- Diagnosis
- Growth rings are distinct. Pits in radial tracheid walls are uniseriate, circular or elliptic, 12–18 × 16–20(21) μm in size. Crassulae are present occasionally between elliptic pits. Trabeculae occur occasionally in tracheids. Pits in tangential tracheid walls are absent. Uniseriate rays are of 1–9(15) cells
high. Ray tracheid walls are unevenly dentate, some times reticulate. Normal vertical resin canals are lined by 8–10 thin'walled epithelial cells. Horizontal
resin canals lined by 6–8 thin-walled epithelial cells occur in biseriate rays with equal (up to 3–8 cell rows) uniseriate ends. Cross-field pits in earlywood
are window-like, 12–16 × 12–20 μm in size, with one (rarely two) pits per cross'field; in latewood, the cross-field pits are pinoid, 6 × 12 μm in size, with one pit per cross-field.
