Its flow- ers are in lateral clusters ; the samara is larger and with a broader border. The inner bark contains a great quantity of mucilage, of much value in medicine. Michaux considers its wood as superior to that of the white elm. The tree can be readily grafted upon the white American Elm (Ulmus Americana). elm, and if only for ornament it is well worthy of cultivation. The corky white elm ( U. race- mosa, Thomas) has its branches often beset with corky ridges ; its leaves are similar to those of the white elm; its flowers are in racemes ; its wood is tougher and finer grained.
