A plant kept in some gardens, and not unlike the common turnip in its aspect and appearance. It grows a yard high. The stalk is round, smooth, and of a pale green. The leaves stand irregularly on it, and they are oblong, broad at the base, where they surround the stalk, and narrower all the way to the point. The leaves, which grow from the root, are much larger and deeply cut in at the sides; and they are all of a pale or bluish green colour. The flowers are small and yellow, and the pods are long. The seed is round and black. The root is white and large, and has the taste, but not the round shape of the turnip, for it is rather like a parsnip.
The seeds are used, but not much. A decoction of them is said to promote sweat, and to drive any thing out to the skin; but it does not seem to deserve any great regard.
