Distribution patterns of randomly sampled 9 vascular plant species which show 'less widespread' distribution in the Nagano prefecutre, central Japan (Fig. 11-19), were compared each other to detect 'singular point' of distribution by superposing their contours of distribution ares. A heavy overlap of contour lines was detected in the western central part of the prefecture, Shimashima-dani (Fig. 20). This method will be useful for numerical treatment of distributional study.
