Hi all,

I am not familiar with this tree, but we've heard that there are possibly two different trees being represented in this same PlantFile entry. Here's a link: http://davesgarden.com/guides/pf/showimage/250973/

Since I don't know, I'm asking if anyone can help?

Thanks!

Joan

I just get this:

Quoting:

I just released one additional photo to that entry that may belong to one of the trees, if there are in fact two different ones in the entry.

Looks OK to me, all the pics are correctly identified. It is one of those plants where there is a huge difference in leaf shape between young (deeply lobed leaves) and adult (unlobed leaves) trees. Perhaps the person making the query wasn't familiar with that?

Thanks Resin! Perhaps, like me, they aren't familiar with the tree. I wondered it was a difference between young and mature leaves, but I couldn't verify that.

Your help is much appreciated. Thanks!

I agree with what Resin stated, except that I don't necessarily believe that it has to do with the age of the tree.

Many people don't realize the incredible difference between leaves emerging from dormant buds, and leaves produced on new growth of the season. Broussonetia and Morus are famous for this. Sassafras has its own varied leaf morphologies related to socks, gloves, and mittens, etc.

I've posted this kind of comparison of images in the entry for Morus rubra; see here:

The images were taken of the same tree on the same day.

So you're saying that the difference in leaf form on the same tree depends on whether the leaf grew from leafbuds formed on last years growth vs. leafbuds formed on this years growth?

This is very interesting.

Yep, agree with V V - the reason being that sprout shoots from long-dormant buds show reversal to juvenile growth.
