Hackberry

Or Sugarberry, or Sugar Hackberry.
This one has given me so much trouble, so much! The problem being is that sometimes the leaves are smooth and sometimes they're serrated. Or that sometimes they're mostly smooth with a few serrations. There are multiple varieties, and the leaves seem to be one of the biggest variable. There's also the problem that there are two different trees that are called the Hackberry, and the more commonly represented one online is the other one. Actually there's another tree called a sugarberry that isn't in the elm family, but that one only grows in very Southern Texas and Mexico - so if you're in Cross Timbers it's not your tree. This tree is in the elm family and is generally considered a good shade tree.
The leaves have three main ribs coming from the stem and protruding veins on the underside of the leaf. The tops of the leaves are rough, even when wet, the tips curve slightly, and the sides curl slightly when the everything is drier (at least that's what it has appeared like over the last couple months). They have short stems, uneven bottom, and droop on the branches. The leaves are simple, alternate, and usually shaped like a spear-head. They are thinner than they are long and grow up to 7 inches long.The bark is pretty uniform between subspecies so that's a worthwhile thing to check out. The bark is a light grey and starts out smooth but gets warty or ridged. This one is so ridged and lumpy at first I thought there was something growing on it. As you can see they can sometimes be multi-trunked.
The berries are drupes (a cherry is a type of drupe, stemmed with one pit) and begin to ripen in September as reddish-yellow and end up to be dark red-brown - almost purplish looking, in fact. The flowers come in the Spring, but as they are light green they're not very visible.
It's either a Sugarberry (Palo Blanco) or a Lindheimer Hackberry. But that's what common names are good for, one name can cover a good amount of things without being wrong. I do don't like being wrong, especially when it means I've spent a good amount of time researching and still get it wrong.
