They are not likely to appear on any lists, as they are not considered a marketable wood, and seldom are harvested for lumber.
I imagine that they would be pretty close to other elm wood. In my experience, they are pretty similar in weight & strength to American elm & slippery elm, although not quite as fibrous and strong.
Elm is one of the preferred woods for flooring on semi-trucks. The wood is so fibrous, it tolerates many years of getting nails pounded in to hold freight, with subsequent removal. The fibers of the wood just seem to close back up around the nail holes.
If you ever tried to split much elm for firewood, you know how the fibers hold together.
