Lacebark Elm (Ulmus parvifolia
) should certainly be among the common elm species planted in the DFW area of Texas, but I imagine that there are others.
The bark character illustrated doesn't match any Lacebark Elm that I'm familiar with - which are mostly clonal selections with patchy colorful exfoliating bark that are planted in the Ohio River valley region. These could be examples of seedling Lacebark Elm trees, or some other small-leaved species entirely, that has this ridge/furrow bark character.
The color of the buds does not match another small-leaved species, Ulmus pumila
, which typically has fat rounded blackish buds.
This could be one of many hybrid elm selections (NOT American Elm clones, which would have larger foliage) produced for tolerance of stressful urban conditions, which include such stellar performers as 'Triumph', 'Regal', 'Patriot', 'Prospector', 'Homestead', and 'Accolade'.
Here is a link to some interesting work on trialing these selections, and good descriptive information on several of these trees:
