In this study, the resource distribution, morphological characteristics, artificial cultivation and market circulation of Paris Polyphylla var. yunnanensis and its polygerm varieties in Yunnan were investigated by referring to the research literature, field investigation and our planting experience. It is found that P. polyphylla var. yunnanensis is widely distributed in Yunnan Province, realizing large-scale artificial cultivation, while the wild resources of polygerm varieties are almost on the verge of extinction and are in urgent need of protection.
