Figure 105. — A transverse section at the junction of the inner and outer 

 cortex, — the latter at the top half of the plate. The bast 

 fibres are the rectangular figures extending in lines from 

 left to right, whilst ihe parenchymatous cells between these, 

 seen clearly in the lower half, have their radial walls length- 

 ened. The band of thin-walled, compressed cells running 

 through the centre of plate from left to right is a layer 

 of periderm. The dark brown band shows the contents 

 of the outer cortex parenchymatous cells. Unstained.
