The seeds of these plants only are used in medicine. The common sort is a native in the southern parts of Europe; and the seeds of this species are larger,.paler, and very different in flavour, as well as in medical power, from the true, which is a native of Egypt; and the seeds are of a reddish brown colour, small, and flat on one side, convex and furrowed on the other.
