Laburnum anagyroides Med.

Golden Chain



Transversal section

  Ring-porous. Structure very variable. Earlywood pore ring rather densely packed. Pores and vascular-tracheids always in small or large groups in the latewood, paratracheal parenchyma associated with pore patches and vascular tracheids orientated in oblique to tangential bands (occasionally marginal), often as well as growth ring boundaries festoon-like. Ground tissue cell walls of medium to higher thickness. Gumdeposits in the heartwood vessels. Rays often flare conspicuously at the growth ring boundaries.

Radial section

  Simple perforation plates. Spiral thickenings in latewood vessels. Rays homogeneous to slightly heterogeneous, with sqare marginal cells. Vestured pits. Libriform fibres and vascular tracheids, no fibre-tracheids.

Tangential section

  Rays generally 5- to 7-seriate, occasionally wider than 7 cells. Rays rarely higher than 1 mm, sometimes with sheath cells. Parenchyma cells fusiform, storied.

Key characters

  Ring-porous. Growth ring boundaries festoon-like. Pores, vascular tracheids and parenchyma in oblique to tangential groups. Rays often over 5-seriate, flare at growth ring boundaries. Spiral thickenings.


  The wood of the two species L. anagyroides and L. alpinum cannot be differentiated on the basis of their wood anatomy.
