Sambucus nigra L.

Elder, Alpine Elder, Bow Tree

Caprifoliaceae

 
 

Transversal section

   
  Semi-ring- to diffuse-porous, thin-walled pores, grouped in oblique and tangential clusters. Occasionally thin-walled tyloses in pores. Growth-ring boundaries generally distinct, marked by a conspicuous difference in size of earlywood and latewood pores and often marginal bands of thin-walled vascular tracheids. Parenchyma apotracheal.
 
 

Radial section

   
  Simple perforation plates. Heterogeneous rays, generally with 1 to 2 (occasionally up to 5) rows of square and upright sheath cells. Vessel pits round, ray-vessel pits large and more oval. Libriform fibres present, fibre tracheids absent. In the latewood often a wide band of vascular tracheids.
 
 

Tangential section

   
  Rays generally bi- to 4-seriate, with sheath cells. Ray height 10 to 30 cells.
 
 

Key characters

   
  Semi-ring- to diffuse-porous. Pores in clusters. Rays heterogeneous, with sheath cells. Often a band of vascular tracheids in the end of latewood.
 
 

Remarks

   
  The wood of the two species S. nigra and S. racemosa cannot be differentiated on the basis of their wood anatomy.
