An Illustrated Investigation of the Names and Realities of Plants

Original Chinese title: Zhiwu Ming Shi Tu Kao. This seminal work was authored by the scholar-official Wu Qijun and published posthumously around 1848. It is regarded as one of the most significant botanical texts of the Qing Dynasty, marking a transition toward more modern, observation-based scientific categorization in China.

The term "Names and Realities" (mingshi) refers to a long-standing philosophical and scientific tradition in China of ensuring that the name of an object accurately corresponds to its physical existence—an essential task for identifying medicinal plants.
