- Diagnosis
- Growth rings distinct. Pits on the radial walls of tracheids uniseriate or biseriate (predominant); opposite. Crassulae are present. Circular pits are
18–21 μm in diameter, elliptic pits are (15)18–21(24) × 24–27(30) μm in dimension. Pits on the tangential walls of tracheids uniseriate and biseriate, (6)9 μm in diameter. Axial parenchyma with smooth transverse walls. Uniseriate rays 1–30(40) cells high. Inner walls of ray tracheids smooth. Vertical resin canals are encircled by 7–10 and horizontal ones – by 6–10 thick-walled epithelial cells. Horizontal resin canals occur in biseriate rays; uniseriate ends are equal (up to 15 cells long) or unequal: short end consists of 3–8 and long end – of 7–16(25) cells. Piceoid pits 1–6(9) per cross-field,
5 μm in diameter.
