[Botany • 2007] Impatiens macrovexilla var. yaoshanensis • New Variety of Balsaminaceae from Guangxi, China




Abstract
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.

Key words: Impatiens, Impatiens macrovexilla var. yaoshanensis S. X. Yu, Y. L. Chen & H. N. Qin, new variety, Balsaminaceae, Guangxi, China.
