Sorbus aucuparia L.

Pomaceous Fruit: European Mountain Ash, Rowan



Transversal section

  Diffuse- to slightly semi-ring-porous. Numerous pores, mostly solitary, relatively small, more or less regularly distributed. Growth ring boundaries distinct to indistinct, dependent on distribution of pores, which varies with growth conditions. Ground tissue fibres relatively thick-walled. Diffuse apotracheal parenchyma, rarely in short, uniseriate tangential bands. Sometimes gum deposits in heartwood vessels.

Radial section

  Simple perforation plates. Fine spiral thickenings occur occasionally in the vessels, often only in vessel element tails. Rays almost homogeneous, often with one row of square marginal cells. Both prismatic crystals and druses sometimes present in rays or in axial parenchyma (idioblasts). Fibre-tracheids present, libriform fibres absent.

Tangential section

  Rays generally bi- to triseriate. Ray cells regularly round to slightly oval elongated. Average ray height: 5 to 20 cells.

Key characters

  Diffuse- to semi-ring-porous. Rays generally biseriate, almost homogeneous. Simple perforation plates. Vessel pits opposite, in horizontal rows.


  The wood of the Sorbus species cannot be differentiated on the basis of wood anatomy.
