This study shows the differences in fibre characteristics of Robinia pseudoacacia growing in Hungary and Sclerocarya birrea growing in Sudan. Also, the analysis and comparison of the growing zone widths (the vessel lumina diameters in the earlywood and the wave amplitudes of the wavy vessel bands) for Ulmus minor were studied. The mean values of fibre length (mm), lumen diameter (µm), fibre diameter (µm), and cell wall thickness (µm) of R. pseudoacacia were 0.83, 13.18, 18.35, and 513, respectively. While they were 0.82, 26.37, 18.01, and 8.36 for S. birrea. The results also show that the fibre characteristics do not change gradually from pith to bark. The anatomical studies of Ulmus minor revealed significantly different results in the latewood widths, between 0.775 mm and 2.776 mm. Most vessels in the earlywood are below 0.721 mm diameter. The latewood vessel band amplitudes are mostly between 0.138 and 0.230 mm.
