Funny fan leaves: mutation?

[NorthernCosmos]

My White Widow auto leaves has a funny thing going on. On some leaves the end of the petiole has grown into a two or three way split with the individual leaves sitting on those in groups of up to 4. There are cases of 8 and 9 "sub leaves" (what do you call them...? [1]). Perhaps 25% of the leaves has this split petiole going to some degree.

I've not seen that on other plants, including browsing lots of leaf pics. They seem to consistently have the petioles ending in a singe "button" where the individual leaves are attached. Is this a mutation then? Is i common? Only White Widows? Autos?

It doesn't bother me since the plant has lots of nice colas, but I though I might run it past the veteran growers just out of interest.

Here's one such leaf, having a 3 way split with groups of 4, 1 and 4 individual leaves (it's soon chopping time, and I have probably pinched that leaf during handling, so don't worry about the scruffy appearance):

[1] Edit: OK, so the whole thing is a compound leaf and each leaf is a leaflet. The arrangement where all the leaflets grow directly on the end of the petiole, as for cannabis, is called is palmately.

Should have read up on that before posting... sorry - if nothing else I can now share one of my newfound references:

No takers?

I now wonder if this mutation from the usual palmately compund leaf to something between palmately and pinnately is so common that there is no interest, or so rare that nobody knows what to say

It’s not common, but I have seen similar oddities on the forum. Such as this one. I forget who posted it.

Looked better when it was wet had 2 tips on it

I had a leaf off of a lsd 25 that was twisted like you was on LSD but think it fell outa my book and the dog or cat ate it

Hey, other mutations - that's cool folks! Feel free to post more mutation pictures

The ones in Weaselcracker's image are truly strange

You jinxed me found a baby leaf this morning the one I can't find had all 5 fingers doing this

 

[NorthernCosmos]

Whoops... sorry Jake... Then again, perhaps the odd mutations is a good sign? Yeah, let's go for the latter: "a special unique trait reveals itself, just for you"

It looks like there are two petioles. Was that one leaf a merger of two?

 

[Bigjake8]

I think one leaf

Not saying it is caused by this, but plants can get a virus like humans. Recently saw a mr-canucks video of one of his plants affected by tobacco mosaic virus, Twisted leaves etc. You can find the video at weed tube.
