- Diagnosis
- Growth ring boundaries distinct with 2-3 rows of flattened latewood tracheids. False rings commonly present. Transition from earlywood to latewood indistinct. Tracheids generally circular, and intercellular spaces clearly obvious and occur throughout the wood. Normal axial resin canals absent. Axial parenchyma appears both diffuse (in the transition from early
wood to latewood and within the latewood itself) and tangentially zonate. Rays uniseriate, and sometimes partly biseriate. Ray height is 1-6 (max.16) cells. Tracheidal pits on tangential walls common and 1-2 seriate, irregular or slightly alternate. The rays with one cell height conspicuously longer. Transverse end walls of axial parenchyma cells are nodular and smooth. Ray tracheids absent. End walls of ray parenchyma cells nodular and smooth, horizontal walls of rays sparsely pitted. Tracheid pitting in radial walls of the early wood is uniseriate and biseriate, opposite, frequent, contiguous, and sometimes spaced. Cross-field pitting is cupressoid with 2–3 (-5) pits per cross-field.
