AND BARK. 



I AM now going 

 to tell you a little 

 more about the 

 fibro - vascular 

 bundles ; so let 

 us look at them 

 in a buttercup 

 plant, or in a leafy 

 branch of bush or 

 tree, such as the 

 sycamore or 

 flowering currant 

 The fibro-vascular 

 bundles which 

 have grown up 

 within the main 

 stem of the herb 

 or tree, have 

 branched out with and within its branches, and you 

 can see them as they branch for the last time and 

 appear as veins in the blades of the leaves.
