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. Key words Impatiens , Impatiens macrovexilla var. yaoshanensis S. X. Yu, Y. L. Chen & H. N. Qin, new variety, Balsaminaceae, Guangxi, China. In 2004, one of us (Yu) carried out field exploration in Guangxi and collected many species of Impatiens . After studying the collections morphologically and comparing their distributions, we noted that some plants resembling Impatiens macrovexilla Y. L. Chen did not match that species exactly. We then observed the micromorphology of the pollen grains and seed coat and determined that the collections represented a new variety, which we here describe.Read More
