Salix reticulata L.

Creeping willows: Netted Willow, Net-leaved Willow

Salicaceae

 
 

Transversal section

   
  Diffuse- to semi-ring-porous. Pores solitary or in short radial files of 2 to 3 pores, occasionally clustered. Growth ring boundaries more or less distinct, depending on abruptness of the pore size transition. Sparse apotracheal parenchyma, occasionally terminal parenchyma in uniseriate, discontinuous bands.
 
 

Radial section

   
  Simple perforation plates. Heterogeneous rays with one to two rows of square and upright, mostly marginal cells. Large, simple ray-vessel pits. Libriform fibres present.
 
 

Tangential section

   
  Uniseriate, very rare biseriate, rays. Ray height: 5 to 15, rare up to 30 cells.
 
 

Key characters

   
  Diffuse- to semi-ring-porous. Uniseriate heterogeneous rays. Large ray-vessel pits.
 
 

Remarks

   
  The wood of the creeping willows resembles on the basis of characteristics features (heterogeneous rays and large pits) the other species of Salix. The distinction, particularly of branch wood, between creeping, bush, and tree species is possible in only a limited number of cases, e.g. for S. retusa (semi-ring-porous, pores densily packed, pores in clusters), S. herbacea (similar to S. retusa, in subterranean stems often root-like structure), S. reticulata (pores relatively widely spaced, solitary or in small clusters).
