"We will take the linden, lime, or basswood, tree--for it has all three of these names--this evening," she continued, "and there are nine or ten species of the tree, which are found in America, Europe and Western Asia. It is a very handsome, regular-looking tree with rich, thick masses of foliage that make a deep shade. The leaves are heart-shaped and very finely veined, have sharply-serrated edges and are four or five inches long. The leaf-stalk is half the length of the leaf. It blooms in July and August, and the flowers are yellowish white and very fragrant; when an avenue of limes is in blossom, the whole atmosphere is filled with a delightful perfume which can hardly be described."
