Treacle Mustard

Descript : It rises up with a hard round stalk, about a foot high, parted into some branches, having divers soft green leaves long and narrow, set thereon, waved, but not cut into the edges, broadest towards the ends, somewhat round pointed; the flowers are white that grow at the tops of the branches, spike- fashion, one above another; after which come round pouches, parted in the middle with a furrow, having one blackish brown seed on either side, somewhat sharp in taste, and smelling of garlick, especially in the fields where it is natural, but not so much in gardens. The roots are small and thready, perishing every year.

Give me leave here to add Mithridate Mustard, although it may seem more properly by the name to belong to M, in the alphabet.
