Abstract
Objectives : This paper aims to solve difficulties surrounding the verses related to lobes of liver in the 『Yixuerumen』. Methods : First, relevant verses were selected from the 『Yixuerumen』, then compared to texts from which they had originated. The differences and contrarieties between the texts were resolved through the perspective of plant taxonomy. Results : Wangbing's 'buye(布葉)' was taken as the seed leaf of the dicotyledonous plant and corrected to 'daye(大葉)' by Li Chan. The expression 'Yixiaoye(一小葉)' was understood as describing the many main leaves that look like one big leaf, which grow in between the seed leaves. 『Nanjing』's interpretation of there being three leaves on the left, and four on the right describes the leaf pattern that grows in alternation. Conclusions : Through analysis of the verses related to lobes of liver in the 『Yixuerumen』, we can presume that Li Chan had the knowledge and understanding required in plant taxonomy such as characteristics of a dicotyledonous plant and phyllotaxis.
