Types

Original diagnosis/description

Growth ring boundaries distinct. Transition from earlywood to latewood gradual. Traumatic resin canals present. Tracheids polygonal. Normal axial resin canals absent. Axial parenchyma very rare and marginal and diffuse. Rays uniseriate, rarely biseriate, or occasionally partly biseriate. Rays’ height mostly 8–20 (1–62) cells. In some samples rays with horizontal resin canals are common. Tracheid pitting in radial walls (in earlywood) is uniseriate and biseriate. Scalloped tori very clearly visible in tracheidal pits on the radial walls. Rays heterogeneous and irregular shaped ray tracheids common in 1–2 rows. Horizontal and end walls of ray parenchyma cells are distinctly pitted. Cross-field pitting is cupressoid and taxodioid with 2–5 pits per cross-field. Tracheid pits on radial walls common, contiguous and slightly araucarioid at the tips of tracheids.

Etymology
