In the previous paper Tanaka, one of the writers, reported the developing process of the lateral roots growing from the main root in the leguminous crop plants, which according to its developing condition could be classified into three types, namely alfalfa, vetch and intermediate types. In this report the main roots of crops belonging to those three types were anatomically observed and compared with each other. 1. In alfalfa type, initials of lateral roots are formed adjoining each other, and also appear at varying times (Fig. 1, B-I〜VI, C). Consequently, the formation of meristems for rooting was recognized on the main root (Fig. 2, D-I, II). 2. The development of the medullary ray of the root differ with the crop and type (Fig. 3, E-I〜V), and is considered to have a close relation with the development of lateral roots. 3. It was also recognized that the secondary thickening growth of the root also differs with the crop and type (Fig. 4). Generally, the alfalfa type showed a tendency to grow more in thickness than the vetch type.
