The results are as follows. (1) The micell angle of the cell wall of Moso bamboo distributed scatteringly near the ground height and the top, but in the middle part the distribution is in a close range around the b-axis. (2) In Akamatsu wood, the distribution of the micell angle of the spring wood was wider than that in the summer wood. (3) Mean micell angle calculated from (040) arc was sharper than the one calculated from (002) arc by 3°～5°, and it seemed that there is a linearity between the values of the two arcs. (4) It may be said that the micell angle depends greatly on the cell length, and the relationship between the micell length and the mean micell angle corresponds to the relationship between the tracheid length and the mean micell angle. (5) No significant difference is observed from the ground to the top of Moso bamboo for the degree of crystallinity.
