Bifurcated Leaf Mutation on Elm

[DeepSouth]

Today I noticed that two of the leaves (same branch) on my winged elm (Ulmus alata) that I collected this year have developed with some kind of mutation (I assume somatic) that caused the leaves to become bifurcated.

Very unusual, I am curious if anyone else has seen this on their bonsai??

I haven't seen it on my bonsai, but I have seen it a lot in other plants. It's usually a couple leaves and no more, and most of the times it happens just once per plant.

Yeah, see it from time to time, particularly on elms, maples to. Can be do to damage to the leaf bud. I've seen in wild trees as well.

It’s funny I just had this happen too!

It was on new growth that grew on a Siberian elm that I cut down to just a few inches.
My thought is that I was just trying to push through and didn’t care how it came out.
It was on about a fifth of the total leves
