Knotgrass
Knotgrass Knot"grass`, n. (Bot.) (a) a common weed with jointed stems {(Polygonum aviculare)}; knotweed. (b) The dog grass. See under {Dog}. [1913 Webster]

Note: An infusion of {Polygonum aviculare} was once supposed to have the effect of stopping the growth of an animal, and hence it was called, as by Shakespeare, ``hindering knotgrass.'' [1913 Webster]
