Abstract Since the rare earth elements (REE) are most informative as isomorphic replacements of Ca2+ in organisms, we analyzed these elements in 142 fern leaves collected from several sampling sites in Japan by instrumental neutron activation analysis (INAA), and the correlation between the REE and Ca contents was examined. In most cases, between any particular REE and the Ca contents, the correlation in the logarithmic scattering diagram was expressed as a single line parallel to the vertical (Y) axis. However, the detailed analysis of the diagrams characterized with respect to the sampling site revealed that the 142 ferns could be separated into two or three groups on the basis of their different REE/Ca ratios. The sampling sites where the different REE/Ca ratios were observed completely agreed with those found in the preceding report, i.e., regarding the unusual correlation between Eu and the other REEs.
