軟花屬植物
Knot·grass n. Bot. (a) a common weed with jointed stems (Polygonum aviculare); knotweed. (b) The dog grass. See under Dog.
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.”
We want a boy extremely for this function,
Kept under for a year with milk and knotgrass. --Beau. & Fl.
