The Ivy is found throughout most of the countries of Europe, and also in parts of Asia and Africa. It was one of the sacred plants of the old Egyptians, and held the same character among the Greeks also. In our own western hemisphere the Ivy was unknown until introduced by the colonists from Europe; nor does it seem likely ever to become, like so many other contributions of the old countries, naturalized here; our dryer summers or colder winters, do not apparently agree with it. Possessing one qualification rare among climbing plants, that of being an evergreen, it may, on this account, be considered as the finest of the purely ornamental vines of temperate regions. It is believed to live to a very great age, as the parent stems of vines still attached to buildings some centuries old, are found nearly as large as the trunks of good-sized forest trees. NOTE I. THE SNOWDROP, page 70. Mr. Knapp tells us in the text, that in England the Snowdrop will linger longer than any other plant on the site of a deserted garden, outlasting, in this way, as a memorial of human tillage even the rose- bush, the plumb-tree, or the daffodil. With us the pansy, heart’s-ease, or garden-violet appears to have something of the same character; we have found it opening its pretty, lowly blossoms among the grass, the only vestige of a flower-garden, ploughed up more than thirty years earlier. NOTE J. THE VERVAIN, page 71. We have in the United States several native Vervains, and one species of European origin; the nettle-leaved Vervain, _Verbena urticifolia_, has become one of our road-side weeds. We are told that verbena was a Latin name given to any sacred herb, and by no means confined to the single family of plants to which the term Vervain is now applied. NOTE K. THE MISTLETOE, page 71. The Mistletoe has been sometimes asserted to be unknown in America; but this is an error. The yellow Mistletoe, _Viscum flaviscens_, is found on the trunks of old forest trees, the elm, the oak, and the hickory, in the middle, western, and southern states of the union. This singular parasitic plant has yellowish leaves, with white berries tinged with the same color. _See Gray’s Botany._ NOTE L. DYER’S WEED, WOLD, (_Luteola reseda_,) p. 72. Dyer’s Weed, Weld, Wold, _Luteola reseda_, has become partially naturalized, here and there, in western New York. It is a plant about three feet high, from whose leaf and stem a yellow coloring matter is obtained, which is preferred to all other substances for giving a brilliant greenish-lemon tint. It is also much used for dyeing silk a golden yellow.
