strange tissue on tree

[zyrell]

Hello everyone,

 

I found this strange tissue on a large Eucalyptus, does anyone know what kind of tissue is it?

 

Thank you

They may be sphaeroblasts

 

Cell tissue that doesn't form buds and just keeps on deviding and expanding instead. In some species they detach from the trunk.

I have a vague feeling that sphaeroblast tissue, being bud-free, is capable of rooting that branch tissue of the same tree isn't. There may therefore also be a gravitropic tendency to the growth, in other words favouring downward growth.

 

Perhaps this tendency is a throwback in evolution to ancestral species that could and would produce downward growing sphaeroblasts as a means of vegetative reproduction and spread.

new one on me

I've often seen them on older Sweet Chestnut where they become quite large and prominent. Not seen them on many other trees, but will be looking out for them now.

Me too, because as I look into it I dicover that sphaeroblast tissue is often juvenile in character and rich in adventitious material.

Not sure if it's me being blind but that tree looks a London plane?

I wonder if a section was cut from the tree and placed on the soil surface or a planting medium, It would propagate? If so how small a section would be required to do so.

well it does look similar but we cant see the leaves or tree form - It would be obvious then

Thank you for the reply.

The tree is not in UK:001_smile:~~~

It is a Eucalyptus camaldulensis
