- Diagnosis
- Wood type (tracheid radial pitting) is araucarian (100% of the contiguous pits are araucarioid). Pits are araucarioid,
uniseriate, flattened, and circular; alternate biseriate, circular,
and hexagonal; uniseriate, partially biseriate, alternate, circular,
hexagonal-flattened; and opposite circular, hexagonal-flattened in
a pair or several pairs (japonicum type); and triseriate and bitriseriate,
alternate circular and hexagonal. Cross-fields are araucarioid,
with 2–14, 20 pits, circular, with elliptical or sometimes
circular apertures, whose frequency range is 6–8 pits, arranged in
disordered groups or crown-shaped or some in two or four horizontal
rows. The rays are homogeneous, mostly uniseriate, and
the height in number of cells is 1–16, 20.
