- Diagnosis
- Growth rings are distinct. Pits on the
radial walls of tracheids are abundant, uniseriate, in the
first tracheids of early wood there are biseriate opposite
pits. Pits are (10)12–18(24) μm in diameter. Pits on the
tangential walls of tracheids are uniseriate, 2.5–3 μm in
diameter. Uniseriate rays are 1–30(50) cells high, occasionally with 1–5 layers of biseriate cells. Vertical resin
canals are encircled by 8–10(12), horizontal ones – by
5–6(7) epithelial cells. Horizontal resin canals occur in
bi-triseriate, triseriate and tri-quadriseriate rays with
long equal and unequal uniseriate ends. There are 1–6
piceoid pits per cross-fields, 3–4 μm in diameter.
