Impatiens maolanensis is similar to I. auriculata (Figs 2 A – G, 3 E – H, 4 D – F), I. liboensis (Figs 2 H – N, 3 I – L, 4 G – I) and I. tianlinensis (Zeng et al. 2015, 2016) but its characteristics are significantly different from the latter three species in terms of orange-red flowers, thick fibrous root, stem with leaf scars and nodes, petioles, sessile or nearly sessile, bracts, outer lateral sepals, dorsal petal, lower sepal, and fruit color (Table 1).	en	Li, Bai-Zhu, Wen, Qin-Ying, Wang, Jin-Dong, Huang, Xiao-Xiang, Xiong, Zhi-Bin, Deng, Zhi-Juan, Yi, Yin, Tang, Xiao-Xin (2025): Impatiens maolanensis (Balsaminaceae), a new species of Impatiens in a tiankeng from Guizhou, China.
