Texas Ash is a small tree, 30-45 ft. tall, of limestone hills and canyons with an attractive, densely branched canopy. Pinnate leaves have brilliant fall color. Leaflets usually 5, rounded, not as elongate as in Red Ash (Fraxinus pennsylvanica). Wings usually not extending beyond the middle of the seed. (See Red Ash for comparison.)Confined to Texas, except for a northern extension into the Arbuckle Mountains of Oklahoma. This southwestern relative of White Ash (Fraxinus americana) has fewer and smaller leaflets and smaller fruit and is adapted to a warmer, less humid climate; some consider it a variety of that species. Name changed from Fraxinus texensis to correct an issue of nomenclatural priority. Male and female flowers are borne on separate trees.
