OK now, On the first pics ( 3 ) here is the tree that this bud came from. Maybe it will help. Looks almost like a Smoke tree but it is something else and they are everywhere in my area...not planted just random in the woods and in people's yards.
One the second set, it is starting to look more Elmy or more Elm-like. Here is a picture of the leaves at about 12' on a slender trunk. No branches and just the leaves at the tips. Just long straight trees. The lighter colored leaves in the middle of the pic. nThe leaves are alternate.
