- Diagnosis
- Growth rings distinct. Araucarianwood type. Radial
pitting of earlywood tracheids contiguous, predominantly biseriate-hexagonal, uniseriate flattened with biseriate
hexagonal-alternate portions and uniseriate-flattened (laterally
compressed with a rectangular shape); some bi-triseriate
hexagonal-alternate and uniseriate flattened with biseriate square
shape and opposite. Radial pitting of latewood tracheids
contiguous, uni-biseriate, circular and alternate. Cross-fields
pitting araucarioid, two to eight circular pits, frequency range
five to six pits. Rays homocellular, mostly uniseriate and the
average height is medium. Axial parenchyma diffuse.
