We investigated leaf hair type of Quercus species in natural mixed stand at foot of Mihara Mountain and from the result of classification on based on their hair types using, it was found that middle types of Mizunara, Konara and Kashiwa are about 25% of 203 individuals. Following this investigation, we measured 14 morphological traits of them with dijitizer. For further analysis on the traits of hair types of three species, we examined Mizukonara (Q. crispuloserrata), a middle type between Mizunara and Konara, Kashiwamodoki (Q. × anguste-lepidota) between Mizunara and Kashiwa, and Kogashiwa (Q. × takatorensis) between Konara and Kashiwa. The result from an analysis of variance on the three species and those middle species on 14 traits indicated that there were significant difference among 3 species and those middle types at many traits concerned in discerment of species. It was shown that these significant result of middle types lies of types between the two species. As a result, became clear that the middle types of two species were present.
