A friend has a few years old Petite Nigri. It grows different types of leaves on different branches. It has been producing very early as well. Plants propagated from any of these branches have produced both types of leaves on separate branches as well.
 Anyone else have noticed the same with this variety? 

Oh, you could say people have noticed that.

I will say, though, that this effect does make for a subtle landscape accent, because you're looking at all the different leaf shapes over the tree.  Theraputic clover counting, I say...

I don't know how to attach threads Bass, but there is a thread with quite a discussion about the leaves. It's titled something like Is this Petite Negra or Doesn't look like Petite Negra but is it? In that thread I discovered that my plant is actually Aubiqua petite, not Petite Negra. 

Hi Bass.  Here's a link to the thread that Barry referenced:

I was about to post pictures of the two leaf patterns on my Petit Aubique there, as well.  (I have Petit Aubique and Petit Negri... have promised cuttings to a few folks once the trees are dormant).  It's such a wild characteristic, this business of the different leaves, eh?  I know that lots of different cultivars have unstable leaf morphology, and leaves of different shapes on the same tree.  But with this one, it seems so interesting that an entire branch will be consistently one-lobed, yet another branch will be consistently 5-lobed, or 3-lobed, etc.  Maybe there are other cultivars that do that too (Raspberry Latte maybe? I'm not so sure actually)... seems there are a few that are genetically close, so I guess it's possible.  But it is a very striking characteristic that this variety is so consistent on a given branch, and yet different branches almost look like they belong on different trees... how cool!

OK, in the interest of linking to the other thread rather than splitting the discussion further, I'll end with that link:
