ABSTRACT	I investigated the spatial distribution of genotypes among eight populations of Hosta minor and 19 populations of H. capitata from Korea using spatial autocorrelation analysis of enzyme polymorphisms. Both species are insect-pollinated, herbaceous perennials. Among 162 cases calculated for six distance classes among populations of both species, Moran's I was significant for 20 (12%) cases in H. minor and for 35 (21.6%) in H. capitata, respectively. In addition, the number of significant overall correlograms was different from each species (33.3%, 9/27 in H. minor vs. 11.1%, 3/27 in H. capitata). Eleven of 16 significant negative autocorrelations were observed for H. capitata in the longer distance classes (ca. 111_235 km boundary). On the other hand, no distinct trend with respect to distance was detected among populations of H. minor. The results of the study indicate that the level of gene flow among abundant, contiguous local populations of H. minor via winged seeds is higher than that of H. capitata, partly resulting from different distribution patterns and natural habitats of both species.
