Transversal section |

Diffuse- to semi-ring-porous. Pores often in radially oriented files and clusters. Pores slightly polygonal. Growth ring boundaries marked by 2 to 3 rows of thick-walled, radially flattened cells and distinctly flaring rays. Apotracheal parenchyma generally in short, uniseriate, oblique to tangential bands, often also terminal. |
