Etymology: The plant genus "Najas" shares its spelling with the plural of "naja", the name of the cobra genus, but the two names have separate origins. The plant name comes from the Greek "Naias", a naiad, one of the nymphs of fresh water in Greek myth. Pond and river plants were given a name that recalls these water spirits. The snake name has a different history. "Naja" comes from Sanskrit "nāga", meaning "serpent," which is probably connected to the Proto-Indo-European root *nogʷós, "naked." The shared spelling of the plural form is a coincidence, and the two words have nothing to do with each other beyond that.

Synonyms: water nymph, aquatic plant
