Mithridate Mustard.

Botanical name: 

Thlaspi incano folio.

A little wild plant, common in corn-fields. It is of a foot high; the stalks are round, firm, upright, and not much branched; the leaves are long, narrow, a little hairy, and of a dusky green. The flowers are small and white, and the pods which follow them are roundish and little, not flatted as in the former kind, nor surrounded with a foliaceous edge. The leaves grow very thick upon the stalk, and each has as it were a couple of little ones at the base.

The seed of this is used also, at least in name, for the cress seed serves for both: the matter is not great, for they seem to have the same virtues, and neither is minded, except as ingredients in compositions.

The Family Herbal, 1812, was written by John Hill.
