- Diagnosis
- Tracheidoxyl without growth rings,
without any resin ducts, having thick-walled tracheids
with rounded lumina, rd/tgd=20-30/20-35 μm, density
1750-1850 on sq.mm, tangential walls unpitted,
araucarian radial pitting partially covering the wall,
uni- or biseriate, usually contiguous, with round to
slightly flattened or polygonal borders of 17-18.6 μm
in diameter, tilted elliptic apertured, striated walls
without crassulae, with trabeculae. Wood
parenchyma absent. Uniseriate rays of 1-23 cells
high, with short biseriate storeys, density of 8-12 rays
on tangential millimeter, homogeneous,
homocellular, thick-walled ray-cells, araucarioid
cross fields with 1-7 or more alternate contiguous
araucarioid pits on 1-2-3 horizontal rows.
