清晰起来，花粉粒具有长茎尖、大内腔和微孔或中胚轴穿孔的特征结构，以及在茎尖附近穿孔、调节或疣状（Hoshi & Ohashi, 1989）。对所有日本本土种的薇琪亚（Vicia）和玛琪亚（Maackia）的花粉形态和精细结构进行了检测和描述（Ohashi, 1990 a & b）。胡枝子属（lepedeza）需要在kummerowiia和Campylotropis之间有明确的界限。在lepedeza和Kummerowia中发现了花蜜，但在Campylotropis中没有发现（Nemoto & Ohaslii, 1988）。这一事实表明，胡枝子是不同的，更接近于Kummerowia而不是Campylotropis。在此基础上，对日本本土胡枝子（可能有16种）中13种的花粉颗粒进行了描述，并进行了比较研究（Oliashi, 1990 c）。
