Impatiens nushanensis (Balsaminaceae), a new species from Yunnan, China

Abstract

Impatiens nushanensis (Balsaminaceae), a new species from Yunnan, China, is described and illustrated here. The new species is morphologically most similar to I. purpurea, but differs by having two pairs of lateral sepals and deep purple lower lobe of the lateral united petal with an acuminate and ribbon-like apex. Furthermore, phylogenetic analysis based on molecular data also support the recognization of this new species.

Impatiens zhaojueensis (Balsaminaceae) sp. nov. from Sichuan, China

“…Due to its unique landform and variable climate, southwestern China (covering the provinces of Sichuan, Yunnan, Guizhou, Tibet and Chongqing) is home to a variety of Impatiens species. In recent years, numerous new species have successively been discovered in this area (Cai et al 2015, Luo et al 2015a, b, Tan et al 2015, Ding et al 2016, Guo et al 2016, Xia et al 2019, Peng et al 2020, 2021a, b, Xue et al 2020, Zhang et al 2020, Gu et al 2021, Liao et al 2021, Song et al 2021a, b, Ren et al 2022, Wang et al 2022, Yuan et al 2022a), increasing China's Impatiens species to 352 (Yuan et al 2022b).…”
