Leaves are deciduous, alternate, simple, 2-4" long, about half as wide, elliptical - ovate shaped, double serrated margins, upper surface quite scruffy (stiff hairs, scabrous) with the lower being slightly so as well as having lots of pubescences in the axils of the veins. Marginal yellow fall color.
Stems generally slender, zigzagging, light brown or slightly reddish. May have lots of irregular corky growth. Not symmetrical like others like the U. alata which had 2 distinct rows of cork.
Flowers before leafing out in early spring, flowers reddish color.
Fruit is a rounded samara, about 1/2" diameter, papery when dry, seed in the middle of the fruit, tip of the samara lightly notched.
Bark is deeply ridged.
Look for the seriously scabrous upper leaf surface, as well as the pubescent lower and the leaf size. Fruit is always helpful identifying elms.
