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.
