In my context wall 4 is new growth on the external side of the wound (the outside or bark side). |

Thanks for your diagrams and photos, Sean and Ekka. A big improvement on my words. I had forgotten just how good the watercolour illustations are.
Ekka, if you open the link in your post #29 and scroll down to near the bottom of the first piece of text, you'll find a quote by Dr Shigo.
?Do not confuse CODIT with WOUND CLOSURE. CODIT and WOUND CLOSURE are two different processes. The walls are model figures to simplify the understanding of the succession of micro-organisms. You will not see the walls?.
I think Azrael's photos of Figs should be looked at again (Post #14).
I think many arborists have seen the indicators of Wall 4s. Perhaps they didn?t recognise them.
When you are cutting up a section of tree (not a palm), there are often rings of kino (or resin or latex).
However imperfect or indistinct the rings are, they are highly likely to be indicators of previous Wall 4s, showing that the tree was wounded when it was that diameter. There might not be other indicators of compartmentalisation: - sometimes you will see a stain showing where Walls 1 and 2 were. Sometimes you might see a vaguely triangular shape showing a Wall 3.
So Ekka you were on the right track back in Post #17 when you mentioned latex.
Perhaps re-read other posts #16, #19 and #23.
