Radial section

  Long scalariform perforation plates generally with more than 25 bars. Spiral thickenings in vessels and fibre-tracheids. Bordered pits in extremities often scalariform, in vessels from bordered pits to scalariform perforation plates, all transition forms present. Rays conspicuously heterogeneous, many rows of upright marginal cells. Fibre tracheids present.

Tangential section

  Rays generally uni- to biseriate, rarely 3-seriate. Cells of uniseriate and sheath cells of multiseriate rays axially oval to rectangular, inner cells of multiseriate rays smaller. Average height of biseriate rays 8 to 15 cells.

Key characters

  Diffuse-porous. Rays conspicuously heterogeneous. Long scalariform perforation plates with many bars.


  Viburnum lantana can be differentiated from Viburnum opulus by presence of spiral thickenings in the fibre-tracheids.
