Structure

Growth rings absent but the presence of parenchyma bands may simulate growth rings feature.
Vessels with simple perforation; moderately large to large; few are solitary with the majority in radial pairs or multiples of up to 4; occasionally radial multiples of 5 to 8 may be found. Clustering of pores is fairly common and pores distributed without any arrangement. Tyloses are abundant. Vessel lines are conspicuously present as coarse scratches on the longitudinal surface.
