Many plants, again, have been called in memory of leading characters in days gone by, and after those who discovered their whereabouts and introduced them into European countries. Thus the fuchsia, a native of Chili, was named after Leonard Fuchs, a well-known German botanist, and the magnolia was so called in honour of Pierre Magnol, an eminent writer on botanical subjects. The stately dahlia after Andrew Dahl, the Swedish botanist. But, without enumerating further instances, for they are familiar to most readers, it may be noticed that plants which embody the names of animals are very numerous indeed. In many cases this has resulted from some fancied resemblance to some part of the animal named; thus from their long tongued-like leaves, the hart's-tongue, lamb's-tongue, and ox-tongue were so called, while some plants have derived their names from the snouts of certain animals, such as the swine's-snout (_Lentodon taraxacum_), and calf's-snout, or, as it is more commonly termed, snapdragon (_Antirrhinum majus_). The gaping corollas of various blossoms have suggested such names as dog's-mouth, rabbit's-mouth, and lion's-snap, and plants with peculiarly-shaped leaves have given rise to names like these--mouse-ear (_Stachys Zanaia_), cat's-ears, and bear's-ears. Numerous names have been suggested by their fancied resemblance to the feet, hoofs, and tails of animals and birds; as, for instance, colt's-foot, crow-foot, bird's-foot trefoil, horse-shoe vetch, bull-foot, and the vervain, nicknamed frog's-foot. Then there is the larkspur, also termed lark's-claw, and lark's-heel, the lamb's-toe being so called from its downy heads of flowers, and the horse-hoof from the shape of the leaf. Among various similar names may be noticed the crane's-bill and stork's-bill, from their long beak-like seed-vessels, and the valerian, popularly designated capon's-tail, from its spreading flowers.
Many plant names have animal prefixes, these indeed forming a very extensive list. But in some instances, "the name of an animal prefixed has a totally different signification, denoting size, coarseness, and frequently worthlessness or spuriousness." Thus the horse-parsley was so called from its coarseness as compared with smallage or celery, and the horse-mushroom from its size in distinction to a species more commonly eaten. The particular uses to which certain plants have been applied have originated their names: the horse-bean, from being grown as a food for horses; and the horse-chestnut, because used in Turkey for horses that are broken or touched in the wind. Parkinson, too, adds how, "horse-chestnuts are given in the East, and so through all Turkey, unto horses to cure them of the cough, shortness of wind, and such other diseases." The germander is known as horse-chere, from its growing after horse-droppings; and the horse-bane, because supposed in Sweden to cause a kind of palsy in horses--an effect which has been ascribed by Linnaeus not so much to the noxious qualities of the plant itself, as to an insect (_Curculio paraplecticus_) that breeds in its stem.
