1. The distribution area formerly known for Kalimeris incisa DC. in Japan was from Kyushu to Kinki District of Honshu. The present investigation revealed that the distribution of this species extends eastward into the western and southern lowlands of Chubu District in central Honshu.2. At many localities within the distribution area, K. incisa was growing together with a morphologically similar heptaploid sepcies K. yomena. But K. incisa seemed to prefer habitats a little drier than those of K. yomena.3. Except some insular and periferal populations, K. incisa showed a high degree of individual variability, and the range of variation at any one locality closely approximated that which occurs over the entire species range in Japan.4. The results of a chromosome count revealed that K. incisa in Japan is nearly stable as an octoploid species with 2n=72. It showed, however, a peculiar pattern of variation in chromosome number that the frequency of aneuploids with 2n=71 or lower chromosome numbers is much higher than that of aneuploids with 2n=73 or higher chromosome numbers.5. Some clones were found to include one or two large chromosomes in their somatic chromosome complements. Those chromosomes are presumably derived from a species of Aster.
