Mustard

"A plant of the genus sinapis, a pod-bearing, shrub-like plant," "growing wild, and also cultivated in gardens. The little round" seeds were an emblem of any small insignificant object. It is not mentioned in the Old Testament; and in each of the three "instances of its occurrence in the New Testament (Matt. 13:31," "32; Mark 4:31, 32; Luke 13:18, 19) it is spoken of only with" reference to the smallness of its seed. The common mustard of Palestine is the Sinapis nigra. This garden herb sometimes grows "to a considerable height, so as to be spoken of as "a tree" as" compared with garden herbs.
