Diagnosis
Wood ring-porous. Growth rings distinct. Earlywood vessels in 1–2 almost continuous tangential bands, latewood vessels in wavy tangential to diagonal (oblique) bands of 3–6 vessels. Early wood vessels 66–176×120–218 µm in diameter, late wood vessels 19–30 µm in diameter. Vessel elements 160–288 µm in length. Vessel walls 3.0–3.5 µm thick. Simple perforation plates. Intervessel pitting alternate, with up to 20 bordered pits per width of vessel; pits 6–10 µm in diameter. Helical thickenings in narrow vessel elements, also in vascular tracheids. Thin-walled tyloses common in earlywood vessels. Axial parenchyma scanty paratracheal and marginal; parenchyma strands of 4–6 cells. Fibre walls 4.0–4.5 µm thick. Rays uniseriate to 6-seriate, 1–50 cells high, homocellular, composed of procumbent cells; multiseriate rays sometime with uniseriate ends of 1–4 cells. Storied structures absent.
