中国膨果豆属(豆科)一新组合

摘要

原簇毛黄耆亚属的部分种类从黄耆属中分出,在此基础上恢复了膨果豆属,由此也产生了许多新组合.其中,新组合蒺藜叶膨果豆包含了原蒺藜叶黄耆和甘青黄耆.为验证该分类处理的合理性,该文统计分析了蒺藜叶黄耆和甘青黄耆在果实形态上的差异,同时比较了二者的地理分布式样.结果表明:甘青黄耆和蒺藜叶黄耆之间存在着明显区别,甘青黄耆种级的分类学地位应予以保留,新组合为甘青膨果豆[Phyllolobium tangutica(Batalin)Y.Kang&M.L.Zhang].%Twenty combinations have been made for genus Phyllolobium when those species of subgenus Pogonophace were separated from Astragalus (Leguminosae). The former A. tribulifolius and A. tanguticus were included within the same com-bination Phyllolobium tribulifolium (Bunge) M. L. Zhang&Podlech. Based on the analyses of morphological characters and their distribution patterns, Astragalus tanguticus could be clearly distinguished from A. tribulifolius. Therefore, a new combi-nation was made for this former Astragalus species as Phyllolobium tangutica (Batalin)Y. Kang&M. L. Zhang.
