We investigated the distribution of indigenous and exotic dandelions and their growing environmental conditions in Mikajima district, Tokorozawa, Saitama Prefecture in Japan. In the overall 167 investigated points in Mikajima district, colonies with indigenous dandelion were 16 (9.6%), exotic dandelion were 132 (79.9%), and both dandelions were 17 (10.2%). There were many other exotic plants in the communities with dandelion colonies. From the comparison of soil properties at each colony, the indigenous dandelion grew in weak acidic soil and the exotic dandelion grew in the slightly alkaline soil. Additionally, exotic dandelion distributed widely in the soil with low to high water contents and wide range of soil hardness. Those distribution characteristics of exotic dandelion indicated that this species easily invaded and distributed in urban area. (Waseda Journal of Human Sciences, 18 (1) : 31-36, 2005)
