FALSE ACACIA 



G.N. 1691 



May be confused with: 



Laburnum [thyloses few: rays 

 high in tangential section (micro- 

 scope)]. 



Elms (rays dark-coloured : paren- 

 chyma cells alternate). 



Mulberry [wood greenish-white 

 turning deep chocolate-brown. 

 Parenchyma-cells (microscope) al- 

 ternate. To the naked eye the 

 parenchyma (a) is often dark- 

 coloured : thyloses few or wanting]. 



May be distinguished by: 



Vessels choked with thyloses, 

 rays low in tangential section. 



Rays light-coloured : parenchyma 

 cells in palisade. 



All vessels choked with thyloses, 

 which are visible with the lens. 

 Wood greenish-white, darkening 

 considerably to a brown (hazel) 

 colour but by no means so deeply 

 and always remaining relieved by 

 alternate stripes of a lighter 

 colour.
