ABSTRACT	Ninety-nine, 75, and 71 individuals were mapped and leaf samples were collected from three populations (10 × 15-m plot [MIM], 40 × 50-m plot [KOS], and 15 × 20-m plot [NOD]) of Hemerocallis hakuunensis to determine if spatial genetic structure existed in the three populations in terms of their ecological characteristics. A substantial spatial genetic structuring was found in MIM, whereas a weak structure was observed in NOD and KOS. Moran's I values were significantly different from the expected value (-0.010) in 137 (52.7%) of 260 cases in MIM, whereas significant Moran's I values were observed in 25 (10.4%) of 240 cases and 55 (20.4%) of 270 cases in NOD and KOS, respectively. The approximate minimum patch width also varied among the three populations: NOD = 3 m, MIM = 5 m, and KOS = 10 m. The differences in patch width may result from the differences in density, colonization history, thinning processes or any of a number of other factors among populations.
