Try the Tree form or Name That Plant forum.

Probably an elm (its leaves are not compound). And with rough bark and suckers probably English elm.

For best results with plant identification questions show entire plant habit in addition to close views of all significant parts present. With elms in particular, which often ripen their wafer-like fruits in spring good close views of these can be important.

Thank you for your help lacey. If I can find some more pictures, I will repost on the Name That Plant forum. Looks like Houzz has locked the original post. Worst case, I will be back out within a week and will take more.

Embothrium, I apologize for the lack of pictures. I was taking some when my neighbor struck up a 45 minute conversation- great to speak but I lost my train of thought afterwards.

-Did my Imgur picture link work? The pictures there are much higher resolution.

-Unfortunately I am not sure tree #1 is an elm (unless you know of an elm with nonserrated leaves). I also did not see any samaras this spring on these trees. I have some American Elms a few miles away and was watching when they put on their spring show. If it helps at all, the mystery tree appears to have been planted fairly frequently in some parts of town about 100 years ago. While they aren't present in the newer neighborhoods, they still line a few of the streets paved back in ~1900. Apparently a fairly hardy tree!

The bark looks very similar to Sugarberry bark, however the leaves are not serrated. Odd!

Sugarberry seems to not always have serrated leaves. Do a google search and you will see.

Thanks a bunch, it looks like these are possibly Texas Sugarberries. https://courses.missouristate.edu/pbtrewatha/texas_sugarberry.htm

Sugarberry for #1 and the leaf descriptions I've seen say that leaf serration is not always present. Bark is unmistakingly Celtis. Virginia Tech Dendrology

Actually the twigs are wrong for English elm too, which usually produces winged or ridged ones.

Embothrium, I guess you learn something new each day! I just read that Sugarberries are in the same family as cannabis... O.o I guess I have something to brag about to my friends in Colorado now! lol

The cannabis connection is actually pretty recently discovered, before that sugarberry and other celtis was believed to be related to the elms. But I guess the hops used in beer are closer related to cannabis than hackberry/sugarberry are.

#1 = Sugarberry (Celtis laevigata?)

And as mentioned, it was previously thought to be in the Elm (Ulmaceae) family...but after recent DNA testing, may actually be in Cannabaceae (Cannabis).

#2 = American Elm (Ulmus americana)

blakrab, interesting! I did not think #2 was another American Elm. Apparently I have a few (and none that I can see are showing signs of DED). In fact, American Elms seems to grow prolifically here.

^ There are many American Elms in Texas. DED doesn't seem to have struck here much (yet?)...

Come of think of it blak, I recently cut down a couple very dead trees (please see pictures at the following Imgur link). Looking at my pictures of the bark and their form again, I wonder if these were elms? If so, do you think these succumbed to DED?

I'm also including a picture of one of my other properties. You can see the ~40' American Elm at the edge of the forest. Very graceful trees.

^ Dunno, I have no personal experience with DED? As I think it hasn't become "epidemic" in TX yet:

"Very little research has been conducted regarding Dutch elm disease in Texas and little is known about how the disease will progress through the state. Early observations indicate that the disease is not slowing down, and is causing damage on both public and private land."

"Dutch elm disease, a fungus related to oak wilt, which destroyed as many as 40 million elms. The fungus, which came to the United States from Europe arrived here in 1930 and was confirmed in Texas in 1970."

BTW, I wonder if #2 could also possibly be a Slippery Elm (Ulmus rubra)? The 2 are very similar, except the Slipper Elm's leaves are almost the same as American Elm, but are much scratchier due to high silica content in the leaf.

^ Isn't it odd that DED seems to have slowed down/stopped when it hit Texas? If the disease hasn't slowed, why aren't all my elms dead? Some of them are easily 40 years old (visible on aerial photos). I read that the disease ravaged the rest of the country within ~50 years of introduction. Yet, it has taken almost 50 years to see any significant outbreaks past the state line? Perhaps there is a naturally resistant local variant of the elm here? Maybe the hot summers are an unfavorable environment for the beetles?

The next time I am out at the property, I will examine the leaves of that tree more closely to see if they are scratchier.

Thanks again!

^ Yea, I wonder if DED may not be as much of a threat here due to the hotter climate, or something?

For example, I just took this picture today of an American Elm (leaves weren't scratchy). Of which, I'm guessing yours is likely also an American Elm then, too...
