The specie of Fagacea in the compound of 27 shrines in Onoda-shi, 22 shrines in Sanyo-cho, and 51 shrines in Mine-shi was invesitgated. Fifteen species belonging to four genera, 10 broad-leaf evergreen species and 5 broadleaf deciduous species, were identified: Quercus acuta (in 4 shrines), Q.glauca (in 59), Q.myrsinaefolia (in 18), Q.salicina (in 3), Q.sessilifolia (in 6), Q.gllva (in 1), Lithocarpus edulis (in 2), L.glabr (in 7), Castanopsis cuspidata (in 35), C.cuspidata. sieboldii (in 3), Q.variabilis (in 2), Q.acutissima (in 8), Q.serrata (in 31), Q.aliena (in 1), and Castanea crenata (in 19). In this area, Q.glauca is a dominant and Q.serrata and C.cuspidata are common. The number of species in a shrine was 2.0 on the average. However, there are some differences in the kind of species and frequency among dsitricts. Mine-shi, the moutainside, is most abundant in the kind and most in the number of species a shirine. Those values in Mine-shi were about twice as much as those in the coastal district, Onoda-shi, respectively. The habitat of L.glabr observed in 7 shirines ranged north and south in Mine-shi. L.glabr is a rare in Yamaguchi and has been common only the in eastern area in Yamaguchi Prefecture.
