- Diffuse porous wood, distinct growth rings limited
by 1–2 cells wide marginal parenchyma; vessel elements solitary,
multiple radials of 2–4 and few clusters, 3–8/mm2, 150 μm in
tangential diameter, perforation plate simple, intervascular pits
oval–polygonal and alternate, 6 μm in diameter, ray-vessel element
pits opposite, ovoid, 7 μm in diameter; vasicentric tracheids 60 μm in
diameter, opposite pits; septate (60 %) and non septate (40%)
libriform fibres, with rhomboidal crystals; rays mainly homogeneous,
mostly biseriated; vasicentric paratracheal and marginal and diffuse
apotracheal parenchyma; oil cells.
