Polygonum
See also: polygonum
Translingual
Polygonum aviculare (common knotgrass)
Etymology
From Ancient Greek πολύγονον (polúgonon, “knotweed”) from πολύς (polús, “many”) + γόνυ (gónu, “knee”) (though γόνος (gónos, “offspring”) has been suggested- the "knots" in "knotweed" are enlarged joints like knees, and it's certainly a prolific weed, so either derivation is plausible).
Proper noun
Polygonum n
- A taxonomic genus within the family Polygonaceae – including the various knotweeds, smartweeds, and bistort.
Usage notes
Sensu lato has frequently included the genera now in the tribe Persicarieae as sections, that is Persicaria, Bistorta, Cephalophilon and Koenigia (which last has also been delimited as Rubrivena and Aconogonon).
