  Diffuse-porous. Growth ring boundaries rather distinct, marked by 2 to 4 rows of radially flattened cells. According to some growth conditions these boundaries can be rather indistinct. Pores rather sparsely scattered, solitary, in radial multiples of 2 to 4 pores and in clusters. Pore size varies highly from one growing site to the other. Diffuse, sparse apotracheal parenchyma.

Radial section

  Scalariform perforation plates with 10 to 15 (sometimes up to 25) bars. Homogeneous rays, occasionally square marginal cells. Ray-vessel pits numerous and extremely small. Libriform fibres present, fibre-tracheids absent.

Tangential section

  Rays 2- to 4-seriate, also often uniseriate. Average ray height: 10 to 25 cells.
