Hi, there are 2 trees in my neighborhood. I identified them both as elm according to a Tree ID site. However they are both very different. One has leaves that are varied in size, some about 4 in x 2.25 in or 3 in x 1.75 in. The other tree has small leaves, about 1.5 in x 1 in (I didn't measure). The one with small leaves, the leaves are very symmetrical on either side of the branch. The other larger one, the leaves are not that symmetrical, and there are offshoot branches with leaves. Here are 2 photos and 2 movies. Could they both be varieties of an American Elm?

Maybe an Elm and an Alder (based on leaves alone). Please go back and take photos of the trees in question: the entire tree plus branches, leaves, bark, any seed pods, etc.

Watching home movies dozens of times trying to see what I want to see is too difficult.

Thanks Daisy L. I will take more pics. Thanks.

Actually I found some more photos I took that might help.

Here is the tree with the small leaves.
















Here is the tree with the medium sized leaves.

You are right - both are elms.

Thank you for posting more photos. They were very helpful.

Do you know if they are both American Elms?

The one with little leaves might be cedar elm, if it grows there.

Both elms but not the same kind.

The tree with large leaves tree is probably American Elm (Ulmus americana) . The tree with small leaves is probably Siberian Elm (Ulmus pumila) . However, neither the leaves nor the bark can give a definitive ID. Really need a picture of the samaras (winged seed pods) to know for certain which species of elm they might be.

I was also thinking the smaller leaves could be Siberian Elm.

Thanks so much.

The elm with the small leaves on the left is Siberian Elm, a poor quality tree, and the one on the right is either Slippery Elm or American Elm. The American Elm forms a good vase shape and its leaves are not as rough as the Slippery Elm.

Thanks Rick Webb
