Mithridate Mustard.
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.
