  Ring-porous to semi-ring-porous. Pores generally solitary and relatively widely spaced. Growth ring boundaries very distinct. Parenchyrna apotracheal, diffuse, rarely paratracheal. Ground tissue cells thick-walled. Pith: In the pith small groups and rows of thick-walled cells are situated between large thin-walled cells.

Radial section

  Simple perforation plates. Spiral thickenings in vessels. Uniseriate rays composed of upright cells. Heterogeneous, multiseriate rays with numerous rows of upright and square marginal cells. Only fibre-tracheids, no libriform fibres present. Prismatic crystals in ray cells.
