to opposite intervessel pits; heterocellular, (1) 2–4 (6) seriate rays;
non-septate fibers with distinctly bordered pits; diffuse and diffuse-inaggregate
apotracheal axial parenchyma, axial parenchyma 8–12 cells
per strand; crystals in rays cells and in chambered axial parenchyma
cells; vascular tracheids probably present.
