Lespedeza species have been widely used not only as plant resources for bark, leaves and honey, but also as erosion control materials. This study was carried out to investigate the structural and wood fiber characteristics in order to obtain basic information for the utilization of the wood. The wood structure was investigated for 10 selected species and the wood fiber, for the 5 selected species among Lespedeza species distributed all over the country. The following results were obtained. In the cross section, campylotropis showed ray diffuse porous wood, L. bicolor, L. cyrtobotrya, L. thunbergii var. intermedia, diffuse porous wood, and L. tomentella, L. angustifolioides, L. maritima, L. robusta, L. patentibicolor, ring porous wood. The maximum diameter of a single vessel ranged 66-123 μ in all species. Campylotropis showed the most number of vessels, L. angustifolioides, the least. The number of ray per mm ranged 7-22, Campylotropis showed the most number of rays, L. angustifolioides, the least. In the radial section the average length of vessel ranged 121-250 μ in all species. L. thunbergii oar. intermedia showed the longest vessel, L. tomentella, the shortest. In tangential section the average width of the uniseriate ray ranged 9.2-14.7 μ, that of the multiseriate ray, 19.2-42.1 μ. The average height of the uniseriate ray ranged 143.0-1162.0 μ. The width of fiber ranged 10.12-13.61 μ, L. maximowiczii showed the narrowest fiber, L. thunbergii oar. intermedia, the widest, the thickness of fiber wall ranged 2.93-3.71μ in the five species. L. maximowiczii showed the moss: thin fiber wall, L. thunbergii var. intermedia, the thickest. L. cyrtobotrya showed the difference in the size of fiber between the shade and the sunny sites but L. maximowiczii showed no difference. There was significant difference in fiber length, fiber width and wall thickness between L. cyrtobotrya and L. maximowiczii.
