Populus tremula L.

Aspen

Salicaceae

 
 

Transversal section

   
  Diffuse- to semi-ring-porous. Pores solitary or in radial groups or in radial rows of 2 to 3 multiples. Growth ring boundaries more or less distinct, depending on pore size transition from earlywood to latewood. Sparse, diffuse apotracheal parenchyma, occasionally in uniseriate, discontinuous terminal bands.
 
 

Radial section

   
  Homogeneous rays, rare with square marginal cells. Simple perforation plates. Extremely large, simple ray-vessel pits. Libriform fibres present, fibre-tracheids absent.
 
 

Tangential section

   
  Rays uniseriate, ray cells axial oval. Average ray height: 10 to 30 cells.
 
 

Key characters

   
  Diffuse-porous. Uniseriate, homogeneous rays. Large ray-vessel pits.
 
 

Remarks

   
  The Populus species cannot be distinguished from each other on the basis of their wood anatomy. Similar to Salix. When square ray cells are present, it is difficult to distinguish from species of the genus Salix.
