Figure 1: Location of the 38 source populations of A. kamchatica in central Japan. Subspecies were kamchatica (perennial, wide altitudinal range) and kawasakiana (annual, lowland), and are shown by solid and open points, respectively. The numbers correspond to the population numbers in Table 1. Mountain chains and isolated peaks higher than 2000 m in altitude around the populations are depicted by grey lines and grey circles. Seashores, lakeshores, and prefectural borders are represented by solid lines.
