释义

pondweedn.

Brit. /ˈpɒndwiːd/, U.S. /ˈpɑn(d)ˌwid/
Forms: see pond n. and weed n.1 Also with capital initial.
Origin: Formed within English, by compounding; modelled on a Dutch lexical item. Etymons: pond n., weed n.1
Etymology: < pond n. + weed n.1, originally after Dutch †fonteyn cruyt (1554 in the passage translated in quot. 1578 at sense 1; now fonteinkruid).
1. Originally: either of two aquatic plants formerly considered to belong to the same genus, (more fully broad-leaved pondweed) Potamogeton natans (see below) and † (more fully narrow-leaved pondweed) the floating form of amphibious bistort, Persicaria amphibia (obsolete). In later use: any of the numerous aquatic plants constituting the cosmopolitan genus Potamogeton (family Potamogetonaceae), which typically have submerged leaves and inconspicuous flowers. Also (more generally): any plant of pond or stagnant water, particularly one with inconspicuous flowers; esp. duckweed (genus Lemna).
