Of the one hundred and twenty-five species of Mullen that are native to the old world, five have become naturalized in the United States. The Great Mullen (Verbascum thapsus), so familiar in dry, open fields, was originally christened by Pliny and has since received over forty English names of a less classical origin and significance. The name Verbascum is supposed to be derived from Berbascum, meaning a beard. Pliny doubtless selected this name, either because of the hairs on the stems of the plants or on account of the silky character of the leaves. The specific name, thapsus, is said to have been added, as the plants grew in considerable numbers in the vicinity of Thapsus. One of the significant but impracticable common names of the Great Mullen is Hag-taper. The plant gained this unpleasant appellation by reason of the fact that if any one steps on a young Mullen plant after sundown, the witches will ride him as a horse until morning, lighting the way with Mullen stalks used for torches. These torches were also employed at the meetings of the hags and witches, when the leaves of the plant were an important element in the concoctions prepared in their cauldrons. Another name is Hare’s Beard, illustrating a class of plants that have weird names because of some fancied likeness to animals. The name Cow’s Lungwort, arose from the resemblance between the leaf and the dewlap of a cow, from which it was argued that the plant must be a specific for lung diseases. In England, where the Mullen is known as Blanket Leaf, the dried leaf is tied around the throat in cases of colds. It is believed that the leaf sets up a mild irritation which will be beneficial. The dried stalks of the plants were often used for torches at funerals which gave rise to the names High or Hedge Torch. The Great Mullen varies in height from two to seven feet. The stem is stout, very woolly, with branching hairs. The oblong, pale green, velvety leaves form a rosette on the ground or alternately clasp the stem. The flowers, which are about an inch in diameter, are clustered around a thick, dense spike, and have two long and three short stamens, so arranged as to materially assist the process of cross fertilization which is largely carried on by bees. It is interesting to note in connection with the thick woolly covering of the plant that many vegetable forms are so protected when exposed to intense heat or cold. This is true of most alpine and desert forms and the value of such a protection to the Mullen will be seen when it is remembered that the plants are always found in open, dry, stony fields exposed to the fierce heat of the sun, and afforded no protection for the rosettes of year-old plants which must survive the winter in order to send up the flower stalk the second spring.
