Wild Navew.
Bunias
The plant which produces what we call rape seed, and in some places cole-seed. Though wild on our ditch banks; it is sown in some places for the sake of its seed, from which an oil is made for mechanical purposes. The plant is two or three feet high; the stalk is round, upright, smooth, thick, firm, and of a pale green, the lower leaves are long and narrow, very deeply divided at the edges, and of a pale or bluish green colour. Those on the stalk are of the same colour, but small, narrow, and a little divided: the flowers are small, and of a bright yellow. The pods are long, and the seeds are round, large, and black; they are of a somewhat hot and sharp taste. The seeds are used for the same purposes as the other, and are supposed to have more virtue, but probably neither have much.
