摘　　要：描述了中国广西凤仙花科Balsaminaceae凤仙花属Impatiens一新变种——瑶山凤仙花I. macrovexilla var. yaoshanensis S. X. Yu, Y. L. Chen & H. N. Qin。该变种与原变种不同在于叶卵圆形或卵状矩圆形, 侧生萼片全缘, 翼瓣的上部裂片全缘, 翼瓣背部的小耳明显, 此外花粉形态和种皮纹饰等性状也支持该变种的建立。Impatiens macrovexilla Y. L. Chen var. yaoshanensis S. X. Yu, Y. L. Chen ＆ H. N. Qin, a new variety of Balsaminaceae from Guangxi, China, is described. Variety yaoshanensis differs from the typical variety by having ovate-orbicular or ovate-oblong leaves, entire lateral sepals, an obvious auricle and entire distal lobe of the alae and visibly ridged seeds. Micromorphological characters of the pollen grains and seed surface under SEM of the two varieties also support the recognition of this taxon.
