Southwestern Shanxi ( Jiexiu, Xiaxian ), southern Shaanxi, southern Gansu, Jiangsu, Anhui, Zhejiang, Jiangxi ( Lushan ), Taiwan, Henan, Hubei, Hunan, northern Guangdong ( Ruyuan ), Sichuan, Guizhou, southwestern and southeastern Yunnan ( Fengqing, Xichou ) and Tibet. Born in forest wetland or ditch wetland, elevation 500-2900 meters. Nepal, Bhutan, Sikkim, India, Vietnam, Thailand and Japan are also distributed. Type specimens from India.

 

This species is a widespread species. The shape of the lateral lobes of the lip lobes and the fleshy protrusions at the base of the middle lobes have changed greatly, and the narrow wings on the upper part of the stamen column also have similar conditions. Some scholars classified the types of small and smooth fleshy protrusions on the lips and narrow wings on the upper abdomen of the column as species or varieties. However, according to the Chinese specimens, this feature is not only transitional, but also overlapping and difficult to separate, so we do not divide, still regarded as the same species.
