The American lime, or basswood (Tilia Americana), is the most robust tree of the genus, and produces much more vigorous shoots than the European species. It prefers a deep and fertile soil, where the trunk grows remarkably straight, and the branches form a handsome, well-rounded summit. The flowers are borne on long stalks, and are pendulous from the branches. The leaves are large, heart-shaped, finely cut on the margin, and terminated by a point at the extremity. The seeds, which ripen in autumn, are like small peas, round and greyish.
