Why is this happening to my tree?

Box elder grafted with ???

Wow! Thanks a bunch for that information Alec, helps me understand a lot.

Cheers again

Cornus and Sorbus are so distantly related that grafting or hybridisation is unimaginable. They are both Eudicots but that's where the similarity ends. Compatible grafts or hybrids across genera are rare enough, and between Orders are extremely rare. Simlarly compatible grafting.

 

I suspect a simpler explanation. The photo at the top of page 2 that suggests a twin stemmed tree forking at ground level has diffrerent bark on the two stems. It maybe that there are two separate trees growing so closely together that they appear to be the one tree but they are neverrthless two trees. The remaining pictures show what looks indeed like torminalis leaves growing from Sorbus barked stems and Cornus leaves growing from Cornus barked stems.

 

Two trees, I'd say. If not, this is the scientific discovery of the decade and would send international geneticists back to primary school in search of their sanity. AS if say a bat had been successfully cross-bred with a snake.

The last option which has not been explored yet is that he is pulling everyone's plonkers

From the photos it looks like 2 different trees, different bark on each stem. Looks like separate leaf growth on each stem too.

I know the bark looks different on both stems, however there are dogwood leaves growing everywhere off of both stems, the only part where the mystery leaf is, is a few branches about chest height on the stem nearest in the picture.

 

Thanks for the help,

Hi Harry. When you have time look up inosculation in trees. This may be the answer to your question. Maybe.

This is a possibility but for inosculation doesn't the cambium from both trees have to touch??

Hi Harry, I haven't long got home and was hoping to find some detailed info on inosculation in one of my books. But no luck. Apparently it can happen at root level. The stems do look very close together, is it possible that they have fused below the pebbles in the pics? I'm not entirely sure that inosculation would allow the trees to share each others genetics and there fore produce leaves of each other.

Yeah i guess the roots could have fused together.

 

This is all very interesting[emoji3]
