(nŏt'grās), n. (Bot.) (a.) A weed-like plant of several species, of the genus Polygonum; — so called from the joints of its stem; knot-weed. (b.) A plant of the genus Triticum (T. repens). See DOG-GRASS.

An infusion of it was once supposed to have the effect of stopping the growth of an animal, and hence it was called, as by Shakespeare, “hindering knotgrass.”
