Najas is a genus of about 50 species of aquatic plants, with a cosmopolitan in distribution. It usually is taken to be a single representative of the family Najadaceae, but APG II places it in the Hydrocharitaceae. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...
