Abstract

This study describes Impatiensyingjingensis X.Q. Song, B.N. Song & Biao Yang, sp. nov., a new species collected from the Yingjing area of the Giant Panda National Park. This new species is distributed at an altitude of 1400-2100 m, with a plant height of 30-130 cm. The flowers are purple-red or light purple red, with 3-9 flowers on each inflorescence and the dorsal auricle of the lateral united petals is thread-like and about 2 cm long, differing significantly from other species of Impatiens. Furthermore, molecular data, as well as micro-morphological evidence under SEM (of pollens), also support the establishment of the new species.
