- Diagnosis
- Growth rings distinct, transition from early wood tolate wood gradual. Pits in the radial walls of tracheids unis-eriate, occasionally biseriate. Pits in the tangential walls oftracheids rare, uniseriate, circular. Axial parenchyma absent.Uniseriate rays 1–16 cells high, sometimes partially biseri-ate (1–3 cells wide). Fusiform rays 2–4-seriate. Ray tracheidspredominantly in two marginal rows. Horizontal walls of raytracheids weakly dentate to smooth. Both axial and radial resincanals present, epithelial cells thin-walled, traumatic resin canalsabsent. Cross-field pits pinoid and taxodioid, 3.0–12.0 m indiameter, 1–4 (6) per cross-field, usually in 1–2 horizontalrows.
