Pseudo-sections constructed from the SRX-ray μCT dataset from SPring-8 for male deity 8 (f in Table 1). a cross-section, b, c, e tangential section, d: radial section. b and e are magnified images of tangential sections. The sample is typical diffuse porous wood (a) with a simple perforation plate (e). In the radial and tangential sections, widely spaced spiral thickenings (arrowhead in b) are observed. In the tangential section, an alternate arrangement of intervessel pitting is clearly observed (b) and prismatic crystals exist in chambered AP cells (d)
