Description of a New Species and Lectotypification of Two Names in Impatiens Sect. Racemosae (Balsaminaceae) from China

“…Specimens were collected, preserved, and deposited in the Herbarium of Wuhan Botanical Garden, Chinese Academy of Sciences (HIB) for further identification. We then dissected the flower and carefully reviewed related literature [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]36,37] and herbaria specimens in a bid to ascertain the identity of the collected species. However, we were unable to match the new plants with any described species based on morphology.…”

“…The Flora of China lists 227 species, of which 187 are endemic [14]. According to Du et al [15], a total of 69 new taxa of Impatiens have been described in China between 2000 and 2019, and 13 new taxa [16][17][18][19][20][21][22][23][24][25][26][27][28] and three new records [28][29][30] have been published in the last two years, bringing the total species reported for China to nearly 290.…”

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).…”

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

“…Chen Yilin (Chen et al 2008) reported 228 known species of Impatiens in China, of which 187 are endemic, while Yu Shengxiang (Yu 2012) reported the discovery of approximately 270 species in China. With the expansion of our research, in recent years numerous new species have been successively found and documented (Peng et al 2019, Zhang et al 2020a, b), with over 20 new species discovered between 2019 and 2021 (Xia et al 2019a, b, Gan and Li 2020a, b, Gan et al 2020, Lu et al 2020, Peng et al 2020, 2021a, b, Qin et al 2020, Wang et al 2020a, Xue et al 2020, Zhang et al 2020a, Zou et al 2020, Liao et al 2021, Song et al 2021a, b, c). At present, approximately 290 species of Impatiens are documented from China.…”
