What kind of persimmon is this?

This is a persimmon tree in my yard.  It is one of a bundle of 10 or 12 that I bought from penn state extension about 10 years ago.  I had initially assumed they were all seedlings.  Now I'm pretty sure they might all be clones of certain american persimmon varieties.   I think there were at least three types in that bundle.  One male, one traditional looking wild persimmon, and this one.  

Fruits are very small, like a smallish grape.  I pick them now, after they turn dark and dry a bit, making them less likely to be astringent.  No seeds to be seen.  It has a different branching structure than what I think of as the typical american persimmon.  There is at least one other tree i have from that bundle that I believe is likely the same variety based on the structure but no fruit yet to compare.

There's a small chance I started this from seed.  I started some princess persimmon seeds, but lost track over whether any of them made it and got transplanted into the yard.  

It also happens to look similar to a princess persimmon but not as big or fancy/glossy looking.  

Of all the pictures I see of persimmon fruit on the internet, no fruit is this small.  It's really more of a berry in size.  Is anyone familiar with this?  I am curious.  

If these pictures upload, the taller tree with the larger fruit is the more traditional american persimmon tree and fruit.  Thanks.

they are tiny, aren’t they? small with no seeds generally means incomplete pollination, which might suggest it’s genetically more different from the others. there are two main genetic groups of american persimmon, the tetraploid  60-chromosome ones are from the southern appalachians, and the hexaploid 90-chromosome ones farther north. many individuals in both groups are parthenocarpic - they make seedless fruit if not pollinated.

i’ve seen both american and asian individuals with the long thin ‘acorn’-looking fruit. the asian ones are usually so much larger that i doubt those little guys have much if any asian ancestry.

They are just a really small American persimmon. Kinda cute. Do they have seeds? Pollination indeed can improve the size. I’ve encountered wild persimmons with very small fruit, but never quite that small

They have no seeds.  On the one end in the pulp they seems to have a circle of black dots where the seeds would be.  So you can eat it like a seedless grape or a raisin.

Your tree looks lovely!  My guess is that you have a date plum, i.e. Diospyros lotus.  I found this youtube video where they mention that lotus persimmons are used as rootstocks.  He lost the graft and ended up with the rootstock growing into a lovely plant.  Maybe you got yours the same way?  

Thanks Greg,

I think you figured it out.  Date plum (diospyros lotus).  I looked up a couple other videos on youtube and found some that had a look more similar to mine as far as the skinny acorn like shape.

What he says is true about the astringency.  They should be dark and a little shriveled to eat.  

Im still curious if any on my other trees will turn out this way and if I got this from the bundle of persimmon trees or from seed or was just a rootstock.  I think at at some point I also had a packet of date plum seeds from tradewinds fruit.

It's nice knowing the variety if I have to look something up or someone else wants to know the type.

being a different species makes the no-pollination thing make more sense, too. i wonder if you’ll start getting seeds when the others like this start flowering.
