摘要：
Impatiens damingensis S. X. Yu, C. Y. Xia & H. P. Deng, (Balsaminaceae) discovered in Guangxi, China, is described and illustrated here. This species is similar to I. aquatilis Hook. f., but differs from the latter by having blades that are ovate or ovate-lanceolate vs. lanceolate, ovate-lanceolate, or ovate-oblong; apices of bracts acute vs. glandular awned; apices of lateral sepals mucronulate vs. long mucronulate; and spur slender substraight or slightly incurved vs. incurved. Furthermore, molecular data as well as micro-morphological evidence under SEM (of pollens and seeds) also support the establishment of the new species.
