- Diagnosis
- Wood diffuse-porous to semi-ringporous. Growth rings distinct, marked by 24 rows of flattened fibers and parenchyma. Vessels solitary, in radial multiples or clusters of 2–5 vessels. Perforation plates both simple and scalariform, the later with 4–20 bars. Intervessel pits crowded alternate, hexagonal, about 3.6–4.8(6) mkm. Vessel-ray pits small, rounded or some horizontally elongate. Axial parenchyma metatracheal – in short wavy tangential bands of 1(2) cells wide and terminal; in longitudinal sections in strand of up to 6
− 8 cells. Rays heterocellular; uni- to 4-seriate, the later with 1–2 layers of 5-seriate cells. Uniseriate rays 2 − 42 cells and multiseriate ones 7–103 cells high. Multiseriate rays with uniseriate ends of up to 23 cells or only of 2–3 cells. Pith flects are present. Pith solid, not chambered.
